The devices are available with an input range of 420…1100 VDC (375…1125 VDC; t ≤ 2 s), an isolation up to 8 kVAC and the standard output voltage of 24 VDC. With the high voltage converters it is possible to supply electronical equipment out of 600 V / 750 V contact wire. The DC/DC converters are used for supplying points, signal lamps and electronic monitoring of the rail net. The specific feature of the series HVC is its use as a self-starting module for trams or trolley buses with exhaustive discharged batteries so that the towing process can be avoided.
