Add to Wishlist


2 Channel PWM (pulse wave modulation) dimmers are ideal for controlling more than one bank of LED or incandescent lighting, such as 2-color LED light strips or any combination of lighting (panel lighting, overhead map lights, foot well lighting, etc.). Each rheostat controls a separate lighting channel and contains its own On/Off switch (in the fully counterclockwise position)

1.5 Amp per channel version (12-14VDC systems) controls up to 18W per channel
7 Amp per channel version (12-14VDC systems) control up to 97W per channel and adds over-current protection and dual independent heat sinks
Ideal for LED or incandescent lighting
Dual rheostat shafts permit independent control of each channel
Screw-down terminals for easy connection of input and output wires
Powerful enough to operate a wide range of lighting products
High-quality push-on knob. Shaft length accommodates panel widths to 5mm

I see a lot of reports of failure here. I originally purchased one of these in 2015 to drive two LED strips for panel and flood lights in my RV-8. It worked flawlessly for several hundred flight hours (probably 10-20 hours actual lighting) and 5 elapsed years. I recently purchased a replacement after I physically damaged the original during a panel upgrade. The new one has added heat sinks on the transistors which should help. Here is my issue. The new replacement has slightly wider placement of the two POTs, requiring me to remake a panel overlay. I may return the product and make my own PWM which is a very simple circuit.

Right out of the box, one channel sputters and blinks in the lower 30% or so of its range. I swapped my red and white LED segments and confirmed that its the drivers and not the load causing this. Disappointed and wouldnt buy again.

Installed dual channel unit to control strip lighting. Worked great for 5 hours, then one channel lost its low end range. Doesnt come on until too bright to be useable at night.

This unit was defective right out of the box. I hooked it up, and it will control 2 channels of LED strip lights. When I mounted it in the panel, the unit grounds out and both channels go out. Unusable.

Q: What is the warranty on this item?

Per the supplier: The Dual Channel PWM Dimmer has a 30 day warranty from customer receipt of product.

Q: I would want to know the panel cutout dimensions for the two-chanel PWM dimmer with part number 11-10783. Could you provide me this information?

We have updated the full instructions and specifications to the "Documents" tab of this page including the mechanical drawing of the unit with the full dimensions.

Q: The instructions say to Always place a properly rated fuse between the dimmer and power source. What size fuse or breaker is needed?

The fuse or breaker size is determined by the load. For most installations it would be quite small - 1 amp or 2 amps.
