ATC Diversified Electronics SLA Phase Voltage Monitors
ATC Diversified Electronics SLA Phase Voltage Monitors are designed to protect 3-phase equipment against phase loss under voltage and phase reversal conditions. The internal relay will energize (PICK-UP) with standard operating voltages applied in the proper ABC sequence. The relay will de-energize (DROPOUT) when an incorrect phase sequence or phase loss occurs or the three-phase voltages fall below the dropout voltages. Both Wye and delta systems may be monitored, and connections to neutral are NOT required in the Wye systems. These SLA phase monitors offer A, E, and N styles. The SLA phase monitors feature fixed, lock shaft or screwdriver adjustments and several enclosure styles. These SLA phase voltage monitors operate at 480V switching voltage, 10A contact current rating, and 32ºF to 131ºF temperature range. The phase monitors are ideally used for air handlers, computer power protection, robotics equipment, elevator drives, and conveyor drive.Features
