Mitsubishi Capacitor Board KCN-1101A

Mitsubishi Capacitor Board KCN-1101A is commonly used in Mitsubishi elevator control cabinet and drive power circuit systems.

This board is usually related to the elevator inverter, charging circuit, capacitor circuit, or high-voltage power supply section inside the control cabinet. In the elevator spare parts market, this type of board may also be called:

• capacitor board
• capacitance board
• charger board
• drive power board
• control cabinet high-voltage power board

For this product, the exact KCN model number printed on the PCB is more important than the general product name. Similar KCN boards may look close from the outside but belong to different drive cabinet configurations.

Related KCN Series Models

This Mitsubishi capacitor board may be searched under several related model numbers:

• KCN-1100A
• KCN-1101A
• KCN-1110A
• KCN-1210A
• KCN-1211B
• KCN-1000A
• KCN-1010

Some market listings show KCN-1101A, KCN-1110A, and KCN-1100A together as Mitsubishi elevator capacitor board / capacitor panel references. Other elevator spare parts pages list KCN-1110A, KCN-1000A, and KCN-1010 together as Mitsubishi elevator power supply board / capacitor board models.

These models should be treated as related KCN series references, not automatically interchangeable replacements.

How Buyers Usually Confirm This Board

Most inquiries for KCN-1101A come with a photo of the old board rather than only an elevator model.

Before purchase, it is better to confirm:

• KCN-1101A marking on the PCB
• complete cabinet photo
• connector quantity and position
• capacitor layout
• board size
• Mitsubishi elevator model or control cabinet type
• whether the original board is KCN-1100A / KCN-1101A / KCN-1110A / KCN-1210A series

Because KCN series boards are often installed in the drive or high-voltage section, technicians usually check the surrounding circuit before installing a replacement board.

Replacement Reminder for Drive Cabinets

A capacitor board is rarely judged only by appearance.

In real maintenance work, technicians may inspect this board when the elevator has:

• inverter cabinet fault indication
• abnormal charging behavior
• visible capacitor aging
• unstable drive startup
• high-voltage circuit abnormality
• damaged PCB components
• suspected charger board failure

For older elevators, Mitsubishi maintenance guidance also notes that circuit boards equipped with electrolytic capacitors may require attention because capacitor aging can occur over long-term operation.

Practical Notes Before Installation

Before replacing KCN-1101A, technicians usually inspect:

• cabinet input condition
• capacitor condition
• wiring terminals
• charging circuit
• inverter section
• related fuse or protection circuit
• signs of overheating or component damage

If the old board was damaged by an external circuit problem, replacing only the capacitor board may cause the new board to fail again. A front and back photo of the PCB is usually the fastest way to confirm the correct replacement.
