How do I adjust the output voltage on a MEAN WELL WDR-60 power supply?

[McAustin]

Adjusting the output voltage of your MEAN WELL WDR-60 power supply allows you to fine-tune it for your specific application requirements. Here's a step-by-step guide:

What You'll Need:

Small flathead screwdriver Multimeter (for accurate voltage measurement)

Voltage Adjustment Procedure:

1. Disconnect the Load: Before making any adjustments, disconnect the power supply from any devices it's powering to prevent potential damage.
2. Locate the Adjustment Potentiometer: On the front of the WDR-60 power supply, you'll find a small potentiometer labeled "V ADJ." This is the voltage adjustment control.
3. Connect the Multimeter: Set your multimeter to measure DC voltage. Connect the multimeter probes to the +V and -V output terminals of the power supply.
4. Power On the Power Supply: Plug in the AC input to the power supply. The typical input range is 100–240 VAC or 180–550 VAC, depending on your WDR-60 model.
5. Adjust the Output Voltage: Using the small flathead screwdriver, insert it into the "V ADJ" potentiometer.
   • Turn clockwise to increase the output voltage.
   • Turn counterclockwise to decrease the output voltage.
   • The adjustment range is typically within ±10% of the rated voltage (e.g., for a 24V model, this usually means an adjustment range from approximately 21.6V to 26.4V).
6. Fine-Tune and Confirm: Continuously monitor the voltage reading on your multimeter as you adjust the potentiometer. Stop adjusting when the desired voltage is achieved.
7. Reconnect the Load: Once you've confirmed that the output voltage is correct and stable, you can safely reconnect your load.

Important Safety Considerations:

Do not exceed the maximum voltage rating of any equipment connected to the power supply. Avoid making adjustments while the power supply is connected to sensitive equipment. Ensure proper ventilation, as these DIN rail power supplies require adequate airflow for optimal performance. Remember to check the label on your specific WDR-60 model (e.g., WDR-60-24, WDR-60-12) to verify its specifications before making any adjustments.
