Several types of Reverse Power Relays are available
including relays sensitive to reverse reactive power
(KVAR). WILMAR is the leading brand of reverse power
relays. Our rugged sealed construction provides con-
tinuous and reliable operation unaffected by shock,
vibration or other severe environments. Reverse Power
Relays are used for the protection of generator sets
operating in parallel.

available, see part number selection
Line Frequency ................................. 50-500 Hz.
Current Requirements ..................... 0 to 5 amp max direct or from CT with 5 amp
secondary
Trip Adjustment ............................... Screwdriver adjustable 4% to 20% (of the 5 amp rating)
Time Delay Adjustment .................... 0.5 to 20 seconds, screwdriver adjustable
Output Contacts ............................... One set N.O., one set N.C.
Contact Ratings ................................ 5 amp resistive at 120 AC or 28 Vdc
Power Consumption ........................ Voltage circuit: 2 VA max.
Current circuit: 4 VA max.
Notes:
1. Remove screw for access to the pick-up and time delay adjustments.
2. Clockwise rotation of the pick-up adjustment will raise the reverse trip point.
3. Clockwise rotation of the time adjustment will increase the time delay.
Consult factory for additional models.
4. Polarity of the voltage and the current connections must be observed for true power sensing.
5. Interchanging connections on terminals 5 and 6, will cause the output contacts to pick-up on forward power and dropout on no power or reverse power.
