ISOMETER® IR123P
- Insulation monitoring device for mobile generators
- Protective separation with insulation monitoring and disconnection
- According to IEC 60364-5-55 and IEC 61557-8
- Optocoupler output for signalling the device status
- Galvanically separated PWM output for the measuring value
The ISOMETER® IR123P monitors the insulation resistance RF of an unearthed AC system of 100...300 V against earth, that is supplied by a mobile generator according to DIN VDE 0100-551. The IR123 is suitable for AC systems with operating frequencies of 22...65 Hz as well as for AC systems including DC components. The maximum permissible system leakage capacitance Cemax is 5 μF.
