A potentiometer is a simple component that has established itself as an inexpensive solution for dimming LED drivers. Our potentiometer sits in a practical housing that can be ideally mounted on the 40 mm aluminium profiles. Simply connect to the B- or AB-type driver with WAGO terminals and the dimmer is ready to go!
With a potentiometer you can LED Drivers dimming, the one suitable for it Control input have. These are, for example, all Mean Well drivers, which are marked with -B or -AB at the end of the product name.
The Potentiometer is a variable resistor that can be connected to the signal line of these drivers to act as a dimmer. For a LED driver you need 100 kOhm variable resistor. With a potentiometer, several LED drivers can be dimmed synchronously. However, if several drivers are used, the resistance of the potentiometer should be selected correctly.
Which potentiometer for several drivers
1 driver: 100 kOhm
2 drivers: 50 kOhm
3 drivers: 33 kOhm
4 drivers: 25 kOhm
5 drivers: 20 kOhm
etc... the formula is 100kOhm / n [number of drivers]
Currently 100 kOhm and 50 kOhm potentiometers are available. Other resistance values can be provided on request.
For many drivers, ideally a 0-10 V controller should be used, as it is built into the CresControl. Besides the obvious advantages of the App-Control, this control has no restrictions due to resistance tolerances. When using potentiometers as dimmers for many drivers, small delays between the individual devices may occur.
Excellent unit, works like a charm. It is worth noting that, while I waited for this potentiometer to ship to the U.S., I tried to build my own. I used a proper example (50kOhm for 2x240W drivers, linear taper, etc.), yet I wasn't happy with its choppy performance and unhappier yet with its bare-bones look (no casing).
Once the Crescience unit arrived, I wired it right up. It has wire leads so there is no need for soldering, unlike with my previous experiment. Again, it worked great! By the way, to wire this to a Meanwell B-type driver, you will connect white to white and blue to brown - this isn't noted in the description and no instructions were provided. Once you fire it up and start adjusting the knob, the response is very slightly delayed, maybe by half a second or less. The item description here admits this will happen when multiple drivers are wired to one potentiometer, and I want to emphasize that the delay is de minimis and the transition is extremely smooth, not choppy like my homebrew potentiometer had been.
The casing is well made with a quality matte finish and appears durable. The knob has a very certain, positive feel, it's easy to feel the limits and to make fine adjustments between them.
If I had to nitpick, I would ask Crescience to add markings to clearly show min/max positions and maybe 3-5 position marks in between. Besides that, it's perfect, and in my opinion easily worth more than the €15 asking price.

Hi Dmitry, thank you very much for your positive feedback. Glad your potentiometer finally arrived! By the way, regarding the wiring - it should not matter which way you connect the wires. White to blue and brown to white should work, too! We will consider to put somoe markings on there for future versions 🙂
Which components do I need for my area, how do the modules and drivers affect the spectrum? This calculation work and more is done by our Grow LED Wizard.
