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

Frequently Asked Questions by Oznium Customers

Placed a 5 amp fuse in my 12 v. led light strip, is that too much ?
A 2-3 amp fuse would be sufficient.
Will this dimmer also work with small incandescent bulbs? I bought it for use with custom car gauges that I thought would have LED's but came with incandescent bulbs. How might it be wired to work with the incandescent bulbs?
Let me check into this further and get back to you.
I want to use a rocker switch from the battery before connecting the dimmer to a LED strip so I can turn it off completely- how should I do this?
Not sure why you would need the rocker switch. The dimmer is an off/on switch also. Best to use that and connect to battery, then wire the dimmer to the strip. If you have more questions please contact Customer Support at 800-245-8131.
Hi how do I connect the red wire to both the power source and the LED?
You can connect 3 wires the same way you'd connect 2 wires. You could simply twist the 3 wires together and cover them with electrical tape or heat-shrink tubing. You could also solder them together. Or you could use a quick splice connector such as these.
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.
