The digitally controlled KPM169 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. Features: -Direct connection 12 to 48 VDC systems, up to 1600VDC with RH adapter -Precision reading unaffected of system voltage -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/L-version) Borna niroo karan company (Brnika) is Exclusive Representative of Megacon , in the purchase, sales, consulting and distribution and industrial equipment and measurement equipment, including Insulation Monitoring and so is active .
