  • Voltage Monitoring Relays

    This is the end of uncontrolled voltage: Effectively ban the overvoltage threat with voltage monitoring relays from Schrack Technik. Attached you find our Online Shop products:

Safeguard your equipment with voltage monitoring relays for one-phase or three-phase AC systems. They protect your appliances from overvoltage. Overvoltage generates heat which may damage the more sensitive components in your appliances. Undervoltage may cause a voltage range that is undefined (for your equipment), which may result in an uncontrolled failure of individual components. The Schrack Technik voltage monitoring relays are built to safeguard you against these particular threats.

Overvoltage Monitoring

If the measured voltage exceeds the maximum allowed value, the tripping delay time starts to run. As soon as voltage values return back below the defined level, the relays close again.

Undervoltage Monitoring

If the measured voltage falls below the minimum allowed value, the tripping delay time starts to run. As soon as values return back above the defined level, the relays close again.
