Mitsubishi Capacitor Drive Board KCN-1210A KCN-1211A

Mitsubishi Capacitor Drive Board KCN-1210A KCN-1211A is a Mitsubishi elevator PCB board used in drive cabinet and capacitance circuit applications.

In the elevator spare parts market, this type of board may also be called:

• Mitsubishi Elevator Capacitance Drive Board
• Mitsubishi Elevator Capacitance Board
• Mitsubishi Elevator Capacitor Board
• Mitsubishi Elevator Drive Power Board
• Mitsubishi Elevator PCB Board

For this product, the most important point is the exact marking printed on the original PCB. The KCN series and KCR series can look similar in product names, but they are different board references and should not be mixed during replacement.

Model Confirmation Notes

This page can cover the following search references:

• KCN-1210A
• KCN-1211A
• KCN-1211B
• Mitsubishi Elevator Capacitance Drive Board
• Mitsubishi Elevator Capacitor Drive Board
• Mitsubishi Elevator Capacitance Board

Public supplier listings commonly show KCN-1210A / KCN-1211B as Mitsubishi elevator capacitance drive board or capacitance board models.

If the old board label shows KCN-1211A, please use the actual board label as the final reference. If the old board shows KCN-1211B, do not replace it with KCN-1211A only because the number looks close.

There is also another similar group: KCR-1210A / KCR-1211A, which is usually listed as Mitsubishi elevator drive board or drive PCB, not KCN capacitance board.

What Buyers Should Check First

For this kind of Mitsubishi drive cabinet board, most buyers confirm the part by photo rather than only by elevator model.

Before ordering, please check:

• whether the board marking is KCN or KCR
• complete model number: KCN-1210A / KCN-1211A / KCN-1211B
• connector quantity and position
• capacitor arrangement on the PCB
• board size and mounting holes
• front and back photos of the old board
• elevator drive cabinet installation position

This helps avoid ordering a visually similar board from another Mitsubishi PCB series.

Maintenance and Replacement Notes

Capacitor drive boards are usually related to the elevator drive cabinet power circuit. Technicians may inspect this board when there are drive cabinet faults, abnormal charging behavior, visible capacitor aging, damaged PCB components, or unstable startup conditions.

Before installing a replacement board, the surrounding drive circuit should also be checked. If the old board was damaged by an external short circuit, unstable cabinet power, damaged IGBT module, or charging circuit fault, replacing only the PCB may cause the new board to fail again.

For overseas buyers, clear old-board photos are the fastest way to confirm whether the required model is KCN-1210A, KCN-1211A, KCN-1211B, or another Mitsubishi drive cabinet PCB.

Practical Supply Reminder

Please do not select this board only by appearance.

If the label is unclear, send photos of the whole drive cabinet and close-up markings on the board. This is especially important for KCN / KCR series boards because similar model numbers may refer to different Mitsubishi elevator PCB functions.
