Datasheet

COO (Country of Origin):: DE

Detection of over- or under frequency of alternating voltage (adjustable function)

Fast reaction time by measuring duration of cycle of input frequency

Universal measuring input for AC-voltages of 15 ... 280 V as well as 30 ... 550 V

As option with measuring input for inverters

Adjustable hysteresis

Adjustable monitoring time for missing input signal at function over frequency

Response delay programmable via terminals 0 ... 100 s

Alarm storing or auto-reset programmable via terminals

Galvanic separation between measuring input, auxiliary voltage and output contacts

MH 9837 available with wide input range for auxiliary supply (AC/DC 24 ... 60 V or AC/DC 110 ... 230 V)

2 changeover contacts, closed circuit operation

Open circuit operation on request

LED indication for auxiliary voltage, measuring voltage and alarm status
