General Advice

An Uninterruptible Power Supply (UPS) is a device that maintains power to PCs, servers, network equipment, audio/video equipment and computer peripherals during short power outages, and allows computer systems to safely shutdown during prolonged blackouts. UPS Systems also stop damaging power surges and filter disruptive line noise, while select models correct brownouts and over-voltages.
