Mini LED Dimmer Knob - Control up to 4.8 amps @ 12V - Customer Questions

Frequently Asked Questions by Oznium Customers

I just tried installing one and it never worked for me. However I did short it, saw a little spark, and blew a 20 amp fuse when it happened. Should work now following the wiring diagram but nothing.
Sorry you are having problems. Please call customer service at 800-245-8131 for assistance.
Does this draw residual current when in the off position?
No. When the knob is turned all the way to the left, it "clicks" off, and zero current is drawn.
Does it work with 12 volts landscaping transformer?
Only if the transformer is 12V DC and not AC.
Does it work with 12 volt AC?
It only works with 12VDC to 24VDC. It doesn't work with AC.
Can this switch be wired in a "high side" fashion?
Sorry, no. It can only switch from the low or negative side.
What is the maximum voltage that your mini LED Dimmer Knob can withstand?

I have a 7S Lithium battery system in my RV. The max voltage (while charging) could be 30V. Will your dimmer work with voltage this high?
Our mini LED Dimmer Knob is designed to work with input voltages between 12VDC to 24VDC.
Sorry, it won't work on 30VDC. We suggest you use a DC-DC step down converter to make sure the voltage is no more than 24V.
