To adjust the output current level of the MEAN WELL ELGT-150-C series LED driver using the dimming function, you can follow these steps:
1. Dimming Operation: The dimming operation for this LED driver varies based on the type of driver you have. Here are the dimming methods for different types:
- B/AB-Type: Use DIM+ to increase the current level and DIM- to decrease it.
- DA-Type: Apply a DALI signal between DA+ and DA-.
- D2-Type: Use PROG+ to increase the current level and PROG- to decrease it.
2. 3 in 1 Dimming Function (for B/AB-Type): The output constant current level can be adjusted by applying one of the three methodologies between DIM+ and DIM-:
- 0-10VDC
- 10V PWM signal
- Resistance
3. Direct Connection: It is recommended to directly connect the LEDs to the driver without using additional drivers.
4. Min. Dimming Level: The minimum dimming level is about 8%, and the output current is not defined when it is between 0% and 8%.
5. Output Current Adjustment: The output current could drop down to 0% when the dimming input is about 0kΩ or 0VDC, or when using a 10V PWM signal with a 0% duty cycle.
6. XDALI Interface (for DA-Type): If you have a DA-Type driver, apply a DALI signal between DA+ and DA-. The DALI protocol comprises 16 groups and 64 addresses.
By following these steps and utilizing the dimming functions provided by the , you can easily adjust the output current level to suit your specific lighting requirements.
