BCH300-500 Series

AC/DC Power Supply | Battery Charger 300W – 500W

The BCH300 & BCH500 series battery charger is a rugged, industrial-grade product, using field-proven design suitable for use in DC battery back-up applications. It is a mature product providing excellent reliability and performance and delivering 300 / 500 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
