Murphy BCES-12-5 Specifications

Battery Chargers – Sentry and Guardian Models
The Sentry and Guardian battery chargers provide automatic, current limited and voltage controlled
charging to vented lead acid batteries. They may be used in a wise range of industrial charging
applications, including standby engines, pumps and generators.
Each unit consists of a transformer, rectifier and thyristor control circuit. The control circuit ensures that
the charger maintains a battery voltage at the pre-calibrated float level, while supplying any additional
load current up to the specified maximum.
