Manual PWM dimmer regulator, with adjustable frequency and regulation curve

For 12/24V monochrome LED strips, max. 30A

Dimmer for 12/24V LED strips that allows you to adjust the frequency and regulation curve. Depending on the selected frequency option from 300Hz to 10KHz, it will allow connecting a larger or smaller load, with a maximum of 30A at the lowest frequency and a maximum of 10A at the highest frequency.

Why is it important to set the frequency correctly?

Although the human eye does not perceive flickers beyond 100 hertz, electronic devices, photo, and video cameras typically record between 25 and 60 frames per second. This is why, often when exposing a light source to a camera, we observe an unpleasant flicker. Adjusting the frequency, as well as the dimming curve, minimizes this effect and allows for a smooth light transition from 0.1% to 100% without jumps, without flicker.

User instructions for adjustable frequency manual PWM dimmer

  1. Select the PWM frequency by adjusting the three pins on the left, marked 1 - 2 - 3
  2. Select the regulation curve by adjusting the two pins on the right, marked 4 - 5
  3. Connect the input and output charging wires according to the instructions V+ / V-, from the power supply and output to the LED strip.
  4. Connect the circuit to the power, and operate the rotary knob. The minimum brightness is set with the knob to the left, and the maximum brightness to the right.
  5. If you turn the knob all the way to the left, you will feel a click and the dimmer will disconnect the power.

Considerations to take into account

  • When the PWM frequency is at the minimum of 300Hz and the maximum load connected is 30A, the temperature of the controller does not exceed 55ºC. When the PWM frequency is between 500Hz and 1000Hz, the controller can reach temperatures of up to 65ºC.
  • Consider that at higher PWM frequency, the output current is reduced proportionally, according to the following table:

PWM freq. = 300Hz --> Max. 30A

PWM freq. = 3KHz --> Max. 20A

PWM freq. = 5KHz --> Max. 15A

PWM freq. = 10KHz --> Max. 10A
