What is a UPS and why do I need one?


With Broken Hill’s power supply regularly experiencing outages, spikes or brown outs (voltage drops), it is highly recommended that computers and associated equipment like network switches and modems are connected to mains power via a UPS (Uninterruptible Power Supply).

A UPS performs several functions. Firstly, it acts as a backup power source providing power to equipment instantaneously when the mains power fails via an array of batteries which are kept charged when the UPS is under normal mains power operation. The amount of time the UPS is able to supply power to connected equipment is dependent on the power drawn by that equipment and the size or VA rating of the UPS. The higher the rating, the more power that is stored and hence the longer it is able to supply backup power.

Some UPS units will connect to a PC or server via a USB or Ethernet cable allowing it to communicate power status and other information. This means when a power outage occurs, the UPS can advise the system when it’s batteries are almost exhausted and the system will perform an orderly shutdown, minimising the risk of corrupted files and data loss. This often results when an abnormal shutdown occurs after a sudden power loss.

UPS units also perform a voltage regulation function, providing a constant power output to connected equipment during power spikes and brown outs. This again protects your equipment from damage and/or data loss.

A UPS is a relatively inexpensive way to keep your expensive IT equipment safe. If you would like more information on how a UPS can protect your systems, call or email us today.
