Medha offers HEP units from 300kVA-500kVA and higher (1000kVA – 2x500kVA), utilizing capacities of alternator / transformer to meet auxiliary power requirements such as lighting, fans, HVAC, heating, battery charging etc. of complete train. HEPs are IGBT based converters, using sine filters at inverter output to minimize harmonic distortions. Protections for output overload, short circuit and power ground are provided. The converters are designed to suit wide range of inputs.
