Description
Product Description:
The ALC12DE-010-1312 is a traction converter module (inverter) from Alstom’s ALC12DE product family. It converts DC link power from the overhead catenary or third rail into controlled three-phase AC power for driving Alstom traction motors. This unit is used in modern EMUs and locomotives with Alstom ONIX or AGATE control platforms.
