The last thing to note is the Mean Well drivers require a current sinking dimmer, not one that provides the 0-10V signal already. The typical dimming response for a 1-10V dimming signal is shown below: A switch setup like described above will help the circuit and keep it turned off when not in use. The output status is not guaranteed when the signal is less than 1V for the Mean Well drivers. 57V or 5.7% light output before cutting off power. 0-10V dimmers on the other hand go down to. For this reason, a switch at the AC main lines is needed to shut off power when the light is not needed. This means the light will only go down to 10%, therefore there will still be some visible light and power going through the system. 1-10V lets the dimming signal go down to 1V or 10% light output. This is where 0-10V and 1-10V dimming drivers are different. When the dimming signal is reduced, the light output will decrease until hitting the minimum output. The same is to be said if you have a dimmer connected and turned up all the way.

When the wires are left untouched (without a dimmer) the signal is at 10V, thus 100% light output. In 0-10V or 1-10V dimmable drivers there is a 10V signal that flows from the Dim (+) line to the Dim (-) line. 1-10V or 0-10V DimmingĠ-10V dimming is a type of dimming where a dimmer is used to alter the control signal of the dimming wires from 1-10VDC to alter the LED brightness. 100K Potentiometers are great for smaller projects where you just need a turn style knob for control, or they are great if you are simply testing the dimming range or output of LED lights. These problems make it so some users might want to look below at electronic potentiometers or 0-10V Dimmers. Second, there is not much of a choice for a frame plate or way to make the potentiometer fully integrate with the aesthetic design of the rest of your application or household. First, the dimming response is very shaky and not very good in the case when there are multiple drivers connected to one potentiometer. There are two main drawbacks to this type of dimming that need to be considered for the end application design.

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.
