ACM (Auxiliary Converter Module)

The auxiliary power module converts 1500 VDC or 750 VDC line voltage into three-phase AC voltage intended for supplying the train’s air-conditioning unit and compressors, single-phase AC voltage for lighting and service purposes, and DC voltage intended for charging batteries and supplying control equipment. This module converts DC input voltage into 380 VAC and 110VDC for the aforementioned purposes.

Auxiliary converters for subway trains are designed to be an efficient and highly reliable power supply. JDEVS designs and manufactures auxiliary converter systems which are compact and light for the entire range of supply voltages.
