Depending on the selected frequency option from 300Hz to 10KHz, it will allow to connect a higher or lower load, with a maximum of 30A at the lowest frequency, and a maximum of 10A at the highest frequency.\u003c\/p\u003e \u003ch3\u003eWhy is it important to set the frequency correctly?\u003c\/h3\u003e \u003cp\u003eAlthough the human eye does not perceive flicker beyond 100 Hertz, electronic devices, photo and video cameras usually record between 25 and 60 frames per second. That is why, many times, when exposing a point of light to a camera, we observe an unpleasant flicker. The frequency setting as well as the dimming curve reduces this effect to a minimum and allows dimming with a homogeneous light transition from 0.1% to 100% without jumps, without flicker.\u003c\/p\u003e \u003ch3\u003eTechnical parameters\u003c\/h3\u003e \u003cul\u003e\u003cli\u003eOperating temperature: -20ºC to 60ºC\u003c\/li\u003e \u003cli\u003eInput \/ output voltage: 12\/24V\u003c\/li\u003e \u003cli\u003eOutput: 1 channel\u003c\/li\u003e \u003cli\u003eWiring connection via terminal strip\u003c\/li\u003e \u003cli\u003eSmall dimensions: 90x70x48mm\u003c\/li\u003e \u003cli\u003eWeight: 140g\u003c\/li\u003e \u003cli\u003eStatic power consumption: \u003c0.7W\u003c\/li\u003e \u003cli\u003eOutput current: \u003c30A\u003c\/li\u003e \u003c\/ul\u003e\u003ch3\u003eInstructions for using the adjustable frequency manual PWM regulator\u003c\/h3\u003e \u003col\u003e\u003cli\u003eSelect the PWM frequency by adjusting the three pins on the left, marked 1 - 2 - 3\u003c\/li\u003e \u003cli\u003eSelect the regulation curve by adjusting the two pins on the right, marked 4 - 5\u003c\/li\u003e \u003cli\u003eConnect the input and output load wires according to the V+ \/ V- instructions, from the power supply and output to the LED strip.\u003c\/li\u003e \u003cli\u003eConnect the circuit to power, and operate the rotary knob.
