DC Motor Speed Control HHO PWM electronic circuit PCB board kit DIY 12-50VDC 5A 50Hz UN-ASSEMBLED KIT This is a speed control circuit for a DC motor. Not only the speed of the motor can be controlled but the frequency also adjustable.(due to the application of Plus Width Modulation technique) Technical data - Power supply : 12-50VDC. (jumper selection). - Load voltage : 12-50VDC./ 5A. max. - Motor speed (PWM) can be adjusted from 0% to 100%. - Can be adjusted frequency 3 ranges (jumper selection). 1. Frequency range from 50Hz - 1kHz. 2. Frequency range from 240Hz - 13.84kHz. 3.Frequency range from 1.9kHz - 100kHz. - IC board dimension : 3.01 in x 1.83 in. How does it work IC1 generates the frequency with respect to the values of R1, R2, VR1 and C3 whereas VR1 adjusts the frequency as desired. If the positive pulse is greater than the negative one, then the motor revolves quickly. But if the negative pulse is greater than the positive one, then the motor revolves slower. The frequency will be sent through the base of TR1 and TR2 for driving the mosfet for control the motor. Jumper JF1 and JF2 are used for select the frequency and jumper J1-J4 are used for select the voltage of power supply and motor. Circuit Assembling The assembly of components is shown in Fig. 2. For good looking and easy assembly, the shorter components should be first installed - starting with low resistant components and then the higher. An important thing is that diodes, electrolyte capacitors, and transistors shall be carefully assembled before mounting them onto their right anode/cathode of the IC board otherwise it might cause damage to the components or the circuit. Configuration of the anode and the cathode is shown in Fig 3. Use the soldering iron/gun not exceeding 40 watts and the solder of tin-lead 60:40 with flux within. Recheck the correctness of installation after soldering. In case of wrong position, just use lead absorber or lead extractor wire to avoid probable damage to the IC. Testing Connect a motor at point M+ and M- to energize the circuit - the anode to M+ pole and the cathode to M- pole. For power supply, select the jumper J1-J4 to match the voltage applied to the motor. The voltage can be selected 4 ranges : J1 for 12V, J2 for 24V, J3 for 30V and J4 for 50V. Select the frequency range is 3 ranges (JF1 and JF2) : jumping JF2 only, 50Hz-1kHz. Jumping JF1 only, 240Hz- 13.84kHz and not jumping JF1 and JF2, 1.9kHz-100kHz. VR1 is used for the adjustment of frequency while VR2 is used for the adjustment of speed. NOTE: - Frequency recommended for general use is 50-200Hz. - If the connecting load is more than 1A and working continuously, a mini fan should be installed at the heatsink. Warning : Before use to choose jumper J1-J4 to match the voltage supply to the circuit. Free Shipping Handling WORLDWIDE.
