The BCP 150 has a low battery disconnect circuit to prevent damage to the battery by low discharge during prolonged AC failure. The battery input is also protected against accidental reverse battery connection by a crossbar diode and internal safety fuse. It has an AC/Charger Fail Alarm to indicate either failure of the charger circuit or loss of AC input power. A charger ‘ON’ LED indicator is located beside the terminal block.
Cooling is via baseplate to a heatsinking surface and by natural convection, and the unit is rated for operation over a 0 oC to +50oC cold plate temperature for full specification. An extended temperature range is available on request. The charger is ruggedized to meet IEC61373 Cat 1 A&B requirements as a minimum, with heavy ruggedizing and conformal coating available for operation in extreme environments. It is fully protected and meets EN 60950-1 and related standards. Low component count, large design headroom, and the use of components with established reliability result in a high MTBF.
