Product Information
Product Overview
The PMDU is a 3-phase Multifunction Monitoring Relay with DPDT-NC contacts and cage clamp terminals. This PMD-series continuously monitors all voltages of a three-phase system. They are used to protect motors and equipment from expensive damage due to phase loss, phase reversal, phase unbalance, under-voltage and overvoltage faults as well as rapid cycling. These products detect single phasing and unbalanced voltages regardless of regenerative voltages. The PMD series incorporates a microprocessor-based design capable of advanced signal processing including True RMS voltage measurement. Innovative analog to digital sensing circuitry allows for true full-wave monitoring of all three phases, delivering the highest level of protection possible. True RMS voltage measurement ensures accurate sensing in most generator and other applications with non-sinusoidal wave forms, eliminating nuisance tripping.
- Mounts on 35mm DIN-rail
- Manual reset option works with external switch to reset the relay from outside the enclosure
- Full fault indication on top of unit for easy troubleshooting
