Macromatic PMD Series - Phase Loss, Reversal, Unbalance & Under/Over Voltage Monitor Relays (Surface-Mount)     The PMD Series Phase Monitor Relays utilize a microprocessor-based design to provide protection against phase loss, phase reversal, phase unbalance, undervoltage and overvoltage. The PMDU is a universal voltage product that works on any three-phase system voltage from 208-480V (separate 120V & 575V versions are available). These devices are designed to be compatible with most Wye or Delta systems with no connection to Neutral required. PMD Series products protect against unbalanced voltages or single phasing regardless of any regenerative voltages. The relay is energized when the phase sequence and all voltages are correct. Any one of five fault conditions will de-energize the relay. As standard, reenergization is automatic upon correction of the fault condition. Manual reset is available if a momentary N.C. switch is wired to the appropriate terminals. A multicolor LED indicates normal condition and also provides specific fault indication to simplify troubleshooting. The PMD Series offers a variety of user-adjustable settings. The percent phase unbalance is adjustable from 2-10%, and also has a ..Disable.. setting for those applications where poor voltage conditions could cause nuisance tripping. The undervoltage drop-out can be set at 80-95% of operating voltage (overvoltage setting is fixed at 110% of nominal). The adjustable time delay drop-out on undervoltage (0.1-20 seconds) eliminates nuisance tripping caused by momentary voltage fluctuations. There is also an adjustable time delay (1-300 seconds) on both power up and restart after a fault has been cleared.     Features: Universal voltage range of 208- 480V on PMDU provides the flexibility to cover a variety of applications with one unit Protects against phase loss, phase reversal, phase unbalance, undervoltage and overvoltage Variety of user-selectable and adjustable settings for the ultimate in three-phase protection Automatic & Manual Reset in Same Unit Multi-Color LED indicates normal condition and provides specific fault indication to simplify troubleshooting 45mm DIN-style surface-mount case 10A SPDT & SPNC output contacts   Click here for specifications and dimensions in .pdf format  Part Number Protects Against Nominal Voltage (50/60 Hz) Phase to Phase (Line to Line) Wiring  PMD120 Phase Loss, Phase Reversal, Phase Unbalance, Undervoltage & Undervoltage 120V  PMDU Phase Loss, Phase Reversal, Phase Unbalance, Undervoltage & Undervoltage 208-480V  PMD600 Phase Loss, Phase Reversal, Phase Unbalance, Undervoltage & Undervoltage 575V These products come standard with one (1) SPDT & one (1) SPNC output. To order PMD units with a second N.O. contact instead of the N.C. (terminals 21- 22), add a suffix ..-A1.. to the Product Number, i.e., PMDU-A1 To order PMD units with DPDT output contacts instead of one SPDT and one SPNC, but with no manual reset feature, add a suffix ..-A2.. to the Product Number, i.e., PMDUA2.   Phase Loss: Unit trips on loss of any Phase A, B or C. Phase Reversal: Unit trips if rotation (sequence) of the three phases is anything other than A-B-C. Undervoltage: Adjustable from 80-95% of nominal voltage. Unit trips when the average of all three lines is less than the adjusted set point for a period longer than the adjustable time delay drop-out. Overvoltage: Fixed at 110% of nominal voltage. Unit trips when the average of all three lines is greater than the fixed set point for a period longer than the time delay drop-out. Phase Unbalance: Adjustable from 2 - 10% 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 . There is also a ..Disable.. setting adjustment that will turn off the Phase Unbalance Protection if nuisance tripping is a problem. Output Contacts: 10A SPDT & SPNC @ 240V AC/30VDC, 1/2HP @ 120/240V AC (N.O.), 1/3HP @ 120/240V AC (N.C.) Life: Mechanical: 10,000,000 operations, Full Load: 100,000 operations Response Times: Power Up & Restart After Fault: 1 - 300 seconds adjustable Phase Loss & Reversal 100ms fixed Phase Unbalance 2 seconds fixed Undervoltage 0.1 - 20 seconds adjustable Overvoltage Fixed Time Based on Inverse Time Curve Hysteresis: 2-3% Load (Burden): Less than 3VA Temperature: -28° to 65°C (-18° to 149°F) Mounting: Does not require a socket. Can either be mounted directly on 35mm DIN track with no additional parts or to a back-panel with Panel Mounting Kit (supplied) & two screws Reset: As standard, reset is automatic upon correction of fault. When a momentary-contact N.C. switch is wired across the Manual Reset terminals (M1 & M2), the unit switches to manual reset mode and remote manual reset is available.
