Tax included

The three-phase monitoring relay DUW-41 monitors

the three-phase mains for overvoltage and undervoltage, the correct phase sequence as well as for failure of a phase .

The device is supplied by the measuring circuit L1 – (N)

– L2 – L3. The output relay is pulled up in normal operation. The output replay drops out at overvoltage or

undervoltage, failure of a phase and phase sequence

violation. The error is displayed by the red LED. In order

to bypass brief mains faults, the off time t can be delayed by 0.5 to 10 seconds with the potentiometer
