The voltage stabilizer IP-5
The voltage stabilizer IP-5
IP-5 is designed for electric power supply of lamp circuits and auxiliary equipment of mine trolley locomotives and converts DC voltage 250 V into stabilized constant voltage 24 V with load current 10 .
 
The voltage stabilizer IP-5 with the function of uninterrutible power supply
The voltage stabilizer IP-5 with the function of uninterrutible power supply

IP-5 (renewed) with no-break power function ensures:conversion of trolley system voltage into DC voltage 24V; independent power supply of on-board V-network 24V during the period up to 40 sec. after  pantograph bouncing; short circuit protection; peak overvoltage protection at input; blackout of block from the trolley system under voltage lower 130V and over 420V.
