How do I adjust the output current on my MEAN WELL ELGT-150-C series LED driver using dimming?

[Vera]

Adjusting the output current of your MEAN WELL ELGT-150-C series LED driver involves using its 3-in-1 dimming function. Here's a breakdown based on the driver type:

For B/AB-Type Drivers:

• Dimming is controlled via DIM+ and DIM- terminals.
• You can adjust the output current using:
  • 0-10VDC signal.
  • 10V PWM signal.
  • Resistance.

For DA-Type Drivers:

• Use a DALI signal between DA+ and DA- terminals.

For D2-Type Drivers:

• Use PROG+ to increase the current level and PROG- to decrease it.

Important Considerations:

• Direct Connection: Connect your LEDs directly to the driver.
• Minimum Dimming: The minimum dimming level is approximately 8%. The output current isn't precisely defined between 0% and 8%.
• Output Current Range: The output current can decrease to 0% when the dimming input is around 0kΩ or 0VDC, or with a 0% duty cycle 10V PWM signal.
• DALI (DA-Type): If using a DA-Type driver, the DALI protocol supports 16 groups and 64 addresses. Consult the MEAN WELL ELGT-150-C series documentation for detailed specifications and how to implement each dimming method for your specific model.
