External Dimmer (Potentiometer)

External dimmer to suit Mean Well “AB” and “B” type drivers

This 1-10V potentiometer allows remote dimming of Mean Well “AB” and “B” type drivers, as well as other drivers that use 1-10V external dimmer wires.

This dimmer is not waterproof.

INSTRUCTIONS

* From the driver, connect the positive (+) wire to the positive (+) terminal and the negative (–) wire to the negative (–) terminal – tighten screws.

* Remove black rubber plugs marked Vo (Voltage) and/or Io (Current) and insert a small flat or phillips head screwdriver into the hole.

* Locate internal dial with screwdriver and GENTLY turn clockwise to set maximum voltage and current. Do not force dials!

* If resistance is encountered (hard stop), then dial is set to maximum (clockwise) or minimum (anti-clockwise).

* Once maximum voltage and current are set on the driver, the external dimmer (potentiometer) can now be turned up and down and will not go higher than the master setting – this is how you can safely set the maximum or pre-determined current and/or voltage without exceeding the LED specifications (4.5A on original High Light boards, 5A on High Light 420 boards).

* A common watt/power/wall meter can be used as reference when setting the driver as an alternative to using a multimeter.
