• Drive Power Supply Board
• Power Board
• Drive Board
• Power Supply Board
• Elevator PCB Board
• KCR Series PCB

Because Mitsubishi KCR boards may serve different functions depending on the elevator system and cabinet configuration, the exact model printed on the original PCB should always be used as the main confirmation reference.

Information Needed Before Ordering

Before confirming the correct board, please provide:

• clear photo of the KCR-1140A / 1141A / 1142A / 1143A label
• front and back photos of the PCB
• connector quantity and position
• board size and mounting holes
• drive cabinet installation photo
• related Mitsubishi elevator system information
• visible damaged area or fault description

If the board label is not clear, photos of the complete drive cabinet and close-up PCB markings can help confirm the correct model faster.

Replacement Matching Reminder

Do not replace KCR-1140A series boards only by appearance.

Before installation, technicians usually compare:

• PCB model number
• connector direction
• board revision
• cabinet wiring
• fuse or protection circuit
• related drive or power module condition
• signs of overheating or short circuit

If the original board was damaged by an external drive circuit fault, unstable cabinet power, wiring short circuit, or a related power module problem, replacing only the PCB may cause repeated failure.

For overseas buyers, sending complete old-board photos is usually the safest way to confirm whether the required item is KCR-1140A, KCR-1141A, KCR-1142A, KCR-1143A, or another Mitsubishi KCR series board.
