PSM Series 3-Phase Voltage Monitoring Relays

Teledyne Relays PSM Series 3-Phase Voltage Monitoring Relays safeguard equipment by automatically detecting phase loss, sequence issues, and undervoltage. These voltage monitoring relays provide power supply by the monitored mains for mounting on the DIN rail. The 3-phase voltage monitoring relays protect critical equipment from malfunctions, ensure consistent and reliable operation, and are easy to install. These relays operate directly from the monitored mains, eliminating the need for an additional power supply.
