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 batteries.The BCDC-1206 can deliver sufficient current to charge a battery that has a typical DC compressorfridge connected.When the BCDC-1206 is turned on it will start in Boost mode, Boost mode maintains a constant currentuntil 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 modemaintains 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.
