The devices are available with an input range of 400VDC to 975VDC (375VDC to1125VDC; t = 2 s) and the standard output voltage of 24VDC and 36VDC. With these high voltage converters it is possible to supply electronical equipment out of 600V / 750V 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. The rugged design together with high-quality components guarantee the high reliability in vehicles even under severe shock and vibration conditions. The high efficiency of 83 % and the dimensions of 330mm x 170mm x 87mm allow an operation without forced ventilation. Moreover the converters work with an ambient temperature range from –40°C to +85°C acc. to EN 50 155.
