KRM161-DC monitors resultant insulation level between a non-grounded non-live DC network and its protective earth. The trip level is preset at factory and relay will operate when insulation is below trip level after a delay of 2-5 seconds. KRM161-DC unit injects a DC voltage signal into the monitored network and measure the earth leakage flow to the ground. Only one unit can be connected to each isolated system. Terminal 1 and 2 must be disconnected when network is powered. Features: -Insulation "megger" for non grounded non-live DC circuits -0-110VDC system voltage -"IDV" measuring principle -For use in land, marine and offshore for alarm-lamps, Lantern, DC motors etc. 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 .
