Using a Meanwell Dimmable Driver (Skip if not using a Meanwell
Dimmable Driver)
Wiring the Driver Dimmer Wires
There are 4 output wires on a dimmable driver as in the above photo. The dimming wires, DIM
+ (blue), and DIM – (white), simply hook up to the respective ports on your controller or dimmer.
Dimmable drivers must have the dimmer wires hooked up to a controller or dimmer or the LEDs will not
light up. No dimming signal = 0% brightness.
If you do not have a dimming circuit or controller, you can test by applying a voltage to the
and Dimmer – wires on the driver. This voltage can range from 1-10V. Do NOT exceed 10V or
you risk damaging the dimming circuitry. A 1V reference voltage will light the LEDs to 10% brightness,
whereas a 10V reference voltage will light the LEDs to 100% brightness. You likely have something
around your house that can supply a reference voltage. A “wall wart,” 9V battery, or even a AA battery
can be used for testing. Be sure to test the actual output voltage of your wall wart with a multimeter
before use – unregulated wall warts will output much greater than the output voltage on the label when
used with small loads.
Adjusting Driver Current – Do this before applying power if needed
To adjust the driver output current, open the driver by removing the 4 screws and very gently
rotate SVR2 counter-clockwise until it stops. Counter-clockwise rotation lowers output current and
clockwise rotation raises output current. We have just set current to the minimum. Adjust maximum
driver current such that it does not exceed the specification of your LEDs!
