Battery Charger Operation
The Trace UR-UPS is equipped with a three-stage
battery charger.
The batteries receive different charge voltages and
currents, depending on the charger mode. After a utility
grid failure, the charger automatically cycles through the
charging modes. When charging is complete, the
batteries receive a maintenance charge to keep them in
a fully charged, ready state.
BULK
Bulk is the initial stage of charging. In this mode, the
charger’s maximum constant current is supplied to the
batteries. The CHARGE LED flashes once per second to
indicate bulk charge mode. Over time, the battery
voltage rises until the bulk voltage setting is reached
(14.3 Vdc for gel batteries and 14.7 Vdc for liquid
batteries). The charger then switches to absorption
mode.
During this stage of charging, the automatic cooling fan
will be typically running.
ABSORPTION
The charger supplies a constant (bulk) voltage to the
batteries as the charge current is slowly reduced. The
CHARGE LED flashes rapidly (10/sec) during the
absorption stage, lasting approximately 1 hour.
During this stage of charging, the automatic cooling fan
will be typically running.
FLOAT
During the final stage of charging, the batteries are held
at the float voltage (13.6 Vdc for gel batteries and 13.4
Vdc for liquid batteries). This reduces battery gassing,
minimizes watering requirements (for liquid batteries)
and ensures complete battery charging.
The CHARGE LED is ON solid while float charging.
Note: Charging
efficiency is
directly related to
the quality of the
input AC
waveform.
