Overview
Power Supply MonitorThe PSM Power Supply Monitor module is designed to provide an AC power failure, DC power failure, load shed and low battery signal from an incoming AC power line and a 24 VDC or 12 VDC backup battery power supply.
Specifications
The PSM module is designed with standard plug-in solid state I/O modules to monitor the AC and DC power fail signals. A power monitor IC is used to generate the low battery signal along with the load shed signal.
