Operation

AC Current Sensing

The CSR generates its own operating power supply from the monitored current line. No external power supply is needed. A current greater than the pick-up current is required to energize the output relay. The output relay will stay energized until the current in the line being monitored drops below the drop-out current level for the CSR.
