What is a UPS?
An Uninterruptible Power Supply is a device that sits between a power supply (e.g. a wall outlet) and a device (e.g. a computer) to prevent undesired features of the power source (outages, sags, surges, bad harmonics, etc.) from the supply from adversely affecting the performance of the device.
Can I install the UPS equipment myself?
Many of the smaller “Plug and Play” devices available, which operate in the 650 VA (Volt Amps) to 3000 VA range, can be installed by a computer owner / administrator without the need for a qualified electrician or IT / UPS specialist. If you have a larger installation, however or need any advice on your UPS installation, then please get in touch.
How long can equipment on a UPS keep running after the power goes?
That depends on how big a UPS do you have and what kind of equipment it protects. For most typical computer workstations, a UPS that is rated to keep the machine alive through a 5 minute power loss is often adequate, just enough time for the critical IT devices to shutdown using the shutdown software.
If it is important for a machine to survive hours without power, then a more robust power backup solution, including a generator and other components will be needed.
Why do UPS systems need regular servicing?
The critical nature of UPS systems means that they need to be serviced regularly to ensure that the internal workings of the units and their batteries are functioning correctly.
A carefully structured UPS maintenance programme can safeguard your business against faults and expensive ad hoc repairs, whilst maximising the working life of the UPS.
When does a UPS system generally need replacing?
A UPS system should be replaced when it is at the end of its lifespan and beyond economical repair or when the efficiency savings demonstrated by a new unit outweigh the existing running costs.
The typical lifespan of a UPS unit is 10 years, during which its internal batteries will need to be replaced up to three times. Using comprehensive efficiency reports to highlight the savings a new UPS with up-to-date technology could provide, often it is more economical to change your UPS before its lifespan is reached.
