The insulation monitors MK 5880N and MH 5880 of the VARIMETER IMD family provides best insulation monitoring of pure three-phase and AC IT systems in a state of the art way fulfilling the relevant standards. The adjustment of the setting values is simple and user friendly done on 2 rotary switches on the front of the device. The MH 5880 also has a galvanic separated analogue output and a 11 step LED chain for display the actual insulation value.

Features

For single and 3-phase AC-systems up to 0 … 500 V and 10 … 1000 Hz
Monitors also disconnected voltage systems
Adjustable tripping value RAL of 5 … 100 kΩ
De-energized on trip
Auxiliary voltage, measuring circuit and output contacts are galvanically separated
Manual and auto reset
With test and reset button
Connections for external test and reset buttons possible
LED indicators for operation and alarm
2 changeover contacts
MK 5880N/200 with additional prewarning- Adjustable prewarning value 10 kΩ … 5 MΩ- 1 output relay for alarm and 1 for pre-warning
MH 5880/500: similar to MK 5880N but with galvanic separated analogue output and 11 step LED chain for the actual insulation value
