Mitsubishi Power Board KCR-1090A

Mitsubishi Power Board KCR-1090A is a Mitsubishi elevator PCB board used in elevator electrical control cabinet applications.

In the elevator spare parts market, Mitsubishi KCR series boards are commonly described under several names, including power board, drive board, power supply board, and elevator PCB board. Because different KCR boards may serve different functions depending on the elevator system, the exact printed model number on the original PCB should be used as the main confirmation reference.

For this product, the key model is:

• KCR-1090A

At present, public information for KCR-1090A is limited, so it is better to confirm this board by old PCB photos, connector layout, cabinet position, and Mitsubishi elevator system information before ordering.

Related KCR Series References

Customers searching for Mitsubishi KCR series boards may also encounter related KCR model references such as:

• KCR-905B
• KCR-906B
• KCR-907B
• KCR-908B
• KCR-910A
• KCR-910B
• KCR-910C

• KCR-975A
• KCR-976A
• KCR-977A
• KCR-1011C
• KCR-1130A
• KCR-1136A

These should be treated as related KCR series search references, not automatic replacement models for KCR-1090A. Public listings show that different KCR boards are used as drive boards, power boards, or power supply boards in different Mitsubishi elevator systems.

Why Exact PCB Matching Matters

Mitsubishi KCR series boards may look similar from the outside, but the board function, connector layout, PCB revision, and cabinet wiring can be different.

For this reason, KCR-1090A should not be selected only by appearance or by the general name “power board.”

Before ordering, please confirm:

• KCR-1090A marking on the original PCB
• front and back photos of the board
• connector quantity and position
• board size and mounting holes
• elevator control cabinet position
• surrounding wiring condition
• visible fault or damaged area
• original Mitsubishi elevator model if available

If the old board label is unclear, a complete control cabinet photo and close-up PCB photos can help confirm the correct replacement.

Replacement Notes for Maintenance

Technicians usually inspect this type of PCB when the elevator cabinet shows abnormal power response, drive-related board fault, startup abnormality, fuse failure, or visible PCB damage.

Before replacing KCR-1090A, maintenance teams should also check the surrounding cabinet circuit, including:

• power input condition
• fuse or protection circuit
• connector oxidation
• wiring terminals
• related drive or power supply section
• signs of overheating or short circuit

If the original board was damaged by an external wiring problem or unstable cabinet power, replacing only the PCB may cause repeated failure.

Practical Supply Reminder

For overseas buyers, the safest way to confirm Mitsubishi Power Board KCR-1090A is to provide clear photos of the original board.

Because KCR series boards include many different power, drive, and control PCB models, final supply should be based on the exact board label and physical layout, not only the KCR prefix.
