Page 4: Product Function
PRODUCT FUNCTION The BCDC2420(-LV) is a three-stage, 24V DC-DC battery charger that operates from an alternator input of 12V nominal or a 12V nominal solar panel input. The BCDC2420 will also charge from an alternator input from a 24V nominal vehicle* . -
Page 5: Charging Algorithm
PRODUCT FUNCTION Charging Algorithm When the BCDC2420(-LV) is turned on, it will move into the Boost stage. The Boost stage maintains a constant current until the battery voltage reaches the Absorption Voltage. The current during Boost stage may vary throughout operation in order to maintain a safe operating temperature, or to limit the difference between input and output voltages. -
Page 6: Error Codes
NOTE: Appropriate connections must be made to the wires with a continuous current rating of at least 20A for the BCDC2420(-LV). Failure to do so may cause damage to the unit and vehicle. -

Page 14: Frequently Asked Questions
The BCDC2420(-LV) will turn OFF for a split second every 100 seconds to measure the unloaded voltage at the battery. When the BCDC2420(-LV) turns off it is not drawing any load from the start battery, no load means that there is no voltage drop over the cable run. This allows the BCDC2420(- LV) to measure the actual battery voltage, or the voltage at the battery. -
