To adjust the output of the HLG-150H LED driver using the dimming function, follow these steps:
1. **Dimming Methodologies:** The HLG-150H LED driver offers a 3 in 1 dimming function for B/AB-Type models. The output constant current level can be adjusted by applying one of the three methodologies between DIM+ and DIM-:
- **1 ~ 10VDC:** Apply a voltage signal between 1 to 10 volts DC to adjust the output current.
- **10V PWM Signal:** Apply a 10V PWM signal with a frequency range between 100Hz to 3KHz to control the output current.
- **Resistance:** Apply resistance to adjust the output current.
2. **Direct Connection:** It is recommended to directly connect the LEDs to the driver when using the dimming function. Additional drivers are not suitable for use with this dimming feature.
3. **Dimming Source Current:** The dimming source current from the power supply is typically 100μA.
4. **Additional Information:** If you need to turn the lighting fixture down to 0% brightness, refer to the configuration provided in the manual or contact MEAN WELL for other options.
By following these steps and utilizing the dimming function options available on the HLG-150H LED driver, you can effectively adjust the output current to control the brightness of your LED lighting system.
