BORIS is a fast transfer line-interactive
uninterruptible power supply. It is designed
to prevent blackouts, brownouts, sags, swells
and surges from reaching the protected load
under normal conditions. It filters out small
utility line fluctuations and isolates the
protected load from large disturbances by
internally disconnecting from the utility line,
while supplying power from its internal
batteries until the utility line returns to
normal.
While operating on battery, an internal
alarm will intermittently beep. The ON/TEST
button may be pressed to silence the alarm.
If the line utility does not return and the
battery continues to power the protected load,
a low battery shutdown may occur.
Advance warning of a low battery condition
begins approximately two minutes before the final shutdown. This alarm will be a
continuous beeping sound and cannot be silenced. Normally this condition should not occur
(if batteries were previously charged fully) due to remote shutdown capability of BORIS and
Virginia Controls’ controller.
Special features include surge protection; EMI/RFI filtering, high and low voltage
correction (without draining batteries), as well as automatic battery testing during power up
and every 14 days thereafter. User-replaceable batteries can be replaced without having to
remove power from the loads.
