BCH800 – BCH1K -RM

2U Rack Mount Battery Charger / Power Supply 800W – 1000W

The BCH800-1K series battery charger is a rugged, industrial-grade product, using field-proven design suitable for use in DC battery backup applications.It is a mature product providing excellent reliability and performance and delivering up to 1000 watts of output power with convection/conduction cooling NO Fans.

The two alarms provide external monitoring of Power Fail / Charger Fail and Battery Low via voltage free contacts.

The chassis-mount design feature allows for easy mounting.

Additional ruggedizing and conformal coating are available for applications requiring higher immunity to shock, vibration, humidity, moisture, dust and insects.
