The insulation monitor RN 5893 of the VARIMETER IMD family is a solution for optimal insulation monitoring of modern IT systems. The device can be used in the most flexible way for AC, DC and AC/DC systems. Mains areas of applications are non-earthed DC charging stations for electric vehicles with mains voltages up to DC 1000 V. The adjustment of the setting values is simple and user friendly done on 2 rotary switches on the front of the device. Via display and LEDs the measured value, device parameters and device status are indicated easy to read. With a sealable transparent cover the device is protectet against manipulation. The RN 5893 has an additonal Modbus RTU-interface. All measured values, device states and parameters can be read out, set and parameterized. All functions available on the device can also be operated via Modbus.

Features

  • Insulation monitoring according to IEC/EN 61557-8
  • 2 separate adjustable response thresholds (using e.g. for pre-alarm and alarm)
  • Setting value pre-alarm: 1 kΩ … 500 kΩ
  • Setting value alarm: 1 kΩ … 500 kΩ
  • Energized or de-energized on trip can be selected for indicator relay
  • Display for indication of measured value, device parameters and device status
  • Manual device self-test (automatic device self-test)
  • Alarm storage selectable
  • Protection against manipulation by sealable transparent cover
  • External control input for combined test- / reset-button with additional Stop of the measuring function
  • 2 wide voltage input for auxiliary voltage
  • Width 52.5 mm
