Macromatic's PMD Series Three-Phase Monitor Relay continuously monitors all voltages of a 190-500V three-phase system. It is used to protect motors and equipment from expensive damage due to phase loss, phase reversal, phase unbalance, undervoltage and overvoltage faults, as well as rapid cycling. This product detects single phasing and unbalanced voltages regardless of regenerative voltages. Unlike similar three-phase monitor relays, the PMP Series will continue to function even with a lost phase. They are the only line-powered units in their class to retain fault indication and continuous monitoring of all voltages during a phase loss, increasing the ease of troubleshooting and the level of protection.
