Your source for phase monitors including phase loss and phase sequence, voltage monitors including over- and under- voltage, over- or under- current monitoring, 3-phase load guards, 3-phase monitor, phase monitor, monitoring relays.

If the electrical parameters are in control everything runs correctly, reducing downtime and maintenance costs.
These monitoring controls will help you achieve this!

Single Function:
Reacts when the setpoint is eclipsed or for major failures (i.e. phase sequence or loss).
Applications: correct motor rotation direction, ON/OFF current monitoring, motor overtemperature

Extended Function:
Adding time delay, more ranges, RMS measurement and more.
Applications: monitoring mains quality, motor overload, generator speed, pump dry running

Full Function:
For complete monitoring, two setpoints two relay outputs.
Applications: full mains monitoring, sophisticated current and voltage monitoring, full generator parameters Marshall Wolf Automation offers a full line of monitoring controls, if you do not see what you need please contact us and we'll find it!
