Getting the most from your UPS

Effectiveness, Efficiency and Longevity

It doesn’t matter if you’re a one man band or a multi-national organisation, your emergency power strategy could mean the difference between ensuring seamless and uninterrupted continuity of operations and losing precious data resulting in systems failure and loss of revenue during a mains power failure.

With an emergency power protection strategy from NSSE in place you will always have essential back-up power in such an event.

The key to getting the most from your power protection system is simple –

  • Ensure the system is Effective.
  • Ensure the system is Efficient.
  • Ensure the systems Longevity.



Uninterruptible Power Supplies are designed to do 2 things –

  1. Provide a regulated clean supply of electricity to your critical load.
  2. Ensure uninterrupted continuity of operations in the event of mains power loss.

Having an effective system is the easiest of our 3 steps to follow for your power protection strategy.

All that is required to determine the solution are 2 key components – your critical load (whether that be your I.T. Server, phone systems, emergency lighting or an entire floor) and an Uninterruptible Power Supply.

We take the relevant information relating to the equipment you intend to protect and appropriately size a solution determined by the critical load (your equipment) and desired autonomy (run-time). All you need to know is that when you encounter a mains fail (power cut) your UPS solution keeps you up and running with no interruption to your business.

As part of this power protection solution, our UPS systems will not only provide emergency power back-up allowing continuity of operations but will also ensure a regulated and ‘clean’ supply of power at all times. It does this by ensuring a consistent quality of power supply regardless of disturbances in the incoming mains. The output voltage is entirely regenerated by a sequence of AC to DC conversion followed by DC to AC conversion in order to create power supply without any electrical interference.

The result is a regulated, clean supply of power to your critical load.



Having an efficient UPS solution is nearly as important as having a solution at all.

The UPS system must be sized correctly so that operationally, it is providing optimum efficiency and protection whilst being cost effective through not only it’s TCA (total cost of acquisition), but it’s TCO (total cost of ownership) too.

An older UPS system will have a greater power input requirement whilst outputting less but generating more heat that it’s modern day counterpart. Output efficiencies in a modern day UPS also mean that a system running at .9pf can be sized smaller than a 10 year old unit running at .7pf.

Aside from the obvious cost saving in procuring smaller UPS systems and saving on footprint space, ongoing reduced costs are also realised (indirect energy costs such as reduced cooling required from air conditioning through less heat output).

This all contributes to marked reductions in your energy bills.



Once the right UPS solution has been procured and installed it is important not to forget about it and leave it to gather dust in the corner.

Regular maintenance will ensure the systems longevity and looked after properly, it should ensure that your critical load is completely protected for many years to come.

NSSE’s bespoke Maintenance Contracts allow for 1 or 2 service visits per year which will keep your UPS system(s) in tip top condition and highlight any issues and upcoming service works such as consumables replacements (batteries, capacitors and fans).

Batteries can (and should) be tested on a semi-regular basis by way of either load bank testing or via a controlled shutdown simulating a mains fail to confirm their performance. This will provide a definitive run-time figure in the event of mains power failure.

Our UPS battery solutions come with either 5 or 10 years design life.

Whilst 5 years is the desired period for which one would expect 5 year design life batteries to operate, the reality is that these batteries in all likelihood will last somewhere between 3 – 5 years depending on the number of cyclic charges, usage and operating environment.

Equally, you should expect to see around 7 to 10 years operational life for 10 year design life batteries. (Both of these figures can depend greatly on a number of variables).

The batteries ideal operating environment is between 20 – 23oC.

A well ventilated and air-conditioned environment is essential to the longevity of the batteries and well cared for systems can mean many thousands of pounds difference to any organisation’s maintenance overhead costs.

Increased temperatures and poorly ventilated environments can lead to premature degradation and even failure.

For every 10oC above the recommended temperature the batteries expected operational life is halved.

NSSE only provides battery solutions from the world’s leading battery manufacturers such as Yuasa, Fiamm and CSB so that we can afford peace of mind for all our customers.

Quality components are essential to the longevity and performance in any system, our UPS offerings ensure quality build, reliability and value for money.
