MTM Power GmbH, the specialist for high-quality power supplies, offers in its programme DC/DC converters of the series HVC with 150W and 250W for railway applications. 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.
