What is a Uninterruptible Power Supply (UPS)?


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

Tripp Lite's SMX1500LCD Line-Interactive Digital UPS System offers voltage regulation, surge suppression and long-lasting battery support for personal computers, network workstations, home entertainment systems and media centers. Internal UPS circuits support entry-level PCs for up to 60 min. or individual VCR/DVR components for up to 3 hours during power failures. Prevents data loss, viewing interruptions, lost recordings and loss of component programming. Automatic Voltage Regulation (AVR) circuits regulate brownouts as low as 176V back to usable levels without consuming battery power. Offers complete power protection in an attractive black tower configuration.
