PSS is proud to share our projects


PSS Distributors are proud to support Victoria Health in providing UPS systems for the current COVID – 19 rollouts.

Vic Health have selected our Medi – X 5 to provide medical refrigeration across sites organised by the State Government.

Our Medi – X 5 is an easy plug and play design, which assists the sites in a quick rollout. This unit comprises of a 2kva UPS, along with battery bank for extended run time.


New South Wales

We have just supplied units to the NRL,  they were requiring back up and the units supplied were the PMU-10, PMU-20X and an EN3000.  These units are perfect for camera surveillance, gates, telephone systems and more heavy duty for those larger applications.


Western Australia

We have supplied and commissioned units for Rockingham Hospital, they were after reliable and efficient units that could support their large requirements and we were able to offer the E-Power range.

The EP series offer varying run times and is perfect for any application that required a high level of reliability including remote industrial sites.



PSS Distributors has been selected for various NDIS locations to provide battery back up to critical equipment with their UPS systems, proudly supporting the National Disability Insurance Scheme.

PSS has used their GP range across all sites, best known for its reliability, it is specifically designed with a Galvanic Isolation Transformer for the medical industry. The specification has been checked before installation by engineers and the NDIS, passing every time.


For more information on projects we cover, please contact us.

What is an Anderson plug connection?

An Anderson plug connection is used to provide a safe and efficient power source for DC (direct current) circuits, it is a heavy-duty connector which looks like this:

What is an Anderson plug connection

The Anderson connection is most used in caravans, campers, and tow vehicles. At PSS we use Anderson connections to connect our EBM (external battery modules) to the UPS, this provides power and charge to the EBM.

UPS that are purchased with EBM are supplied with the Anderson connection for the UPS and the EBM’s. The Anderson’s can be connected to the UPS and EBM on site, but this is generally done by a technician at PSS before being shipped out. On site the Anderson plugs will just need to be plugged into the reciprocal Anderson, via plugging negative into negative and vice versa

The Anderson charger on the UPS is customised to the number of EBM attached to the UPS for efficient timely re-charging of batteries.

PSS now stocking 10 year life batteries at all branches!

PSS Distributors is happy to share that we now offer 10-year design life batteries on most UPS.

Our standard batteries are known as 5-year design life UPS batteries, to read more about the expected life span of those please click here. 

With an increased demand for longer design life batteries, we now offer these as an accessory in all UPS (excluding the Eco-Alto range). Stores nationwide now stock these batteries as a standard which makes assembly of these UPS a seamless process.

We are seeing the most demand for these long life batteries in the medical field and remote installations for critical site, this is usually sold in our Medi-X and GP range of UPS.

To read other blogs we have written about other long design life batteries, including lithium, Nickel-Cadmium UPS Batteries, Lithium Iron Phosphate UPS Batteries  click here.

For any further questions on the different type of batteries we offer please contact us.

What is the difference between IEC plugs – C13, C14, C19 & C20

This information will cover the following connections – specific to Australian appliances:

  • IEC C13 at 10amps
  • IEC C14 at 10amps
  • IEC C19 at 16amps
  • IEC C20 at 16amps

Starting with IEC C13 and 14 at 10amps

IEC is a 3-pin power cable (L, N & E) used mainly for computer, communications, and other appliances.

IEC C13 is also commonly called a “kettle cord” and is the male connection that fits in IEC C14 – female. These are rated to a maximum of 10Amps.

IEC 13/14 are commonly used to power appliances; they plug in with a standard 10amp 240v plug.

At PSS Distributors, UPS 600va – 2.2kva use IEC 13 connection, making them an easy plug and play design.



IEC C19 and C20 at 16Amps

IEC 19 and 20 are still 3 pin connections but slightly different to the 13/14 connection, IEC 19 and 20 connectors are designed to carry a higher current of up to 16amps. The different shape of the connectors ensure they cannot be connected together.


Often an appliance that draws over 10Amps and under 15Amps will come with a 15Amp AUS Standard 3 pin plug to a C19 for the input power.

15amp Aus plug

At PSS Distributors all our 3kva UPS use IEC C19 and are plugged into a 15 AMP socket. This is in line with Australian standards.

So, what is the difference between 10 AMP and 15AMP AUS standard plug?

10 and 15amp are both single outlet, single phase circuits. However, 15amp has a heavy duty (thicker) wire to carry a larger current and the socket on a 15amp plug has a larger earth. 15amp plug needs to be plugged into a dedicated 15amp socket due to the larger earth, but a 10amp plug will fit into a 15amp socket, please see example below of the 10 and 15amp sockets.


Any UPS we sell above 4kva would need to be hardwired in by an electrician, this again is in-line with all Australian standards.

If you have any further questions about connection types, please get in touch with one of our technicians.

PSS Provides Backup to NSW Rural Fire Service

PSS Distributors is proud to have a UPS providing backup at NSW Rural Fire Service (NSW RFS).

What can small businesses do to play their part in going greener?


There’s no denying we live in a world with too much waste, and we are all facing the real effects of climate change. At PSS we are playing our part to eliminate waste and become greener overall. These are the things we have made changes to recently:


    1. MSB and SSB packaging – our newest product (outdoor enclosures) uses the least amount of packaging and plastic yet; however, we still ensure safe and secure transportation – just avoiding huge waste of packaging.
    2. All stores have recycling facilities – All stores have an additional bin for recycling purposes to ensure the waste we do have is disposed of correctly. Staff are trained with the appropriate skills of discarding waste.
  1. We recycle all batteries – We recycle all batteries appropriately, recycling is an economical and environmental way to solve the problem of landfill and taking on a responsible stance.


  1. Try our best to minimise all plastic with orders – All storeman use the least amount of packaging when sending goods.


  1. Less paper overall – Moving into the generation of going green and understanding the need to participate in cleaning up the environment, we understand the small gestures that are so important; hence all invoices are sent via email at the close of every workday.


  1. Less local freight – we have increased storage facilities in all states to reduce local freight which reduces petrol and packaging and thus contributing to reducing our carbon footprint, all while helping customers save on freight costs.



Do you have any more tips for us? What are you doing to go greener in your workplace?

How to setup a server rack, successfully!

The steps below will take you through what to keep in mind when purchasing and setting up a server rack. We will go through where to keep it, what size to buy and useful accessories to consider.


Firstly, you need to consider your long-term placing of the server rack. At Redback Racks, all our floor standing racks come standard with castors and stabilising feet, it is always best practice to wheel your rack into a suitable position before setting up your equipment. Other things to keep in mind when deciding where to keep your rack include:

  • Accessibility
  • Heat
  • Noise

If you do not have access to a server room, you may want to consider an acoustic rack for noise reduction.


Now that you have found a place to keep your server rack you need to consider the size of the cabinet.

  • How much space do you have available?
  • How much equipment will you be storing in the rack?

To read more about selecting the correct size rack please click here.



The last thing to consider when purchasing and setting up your server rack is the accessories you need with it.

All Redback racks come standard with cage nuts, shelves and castors/stabilising feet for floor standing racks or wall mounting brackets for the wall mount units. Other accessories you may need to consider are:

  • Ventilation – keeping your equipment at optimum temperature may extend the life and assist it running. Our ventilations options include a range of fans, digital monitoring units and aircons.
  • Cable management – We’ll let these images do the talking of advantages of cable management

Cables messy vs organised with cable management



If you have any other questions in selecting the correct rack, please contact one of our friendly staff.

How to select the correct size server rack

At Redback racks, we liked to keep everything simple! When assisting our customers to select a rack, we ask these 3 questions:

  1. Height in RU
  2. Wall mount or floor standing?
  3. Depth?

These handy mouse pads are part of our promotional gear to assist customers.

Height in RU?

Server rack height is measured in rack units (RU), 1RU = 44.45mm.

Most racking equipment is also measured in RU, for example 1 x patch panel = 1 RU.

Add your equipment together to establish the RU of your rack.

If it is a large rack and a lot of heat generating equipment, you may want to add 1-2RU extra to allow for ventilation throughout the cabinet.


Wall mount or floor standing?

At Redback Racks our wall mount racks come in 6, 9, 12 and 18RU, floor standing come in 18,27 and 42RU.



Depth of most cabinets and equipment is measured in mm, standard depths of our cabinets are 450 and 600mm for the wall mount units and 600, 800mm & 1000mm in the floor standing units.

When selecting depth of your rack, be sure to look at the specs of your equipment to ensure it will fit.


Adding on from the questions above, all server racks are usually 19” internally and most equipment is compatible with this, 19” = 482.6mm

At Redback Racks we have the option of 600mm and 800mm externally and the internal width is standard 19″.

The difference between the 600 and 800mm wide is 100mm either side of the equipment to allow for cable management. These larger 800mm wide server racks are mostly used in larger cabinets, 42RU and above.

We hope this helped in selecting your cabinet size, if you have any other questions in please contact one of our friendly staff.

PSS is selected for multiple NDIS locations


PSS Distributors has been selected for various NDIS locations to provide battery back up to critical equipment with their UPS systems, proudly supporting the national disability Insurance scheme.

The specification of the NDIS asks for backup on 2 circuits for a total of 2 hours. PSS has used their GP range across all sites, the GP range is best known for its reliability, it is specifically designed with a Galvanic Isolation Transformer for the Medical industry. It can handle high and varying loads as well as large inrush current. The specification has been checked before installation by engineers and the NDIS, it has passed every time.

PSS keeps stock of our GP range nationwide to assist in quick roll out times for these projects. If you have any questions, please contact us.

Which UPS would be best for my CCTV system?

If you’d like to read about why we suggest you need a UPS for your CCTV system click here, if you’ve come from that article and you’d like to know which UPS system would be best for your CCTV system, we’ve got you… keep reading!!

We’re going to skip through all the technical lingo and get right down to the run times each UPS will provide your CCTV system.


We’ve made it easy for you by assuming the amount of camera’s, starting with the most common household setup, 4:



4 x camera & NVR (80 watts) 8 x camera & NVR (160 watts) 16 x camera & NVR (200 watts)
Eco-Alto 600va UPS for CCTV Camera Systems 35 28 16
Eco-Alto 800va UPS for CCTV Camera Systems 38 31 19
Eco-Alto 1000va UPS for CCTV Camera Systems 72 56 28
Eco-Alto 1400va UPS for CCTV Camera Systems 85 60 36
Eco-Alto 2200va UPS for CCTV Camera Systems 145 112 70

*All calculations are estimations only

*Calculations are based on standard cameras (10watts each) and NVR with 3T storage and a modem  (40watts).

*PTZ, temperature and Bullet or turret dome cameras have a higher load.


The Eco-range is our entry level product and could provide a long enough run time if a burglar were to turn the power off before attempting a break in.

If you’d like longer run times, we have a range designed for security cameras to achieve run times for up to 36 hours, you can read about our CamSecure range here.

For any other run times please visit or calculator or contact us and we will a happy to help.



What are the benefits of using an external manual Bypass on UPS installations?

Starting with the basics, what is an external manual Bypass?


An interlocking manual bypass is used to retain power to critical equipment during UPS downtime seamlessly.

In layman’s terms “Bypass” is to go around, in the context of a manual bypass used on UPS systems, the bypass allows the power to go around and isolate the UPS, which may be necessary in event of UPS downtime.

Below is a basic image demonstrating the use of an interlocking external manual bypass (if you’re require more technical info, please contact us)

UPS Bypass demonstration

In image 1 we see the UPS operating normally, image 2 demonstrates how the equipment would operate with the UPS in bypass, using an external Bypass.


What about the Bypass that is included with the UPS?


At PSS all of our online UPS come with an internal bypass :

  1. The bypass is internal
  2. The bypass is automatic

Australian standards state, for safety reasons, all manual bypasses need to be external to the UPS to isolate for service purposes.

Below are images showing the internal bypass.

  1. Position of the internal bypass
  2. The mimic clearly indicates if the UPS is Online or in bypass











So, what are the benefit of an external manual bypass over the internal bypass included with the UPS?


In Essence, not having an external manual bypass would be for the critical equipment to be switched of in the event of UPS downtime.

Corporations trust UPS systems on their most critical equipment, this is where the Interlocking external manual bypass allows seamless maintenance and repair on the UPS without any interruption to the critical equipment.

UPS Topology – Line interactive vs Online double conversion

There are two main UPS topologies, line interactive and online double conversion. We are going to explain these and assist you to select which one would be best for your application.

This information is broken down into two parts; the layman definition, written by myself (I have a marketing and sales, non-technical background) and a technical definition, which we will be explained by our technical manager.

Layman definition

Line-interactive, the load is always running off the mains power, when the power is cut there is a short change-over time to the batteries (approx. 6ms) Line-interactive the power always go through and AVR and Surge protection before the load, thus the power is still being “cleaned”.

Online, the load is always running off the batteries, so we always have a controlled frequency (50Hz) and AC output (230V AC). There is no change over time with online for it is already on the batteries.

Overall, short change over does not affect most equipment (CCTV, basic computer equipment) , however online UPS is preferred for more expensive and sensitive equipment like servers and medical scanners.

Below is a diagram to demonstrate the difference between how a line interactive UPS “cleans the power” vs and online UPS. Please note if you are after a more technical diagram we do have this below.

comical description of line interactive vs online topology

Technical definition

Line-Interactive, during normal operation the mains supply is fed via an automatic voltage regulator (AVR) to feed the load. The AVR regulates the mains supply voltage, boosting if low or bucking if high. The mains supply is used to charge the batteries. When the AC goes out of the specified range, the load is switched to the inverter that draws its power from the batteries.

Online double conversion, converts the power twice, so during normal operation the mains supply is converted from AC to DC, the DC is then converted to AC that feeds the load. When the mains supply goes out of a specified range, there is no switching, and the UPS simply draws its power from the batteries.

image explaining line interactive vs online topology

Topology Comparison

Line Interactive Online Double Conversion
Normal Operation AVR supplies Load Inverter supplies load
Total Cost of Ownership Lower initial cost & Lower operating cost Higher initial cost                  & Higher operating cost                          (Energy & Heat generation)
Energy Efficiency during Normal Operation 96% – 98% 85% – 95%
Response to unstable or highly distorted mains supply Extreme voltage distortion can require frequent battery usage Accepts extreme voltage distortion without going to battery
Output Frequency regulation Output frequency varies within a range Output fixed to a configurable frequency
