Uninterruptible Power Supply (UPS) systems provide protection to IT equipment from mains spikes, over voltage, brown outs and complete power failure. All our hire UPS systems are full online models that regenerate 240VAC 50Hz clean sine wave from internal batteries 100% of the time.
Why would you rent a UPS? An uninterruptible power supply will provide protection to delicate mains powered equipment from a variety of potentially damaging power issues. Our UPS systems have been deployed on vessels, rigs and other offshore structures as well as remote locations where power is supplied by portable generators such as televised major golf championships.
Complete mains failure will result in computers and servers switching off. However if the operating system is completing certain tasks data can be lost and at the worst case, the operating system can be corrupted. An online UPS output will be completely unaffected by a blackout with mains supply provided from batteries allowing controlled power down of computers and servers.
Spikes are a dramatic short lived increase is voltage which can be caused by electrical storms, fallen power lines. Spikes can cause data corruption on hard drives, computer crashes and even equipment damage.
Power surges are sort term voltage increases on the mains supply normally caused by switching off of high power equipment such as air conditioning units or industrial motors. Power surges will permanently damage computers and other delicate IT equipment – bang!
Brown Out and Sag
Brown outs and Sags are a decrease in mains voltage caused by demand outstripping supply such as the switching on of high power equipment that the supply cannot deal with. Brown outs and Sag will cause computer crashes and data corruption as well as potentially damaging varying internal voltages if cheaper power supplies are in the PCs.
