The insulation monitor RN 5897/320 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, that need an extended temperature range. The connection to the monitored voltage system is done via one of the coupling units. The setting of the parameters and the switching values is done by simple and operator friendly rotational switches on front of the device. The operating status is indicated user friendly via a multicolour LED. With a sealable transparent cover the device is protectet against manipulation.

Features

  • 2 separate adjustable response thresholds (using e.g. for pre-alarm and Alarm)
  • Setting range of 1st response value (Pre-alarm): 20 kΩ … 500 kΩ
  • Setting range of 2nd response value (alarm): 1 kΩ … 100 kΩ
  • 1 changeover contacts each for insulation failures-Pre-alarm and -alarm
  • Energized or de-energized on trip can be selected for indicator relay
  • With multicolour status LED to indicate the state of operation.
  • Automatic and manual 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
  • 3 wide voltage input for auxiliary voltage
  • Additional coupling device is necessary
  • Width 52.5 mm
