The digitally controlled KPM169C2x monitors insulation level between a non-grounded (IT) battery or live DC network and its protective earth.
Only ONE KPM169x can be connected to the same DC-system. An AC or DC (standard) auxiliary voltage is required for the unit. A green LED indicates AUX POWER on. Start of monitoring function is delayed when auxiliary power is switched on (default 2 secs delay). In this way false tripping during power up, caused by initial charging of network spread capacitance, is avoided.
During a Warning or Alarm condition the Polarity LED indicates the polarity causing the trip:
POSITIVE EARTH FAULT: LED not lit
NEGATIVE EARTH FAULT: blue LED lit
-Direct connection 12 to 48 VDC systems
-All inputs and outputs fully isolated
-Triple-zone insulation monitoring and Supervision relay
-"Pathfinder" function eases faultfinding
-Response time: 125-165mS
-Indicates polarity of dominant earth fault
-Analogue output proportional to meter reading (F-version)
