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.
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 xed 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 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
ve 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 specic fault indication to simplify troubleshooting.

RANGE

190-500V AC
(see below)
Three-Phase Line-Line Voltage:
Power Consumption: Less than 40VA.
Phase Loss: Unit trips on loss of any Phase A, B or C, regardless of any
regenerative voltages.
Phase Reversal (Out-of-Sequence): Unit trips if sequence (rotation) of the
three phases is anything other than A-B-C. It will not work on C-B-A.
Undervoltage: Fixed at 90% of the line voltage setting. Unit trips when the
average of all three lines is less than the adjusted set point for a period longer
than the xed 4 second trip delay. It will reset at +3% of the Undervoltage trip
setting.
Overvoltage: Fixed at 110% of the line voltage setting. Unit trips when the
average of all three lines is greater than the xed set point for a period longer
than the xed 4 second trip delay. It will reset at 107% of the line voltage setting.
Phase Unbalance: Fixed at 6% unbalance. Unit trips when any one of the three
lines deviates from the average of all three lines by more than the adjusted set
point for a period longer than the xed 4 second trip delay.
