PHASE LOSS, PHASE REVERSAL, PHASE UNBALANCE, UNDERVOLTAGE & OVERVOLTAGE PMPU-FA8X & PMPU-FA12X Series The PMPU-FA8X & PMPU-FA12X Series Three-Phase Monitor Relays continuously monitor all voltages to protect motors and equipment from expensive damage due to phase loss, phase reversal, phase unbalance, undervoltage and overvoltage. These products detect single phasing and unbalanced voltages regardless of any regenerative voltages. Utilizing an advanced microprocessor-based design allows true RMS voltage measurement with full wave monitoring. This provides a more accurate method to measure the voltages, regardless of load type or wave shape, and results in improved protection across more applications. Protects against phase loss, phase reversal, phase unbalance, undervoltage, overvoltage & rapid cycling Universal voltage range of 190- 500V—greater range that covers more global applications True RMS voltage measurement ensures accurate sensing across more applications Retains fault indication and continues monitoring all voltages even with a lost phase Full fault indication on top of unit for easy troubleshooting 5A SPDT/SPNO (PMPU-FA8X) or 5A DPDT (PMPU-FA12X) output provides isolated contact for alarm circuits with appropriate socket True RMS voltage measurement ensures accurate sensing in most generator and other applications with non-sinusoidal wave forms, eliminating nuisance tripping. Full wave monitoring provides a more accurate method to measure the voltages, regardless of load type or wave shape, resulting in improved protection across more applications. Unlike similar three-phase monitor relays, these products 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. The PMPU-FA8X & PMPU-FA12X Series are true universal products that work on a wide variety of adjustable line-line voltages to cover more global applications. All other settings for undervoltage trip point, trip delay, restart delay and unbalance trip point are fixed for ease of setup. Both these products offer more than the standard SPDT output contacts. An extra NC contact can provide an isolated output for alarm circuits. The PMPU-FA8X uses a standard 8 pin octal socket even with the extra contact, and the PMPU-FA12X uses a 12 pin square socket (see www.macromatic.com/fa8x). Operation: When the proper three-phase line voltage is applied to the unit and the phase sequence (rotation) is correct, the relay is energized after the Restart Delay is completed. Any one of five fault conditions will de-energize the relay. Re-energization of the relay is automatic upon correction of the fault condition. A bi-color status LED indicates normal condition and also provides specific fault indication to simplify troubleshooting.
