See figure 1 for how to hook up a potentiometer to the dimming wires of a Mean Well HLG. This is a variable resistor that easily attaches to the dimming wires for a cost-effective solution. One of the simplest and most affordable solutions to dim with the LED drivers is to use a simple 100k Ohm potentiometer. Potentiometer: Simple resistance dimming with some shortcomings This dimming feature enhances flexibility to make the end-application design much simpler. This ‘3-in-1 dimming’ allows for the user to dim LEDs with three different forms of signal: Passive Resistance, 1-10VDC (0-10V) and Pulse Width Modulation (PWM). Many models like the HLG, NPF and LPF are built with Mean Well’s 3-in-1 dimming feature. Mean Well has developed a wide line of LED drivers with advanced dimming features for LED lighting. Mean Well LED drivers offer dimming features to fit the demand for modern lighting control.
