Medha offers a wide range of Auxiliary Converters for all types of rollingstock; Locomotives, Electric Multiple Units, Diesel Electric Multiple Units, Monorail, Light Rail, and Special Rail Vehicles.
Auxiliary converter plays a crucial role in managing and supplying electrical power to various onboard systems and subsystems that require low-voltage AC or DC power. Auxiliary converters need to incorporate energy-efficient designs, as their continuous operation can significantly impact the overall energy consumption of the train.
Common auxiliary loads consists of a mix of blowers, pumps, compressors, lighting, fans, HVAC systems, battery charging, and auxiliary power needed for other subsystems.
Medha’s auxiliary converters are state of the art, highly efficient, robust, versatile, customizable, and compliant with EN and IEC industry standards, making them being preferred converter globally for various rail applications.
