Brand: ALSTOM Rail Transport (formerly Mitrac Traction Platform)
Complete Model: 3EST125-975 Board Assembly, Part Number DCC2382A
Category: Onboard Traction Inverter IGBT Driver Main Control Board (Core Signal Board Inside TCU)
Application Scenario: Subway, urban rail, and legacy Mitrac traction inverters in locomotives; responsible for IGBT pulse driving, hardware overcurrent/overvoltage protection, and power circuit sampling feedback
Hardware Features: Isolated driver optocouplers, short-circuit detection, gate drive amplification, fault self-locking, and onboard wide-temperature design (-40°C to +85°C)
Series Compatibility: DCC2382A/B/C are hardware iteration versions with identical structure, interfaces, and end-of-life cycles

Application
Machinery plants: configure operating parameters for automated machines and CNC equipment
Food plants: display the status of filling lines and mixing machines
Packaging plants: operate control interfaces for packing, sealing, and labeling machines
Pharmaceutical plants: monitor process data for mixing reactors and packaging lines
Electrical control plants: assemble operator panels for low-voltage switchboards and pump control cabinets
