LED Drivers with Analogue Dimming
ADM stocks Australia’s widest range of MEAN WELL LED drivers with analogue dimming.
What is Analogue Dimming?
The term ‘analogue dimming’ is usually used to refer to a LED driver, or other LED lighting control device that is controlled either with a 1-10V, or a 0-10V analogue signal.
Analogue dimming is probably one of the most popular dimming technologies, when it comes to installing LED lighting into new commercial premises and residential homes.
Many modern lighting control systems use a 1-10V, or 0-10V analogue output to control LED lighting.
MEAN WELL LED Drivers with Analogue Dimming
MEAN WELL LED drivers that feature either 3-in-1 dimming, or 2-in-1 dimming are in effect analogue dimmable LED drivers.
Models with 3-in-1 dimming can be controlled with either a 1-10V, or 0-10V analogue signal, depending on the actual model used, as well as a PWM signal, or by applying simple resistance.
If the LED driver has 2-in-1 dimming it can also be controlled with either a 1-10V, or 0-10V analogue signal, depending on the actual model used, and a PWM signal, but there is no option to apply simple resistance.

Our range includes IP67 and IP65 moisture resistant LED drivers, and plastic bodied models for indoor use only. We have both constant voltage and constant current LED drivers in stock with analogue dimming.
Using LED Drivers with Analogue Dimming
Unless you are using a LED driver with a PWM type output you need to be mindful of a phenomenon known as dead travel.
This is where a dimmable LED driver is not being used to its maximum capacity, resulting in an unsatisfactory dimming performance.
For example, if you load a LED driver up to only 50% of its load, nothing happens until the dimmer control has been turned down past 50%, and then the light output suddenly drops.
In the below diagram graph (a) shows even dimming with the LED driver being used to its maximum capacity. Graphs (b) and (c) show what happens to the dimming output if the load on the LED driver is lower that its maximum capacity.
Therefore, ADM recommends that actual load placed on the LED driver is around 90~95% of its maximum output rating to ensure satisfactory dimming.
There are two series of MEAN WELL LED drivers with analogue dimming, that don’t exhibit this phenomenon. They are the IDLV series and the PWM series.
Both have a PWM output, which over comes this problem.
