For Operation At Contact Wire

MTM Power has released the HVC series of DC/DC converters with 250W for railway applications.

The devices are available with an input range of 420VDC to 1100VDV (375VDC to 1125VDC; t ≤ 2 s), an isolation up to 8kVAC and the standard output voltage of 24VDC.

With the high voltage converters, it is possible to supply electrical 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 HVC series’ special feature 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 and high-quality components guarantee high reliability in vehicles even under severe shock and vibration. The high efficiency of 88% and the dimensions of 330mm × 170mm × 87 mm allow an operation without forced ventilation.

Moreover, the converters work within an ambient temperature range from -40°C to 85°C according to EN 50 155.
