An Uninterruptible Power Supply provides an emergency back-up power source in the event of the mains supply either failing or dropping. There are several reasons why you may need back-up power - notably a break in the electricity supply or hardware failure. Either event can be catastrophic if you are using your PC or running a server. But a UPS that kicks in immediately can prevent any damaging loss of data.

UPS provides essential back-up
Uninterruptible power supplies are essential for the reliable operation of servers, as well as computers in applications like data centres, hospitals and other locations where even a momentary loss of power can cause plenty of damage.
How a UPS works
The UPS takes its power from the mains supply which effectively charges its battery. When the mains power is cut the UPS switches to battery mode to feed power to the connected devices. The UPS can only feed power for a limited time but provides back-up until either the original power source is restored or a new source plugged in.
Find everything you need at Ebuyer
If you are looking for a new Uninterruptible Power Supply we have both rack mounted and tower systems. You can also find all the extras you need including batteries and power distributor units. And don't forget to check out our range of UPS accessories including surge suppressors, cable organisers and extended run enclosures.
You will find great deals on all our UPS products and if you order today before 11pm we can deliver your items tomorrow (terms and conditions apply).
