THE POWER SUPPLY MONITOR
   
For critical applications, Securitron offers the remarkable Power Supply Monitor as an accessory for its larger DC supplies. Available in 12 or 24 volt versions, the PSM can operate with all BPS series supplies with capacities of 2 Amps or more. The Power Supply Monitor functions as an alarm system for the supply as it monitors all key functions and reports any trouble. The output voltage is continuously read to insure that it remains within tight limits which are necessary for proper float charging of the battery pack. A high or low variance is separately signaled by audio/visual latching alarms at the PSM enclosure and simultaneous dry contact switching for remote notification. The PSM also checks the battery pack by taking it off charge three times a day and subjecting it to an extended load test. Failure is reported so that the pack may be replaced and naturally, the test is immediately teminated in the event of an actual power failure so that the load will continue to operate. Another important PSM report is whenever the batteries have switched in to the load. This provides vital warning that the load will continue to operate for only the standby duration of the pack. The batteries will switch in not only from an obvious facility power failure, but from a local AC breaker trip or a failure of the DC output of the supply. The PSM report always keeps your system working.
