The PWM-120 LED driver offers dimming functionality to adjust the brightness of the connected LED lights. Here are the dimming options available with this driver and how you can dim the LED lights:
1. **3 in 1 Dimming (Dim-to-Off):** This dimming function allows you to apply one of the three methodologies between DIM+ and DIM-: 0 ~ 10VDC, or 10V PWM signal, or resistance. The dimming source current from the power supply is typically 100μA. You can achieve dimming by adjusting the input voltage, PWM signal, or resistance within the specified ranges.
2. **DALI Interface (for DA/DA2-Type):** For the DA/DA2-Type models, you can apply a DALI signal between DA+ and DA-. The DALI protocol comprises 16 groups and 64 addresses, allowing for precise control over the dimming levels. The first step is fixed at 0.2% of the output, providing a starting point for dimming adjustments.
3. **Dimming Range:** The dimming range of the PWM-120 LED driver is from 0 to 100%, allowing you to adjust the brightness of the LED lights as needed.
To dim the LED lights connected to the PWM-120 LED driver, follow these steps based on the dimming option you are using. Ensure that you refer to the product manual for detailed instructions and compatibility with your specific LED lighting setup.
