UPS Systems


An Uninterruptible Power Supply (UPS) is an electrical apparatus that provides emergency power to a load when the input power source, typically your utility power, fails. A UPS differs from an auxiliary or emergency power system or standby generator in that it will provide near-instantaneous protection from input power interruptions, by supplying energy stored in batteries or a flywheel. The “on-battery” runtime of most UPS systems are relatively short (only a few minutes) but sufficient to start a standby power source or properly shut down the protected equipment or load.

A UPS is typically used to protect computers, data centers, telecommunication equipment or other electrical equipment where an unexpected power disruption could cause injuries, fatalities, serious business disruption or data loss. UPS units range in size from units designed to protect a single computer to large units powering entire data centers or buildings.

The primary role of any UPS is to provide short-term power when the input power source fails. However, most UPS units are also capable in varying degrees of correcting common utility power problems such as voltage spikes, brown outs, frequency transients, and harmonic distortions to name a few.

There are several technologies in use when considering a UPS system. Other considerations include the environment, the amount and type of load, redundancies, physical size considerations, typologies, etc.

Since Guardian Power works with multiple manufacturers, we can specify the right UPS for your application to meet your current and future needs. This distinction has great advantages for our customers. It allows Guardian Power to be completely objective and unbiased in our recommendations and solutions. We are the customer’s advocate and not necessarily the manufacturers.
