tried dimmer

Reviewed the specifications of the dimmer units:
  • working temperature: -20 to 60°C
  • input supply voltage: 12 to 24 VDC
  • maximum load current: 8 amperes
Tested one of the four dimmer units. First with a super bright red LED and then with the 2-inch Kendrick dew heater wrap.

With the knob at OFF, it output 0 volts and 0 amps.

With the knob turned slightly, it output 12+ volts and low amps.

With the knob at maximum (over 270°), the amperage read as 0.27.

One will need to be careful with the polarity. Particularly the input...

Immediately I started to think of applications:
  • dedicated heater for finder scope
  • dedicated heater for camera lens
  • tripod lighting
Lots of ideas... And immediately I wondered what new parts I'll need. Do I have female RCA plugs for example?
