Mitsubishi Capacitor Board KCN-930A

Mitsubishi Capacitor Board KCN-930A is a PCB board used in Mitsubishi elevator drive cabinet and capacitance circuit applications.

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

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

KCN-930A is normally confirmed by the printed model number on the original PCB. Because KCN series boards may look similar from the front, replacement should not be selected only by appearance.

KCN Series Model References

This page can naturally cover the following related KCN capacitor board models:

• KCN-910A
• KCN-920A
• KCN-921A
• KCN-930A
• KCN-940A
• KCN-941A
• KCN-942A
• KCN-943A

Public supplier listings commonly group these models together as Mitsubishi elevator capacitor board or MAXIEZ elevator capacitor board references. Other pages also include larger KCN series models such as KCN-1000A, KCN-1010A, KCN-1100A, KCN-1110A, and KCN-1101A in the same elevator capacitance board category.

These numbers are useful for search coverage and quotation matching, but they should not be treated as automatically interchangeable. The final replacement should depend on the original board label, capacitor layout, connector position, and elevator drive cabinet configuration.

Where This Board Is Usually Checked

KCN-930A is usually related to the drive cabinet power or capacitance section.

Technicians may inspect this board when there are signs such as:

• drive cabinet fault indication
• abnormal charging behavior
• visible capacitor aging
• unstable drive startup
• damaged PCB components
• suspected capacitance board failure
• overheating marks around the board

These symptoms may also come from the surrounding drive circuit, power module, wiring terminals, fuse protection, or cabinet power condition. For this reason, the complete drive cabinet should be checked before replacing the board.

What Buyers Should Confirm

For accurate supply, please provide:

• clear photo of the KCN-930A marking
• front and back photos of the PCB
• connector quantity and direction
• capacitor arrangement on the board
• installation position inside the drive cabinet
• nearby board numbers if visible
• fault description from the maintenance technician

If the old label is unclear, photos of the complete drive cabinet and close-up PCB markings can help confirm whether the required board is KCN-930A or another KCN series capacitor board.

Practical Replacement Note

KCN-930A should be handled as part of the elevator drive power circuit, not as a simple low-voltage signal board.

Before installation, technicians usually check the surrounding power circuit, capacitor condition, fuse or protection circuit, wiring terminals, and signs of overheating. If the old board was damaged by external circuit problems, replacing only the PCB may cause repeated failure.

For overseas buyers, matching the exact KCN model first and checking the physical layout second is the safest way to avoid wrong supply.
