What is a Uninterruptible Power Supply (UPS)?

TRI SMX1500LCD5

An Uninterruptible Power Supply (UPS), is an electrical apparatus that provides emergency power to a load when the input power source, typically mains power, fails. It will provide near-instantaneous protection from input power interruptions, by supplying energy stored in batteries. The on-battery runtime of most uninterruptible power sources is relatively short (only a few minutes) but sufficient to start a standby power source or properly shut down the protected equipment.

At H&H Audio Visual we will sometime recommend the use of a UPS with equipment (NAS (network attached storage) drives, PVR,s CCTV DVR recorders) where an unexpected power disruption could cause disruption, data loss, viewing interruptions, lost recordings and loss of component programming. Tripp lite UPS
