Mitsubishi Elevator Drive Boards KCR-943A-942A-945A-946A-940A-944B KCR-94W1BC

Mitsubishi KCR-942A is a dedicated drive control PCB (VVVF/IPM drive board) for Shanghai Mitsubishi ELENESSA and LEHY machine-room-less elevators, serving as a core component of the main control system. It receives main control signals, drives IGBT inverter modules, and controls traction machine start/stop, speed regulation and torque output. Integrated with multiple protections including overcurrent, overvoltage, overheat and undervoltage, it ensures stable elevator operation, precise leveling and fast response.

The board features multi-channel communication interfaces and signal detection loops, compatible with KCR-943A, KCR-944C and other same-series drive boards for direct replacement and upgrade. Adopting high-density SMT technology with strong anti-interference and high stability, it is widely used in new elevator assembly, modernization and fault repair, acting as a critical PCB component for Mitsubishi machine-room-less elevator drive systems.
