The LP-1 becomes an
uninterruptable power supply when
used with a transformer and battery. The
output of the LP-1 is a clean smooth continuous DC power which can be
used to
power the most sensitive electronic controls.
The
LP-1 output and battery charge voltage is selected by
moving the programming jumper to 6V, 12V or 24V. The voltage
selected is factory preset to
precisely charge a Sealed, Liquid, or Gel Type Lead Acid Battery(s). The
current that the battery draws from the LP-1 is
determined by the battery's condition, capacity, temperature and state
of
charge. The LP-1 is protected against
shorts and overloading with its electronic circuitry and battery
fuse.
This same circuitry also protects the
transformer. When the DC load requires
more than the maximum output provided by the LP-1, the battery can add
up to 4
more amps. This may be necessary
to sound a high powered siren for
the duration of an alarm. The LP-1 has a
replaceable 4 amp battery fuse or optional automatic resetting 4 Amp
circuit
breaker.
For
calculating standby current, recharge times, and
available current, refer to the tables and the specifications on the
backside
of this bulletin.
To
test the battery and fuse: It is recommended that on a
regular basis, the output should be checked for proper voltage and
current
while the AC power is removed.
