The voltage monitoring relays from Schrack Technik will bravely safeguard your systems from overvoltage or undervoltage.
Stay in control of temperatures with our thermistor monitoring relays.
Monitoring relays from Schrack Technik are ideal for use in three-phase systems.
Quality is essential. The current monitoring relays from Schrack Technik are well worth their value.
Switch on and off after timed delays with the Schrack Technik timer relays.
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.
