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;
– overvoltage protection at input;
– overtemperature protection.
