Description

The BC1524 and BC3012 range provides fully automatic,
heavy duty charging of vented lead acid or NiCd batteries.
The chargers may be used in a wide range of industrial
battery applications, including standby engines, pumps
and generators.

The charger uses an open frame construction, designed
for surface mounting in an enclosed panel. Each unit
consists of a transformer, rectifier and control circuit.
The control circuit ensures that charger maintains the
battery voltage at the pre-calibrated float level, while
supplying any additional load current up to the specified
maximum.

A ‘boost’ operating mode can be used to provide increased
voltage output. Selection of normal or boost mode is via
three terminals, allowing activation by a remote panel
switch or time relay – see calibration table overleaf for
float and boost voltage levels.

A self diagnostic ‘charge fail’ circuit and relay output is
provided as standard. The volt free relay de-energises
in the event of a charging fault.

Power for the charger is from a 230VAC or 110VAC
supply (please specify at order). All electrical connections
are to stripped panel wiring via spring-loaded clamp
terminals.
