Download Data Sheet

The BCD315 battery charger provides up to 300 watts to charge a 12 or 24 or 48 Volt battery system (1, 2 or 3 Banks) from a 24V, 48V or 72VDC source. The batteries must share a common ground but the source can be on a different positive or negative ground.

The all-new Current Mode switching design offers increased power and reliability in a compact package. The low ripple charging profile and standard equalize cycle greatly increases the lifetime of expensive battery systems. Extra input and output filtering reduce EMI to extremely low levels. Reliability features include an input fuse, thermal shutdown, current limiting, reverse battery hookup protection and output short circuit shutdown with automatic recovery.

Optional features include a Digital Volt/Ammeter, a Remote Control Panel, and/or a second Battery Temperature Sensor. We are confident that you will get many years of reliable service from this DC Battery Charger.
