MultiTek Reverse Power Relay

SELECTION GUIDE
M200-RP1 Single phase or 3 phase 4 wire
M200-RP3 3 phase 3 wire

TYPICAL APPLICATIONS
The M200 reverse power relay is used to monitor the direction of power from AC generators. If the current in the system being monitored is reversed, to a value greater than the customer adjustable pre- set limit, the relay will energise.
The adjustable trip point is 2 to 20% of input current. An adjustable time delay of 0 to 20 seconds is provided. Correct setting of the trip point and time delay will ensure protection against motoring in the event of a generator failure and prevent tripping due to transients encountered during synchronising.
A red LED indicates the state of the relay and a green LED indicates the condition of the power supply.
