The insulation monitor RN 5897/010 of the VARIMETER IMD family provides best and up to date insulation monitoring of modern IT systems in an optimum and state of the art way fulfilling the relevant standards. The device can be used in the most flexible way for AC, DC and AC/DC systems even with large leakage capacity to earth (PE). 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. Features • Insulation monitoring according to IEC/EN 61557-8 • Trigger output for insulation fault locating system • 2 separate adjustable response thresholds (using e.g. for pre-Alarm and Alarm) • Setting range of 1st response value (Pre-Alarm): 20 kΩ … 2 MΩ • Setting range of 2nd response value (Alarm): 1 kΩ … 250 kΩ • 2 changeover contacts für insulation failures-Pre-Alarm and -Alarm • Energized or de-energized on trip can be selected for indicator relay • Display for indication of measured value, device parameters and device status • Setting the maximum leakage capacitance to shorten the response time • Automatic and manual device self-test • Alarm storage selectable • Protection against manipulation by sealable transparent cover • External control input for combined Test-/Reset-button • 3 wide voltage input for auxiliary voltage • Width 52.5 mm Advantages / Customer benefit • Preventive fire and system protection • Detection of symmetric and asymmetric insulation faults
