Several public spare parts listings describe this product as Z59LX-42 / Z59LX-46 / P203031C180G01 / P203031C180G02. One listing shows Z59LX-42 with part numbers P203031C180G01 / P203031C180G02, while another identifies CTQ1000AMIT Z59LX-46 P203031C180G01 and CTQ1000BMIT Z59LX-42 P203031C180G01 as Mitsubishi LEHY-3 switching power supply references.

These model numbers should be treated as related power supply references. Before ordering, the original label, CTQ marking, part number, connector structure, and cabinet wiring should be confirmed carefully.

How Buyers Usually Confirm This Power Supply

Most inquiries for Z59LX-42 or Z59LX-46 come with a photo of the old power supply box.

Before purchase, please confirm:

• Z59LX-42 or Z59LX-46 marking
• CTQ1000AMIT or CTQ1000BMIT label
• P203031C180G01 / P203031C180G02 part number
• connector position
• cabinet wiring direction
• elevator control cabinet model
• front and side photos of the original unit

This is especially important because Z59LX-42 and Z59LX-46 may appear together in listings, but they should not be treated as automatically interchangeable without checking the original cabinet configuration.

When This Power Supply Is Usually Checked

Maintenance teams usually inspect this power supply box when the elevator cabinet shows unstable electronic behavior, such as:

• display reset
• communication board restart
• controller input abnormality
• signal circuit instability
• random low-voltage faults
• abnormal cabinet power response

These problems may look like PCB failure. In real maintenance work, technicians often check the power supply box and cabinet terminals before replacing expensive controller boards.

Replacement Matching Reminder

For Mitsubishi Lingyun-3 / LEHY-3 related elevator systems, matching the old model label is more reliable than selecting by appearance only.

Before installing a replacement unit, technicians usually check:

• input power condition
• output condition
• connector locking
• fuse or protection circuit
• cabinet grounding
• terminal oxidation

If the old power supply failed because of external wiring problems or cabinet power instability, replacing only the power supply box may not fully solve the issue.
