Redarc BCDC-1206 User manual

BCDC-1206
3 Stage DC-DC Battery Charger
FUNCTION
The BCDC-1206 is a three stage 12V DC-DC battery charger that operates with an input of between 9 and
32V. The input voltage of the BCDC-1206 can be above, below or equal to the output voltage making it
ideal for charging an auxiliary 12V battery where the distance from the main battery may cause a significant
voltage drop. The wide operating voltage range provides a simple solution to charging trailer mounted bat-
teries. The BCDC-1206 can deliver sufficient current to charge a battery that has a typical DC compressor
fridge connected.
When the BCDC-1206 is turned on it will start in Boost mode, Boost mode maintains a constant current
until the battery voltage reaches 14.5V. The charger will then convert to Absorption mode, maintaining the
voltage at this level for a predetermined period of time; after which it will enter Float mode. Float mode
maintains 13.7V on the battery being charged until a load on the battery causes the battery voltage to drop
below 12.2V when it then re-enters Boost mode.

INSTALLATION
The battery charger should be mounted as close as practicable to the battery being charged. To minimise voltage
drop, ensure all additional wiring, especially from supply, is of adequate thickness. Appropriate sized fuses must be
used to protect the unit from reverse polarity connections; without said fuses, the unit will be damaged in the event of
a reverse polarity connection. The ignition connection is supplied to allow the unit to be switched by a low current
positive source of between 9 and 32V. For continuous operation, the ignition input can be connected directly to the
supply input.
