Mitsubishi Drive Power Supply Board KCR-746A P203729B000G01

Mitsubishi Drive Power Supply Board KCR-746A P203729B000G01 is a Mitsubishi elevator PCB board used in drive-related control cabinet applications.

In the elevator spare parts market, this board may also be described as a Mitsubishi Elevator Drive PCB, Drive Board, Drive Power Board, W2 Board, or Elevator Driver Board. Several public supplier pages list P203729B000G01, KCR-746A, and KCR-745A together as Mitsubishi elevator drive PCB references.

For this type of Mitsubishi PCB, the printed board number is more important than the general product name. A buyer may call it a power board, drive board, W2 board, or driver board, but the final confirmation should depend on the original PCB label, connector layout, and elevator drive cabinet configuration.

Information Needed Before Ordering

To confirm the correct KCR-746A P203729B000G01 board, please provide:

• clear photo of the P203729B000G01 label
• KCR-746A or KCR-745A marking if visible
• front and back photos of the PCB
• connector quantity and position
• drive cabinet installation photo
• mounting hole layout
• original elevator model or controller cabinet information
• fault description or visible damaged area

This helps avoid confusion with other Mitsubishi KCR series boards that may look similar but serve different drive, power, or control functions.

Replacement Matching Reminder

Do not replace KCR-746A only by appearance.

Before installation, technicians should compare the old and new PCB carefully, especially:

• connector direction
• relay or power component layout
• board revision
• cabinet wiring
• fuse or protection circuit
• signs of overheating or short circuit

If the old board was damaged by external wiring problems, unstable cabinet power, or a drive circuit fault, replacing only the PCB may cause repeated failure.

For overseas buyers, sending complete board photos is usually the fastest way to confirm whether the required board is P203729B000G01 KCR-746A, KCR-745A, or another Mitsubishi drive PCB version.
