  • Page 4: Product Function

    The BCDC1212T is a three-stage, 12 V DC-DC battery charger that operates from an alternator input of 12 V or 24 V. The input voltage to the BCDC1212T can be above, below or equal to the output voltage making it ideal for charging an auxiliary 12 V battery where the distance from the start battery or alternator may cause a significant voltage drop.

  • Page 11: Wiring

    INSTALLATION Wiring The heavy gauge wires on the BCDC1212T unit carry peak currents of up to 25 Amps, and it is important to make good, low resistance, electrical connections that will not degrade over time. Failure to make a good, reliable contact may result in breakdown of the wire insulation and cause a short circuit, or worst case a fire.
