Galvanic Isolation Module with Insulation Monitoring MGR PN Model for Safety Applications

Module of galvanic isolation with insulation control MHD is designed to provide galvanic isolation of power supply circuits of consumers (automation, signalling and lighting devices) in underground mine workings of mines and mines, non-hazardous by gas or dust, according to the marking, GOST 24754-2013, GOST 30852.20-2002 with control of power supply quality parameters, control of power supply circuits isolation and protection against short-circuit and overcurrent. MGR is included in power supply schemes of three-phase alternating current with nominal operating voltage of 380 V without neutral. The MHD is equipped with a monitoring module performing tele-signalling functions. MGR has mine normal execution in accordance with GOST 24754-2013 and insulation level PH1 in accordance with GOST 30852.20-2002.
