The
Behlman RUPS-1250 Uninterruptible Power Source is a true
on-line UPS that continuously conditions incoming power and
provides a high quality sine wave output with very low distortion.
In the event of a loss of input power the RUPS will switch to
the internal batteries, in ZERO time, for a safe shutdown.
The
RUPS continuously monitors status, input, battery conditions,
fault conditions and alarms. This information is displayed on
the front panel and can be communicated to a host via a built-in
RS-232 interface and relay contact closures.
The
RUPS-1250 is a rugged, compact rack-mountable unit, with
hot-swappable batteries (from the front panel). The RUPS can
"cold-start" (start on DC) and has the ability to output a frequency
different from the source frequency. The RUPS-1250 is ideal
for remote and difficult-to-access locations. It provides conditioned
and back-up power for control, computer, instrumentation, communication
and other power sensitive equipment.
The
RUPS-1250 can be used anywhere in the world and is an
exceptional device for industrial and military ground, aerospace
and shipboard applications.
