2x FK807 AC-DC REGULATOR 0-12VDC 1A,POWER SUPPLY 12-15 VDC,ELECTRONIC CIRCUIT UN-ASSEMBLED KIT (2Pcs.) This item is un-assembled kit, buyer must assembled and solder all parts by self!! Technical information - This circuit is DC to DC Regulator Power Supply. - This board need 12-15VDC to input and output of board will be 0-12VDC. - Adjustment by potentiometer pot on board.his is fit for the application which need voltage between 0-12V. - For example : 6.5VDC. ( Adjustment is needed to get 6.5VDC ). - Maximum load : 1A. (with 1.5A. transformer) - IC board dimension : 1.28 in x 1.22 in It is a sort of regulating circuit for 0-12VDC appliances. Althrough it is not expensive and works simply but it is worth for use, especially in case it is added to the existing source of power supply e.g. battery or transformer because the voltage can be adjusted throughout the input range of the circuit. If we supply 12VAC to the transformer the output voltage can be continuously adjusted lower by a potentiometer/spindle pot. How does it work Supply 12VDC to the right side of circuit input at leg C of TR1 and in the meantime R1 and VR1 share the voltage from it whereas C2 acts as filter to smoothen the current. Once VR1 is turned the voltage will vary continuously from 0 to 10 volts. The voltage at this point cannot be utilized because it supplies very low current. So we have to connect it to TR2 and TR1 to increase it up to 1A. TR1 shall be of high-voltage durable type. However, a heat repellant fin shall be attached to it at use. The adjusted voltage and the increased current will depart from leg E of TR1. Circuit Assembly 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 Test by supplying 12-16VDC to the circuit input. And measure the voltage with a voltmeter. Adjust VR1 and observe the voltmeter. The reading shall be greater than 0 volt up to a value near to the supplied voltage. Free Shipping Handling WORLDWIDE.
