Mitsubishi Power Supply Board A14L-0156-0001#24 ZWS150AF-24/J

Mitsubishi Power Supply Board A14L-0156-0001#24 ZWS150AF-24/J is commonly used in elevator control cabinet and industrial control power supply applications where stable 24V DC output is required.

This power supply unit is usually installed inside the controller cabinet to provide low-voltage power for signal circuits, control boards, relay circuits, communication modules, braking control circuits, or other electronic components.

The unit is commonly identified by both the equipment part number and the power supply model:

• A14L-0156-0001#24
• A14L-0156-0001#24V
• ZWS150AF-24/J
• ZWS150AF-24
• ZWS150AF24
• TDK-Lambda ZWS150AF-24/J
• ZWS150BAF-24

The model ZWS150AF-24/J is listed by TDK-Lambda as an obsolete AC-DC power supply, with ZWS150BAF-24 shown as a recommended alternate part number. However, replacement compatibility should still be confirmed carefully before use.

Model Confirmation Notes

This product is usually ordered by label photo rather than by elevator model.

Before purchase, please confirm:

• original part number: A14L-0156-0001#24
• power supply model: ZWS150AF-24/J
• output voltage: 24V DC
• output current requirement
• connector or terminal layout
• cabinet mounting space
• wiring direction
• whether ZWS150BAF-24 is suitable for the existing cabinet

Some public industrial spare parts listings describe A14L-0156-0001#24 with ZWS150AF-24/J as a 24V 6.3A AC-DC converter with universal AC input. Other catalog information for ZWS150AF24 lists 24V output with 6.3A rated current and 7.5A peak current.

When Buyers Usually Replace This Part

Maintenance teams usually check this power supply when the 24V cabinet circuit becomes unstable.

Typical symptoms may include:

• relay circuit instability
• communication board reset
• controller input error
• abnormal signal response
• intermittent low-voltage faults
• safety or control circuit power interruption

These symptoms can sometimes look like PCB failure. In real maintenance work, technicians usually measure the 24V output under load before replacing expensive control boards.

Replacement Matching Reminder

Do not replace only by appearance.

ZWS150AF series power supplies may look similar, but different voltage versions such as 12V, 15V, 24V, 36V, and 48V are not interchangeable. The /J suffix and cabinet connection structure should also be checked carefully.

If the original ZWS150AF-24/J is no longer available, ZWS150BAF-24 may be considered as a replacement reference, but final selection should depend on electrical output, mounting structure, connector type, and field wiring condition.

For old elevator control cabinets, the fastest confirmation method is to provide a clear photo of the original label and terminal wiring.
