Figure 2: Technical Diagrams for APV-25-12. This image includes a mechanical specification diagram with dimensions (e.g., 84mm length, 57mm width, 29.5mm height) and wire lengths (150±10mm for input, 150±10mm for output, UL1569 18AWG). It also shows a block diagram of the power supply's internal components, a derating curve illustrating output load vs. ambient temperature, and static characteristics showing load vs. input voltage.

Mounting: The unit is designed for surface mount installation. Ensure the mounting location allows for adequate air circulation to dissipate heat.
Input Connection (AC): Connect the AC input wires to your mains power supply. The blue wire is for Neutral (ACN) and the brown wire is for Line (ACL). Ensure connections are secure and insulated.
Output Connection (DC): Connect the DC output wires to your LED lighting or other 12VDC load. The red wire is for positive (V+) and the black wire is for negative (V-). Observe correct polarity to prevent damage to the connected devices.
Load: Ensure the total power consumption of your connected LED load does not exceed 25W.
Environment: Install in a location that is dry and protected from direct moisture, consistent with its IP42 rating.

6. Operating Instructions

Once properly installed and wired, the MEAN WELL APV-25-12 operates automatically. Simply apply AC power to the input terminals, and the unit will provide a stable 12VDC output to the connected load.

Verify all connections are correct and secure before applying power.
Monitor the unit for any unusual heat or noise during initial operation.

7. Maintenance

The APV-25-12 power supply requires minimal maintenance.

Keep the unit clean and free from dust and debris to ensure proper heat dissipation.
Periodically check wiring connections for tightness and signs of wear or damage.
Do not attempt to open or repair the unit. Refer servicing to qualified personnel.

8. Troubleshooting

If the power supply is not functioning as expected, consider the following:

No Output Power:
- Check the AC input power supply.
- Verify all input and output wiring connections are correct and secure.
- Ensure the load does not exceed the power supply's maximum rating (25W).
Intermittent Operation:
- Check for loose connections.
- Ensure the ambient temperature is within the operating range and ventilation is adequate (refer to derating curve in Figure 2).
If issues persist, discontinue use and contact support.
