Product description
The frequency relays MK 9837N/5_0 e.g. MH 9837/5_0 are used for frequency monitoring of AC voltages. They are used for monitoring the output frequenc of frequency converters (/550) or for monitoring the rotor frequency of slip ring motors. Further area of application ist the monitoring of drives in crane systems.

Advantages
- Separate output signals for under and over frequency
- Simple wiring
- Easy handling
Features
- According to IEC/EN 60255-1
- Monitoring of AC voltage for under and overfrequency, can be used also for pre-warning (monitoring of AC voltage for under or overfrequency see datasheet MK 9837N)
- Separate relay outputs for over- or underfrequency (1 or 2 changeover contacts each)
- Alternative usage for monitoring of a frequency window
- Separate adjustment of response value for over- or underfrequency at 4 ranges each, 1.5 ... 200 Hz or 5 ... 600 Hz
- Second response value for prewarning possible
- 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
- Programmable hysteresis of response value: 2 ... 10 %
- Start up time delay programmable via terminals from 0 ... 50 s e.g. continuously
- Manual or auto-reset programmable via terminals
- Galvanic separation between measuring input, auxiliary voltage and output contacts
- MH 9837/508: With galvanic separated analogue output (current/voltage) and 11 step LED chain for the actual frequency
- MH 9837/5_0: With wide input range for auxiliary voltage available (AC/DC 24 ... 60 V or AC/DC 110 ... 230 V)
- Closed circuit operation (de-energized on trip)
