2x FK816 POWER SUPPLY REGULATOR VARIABLE MODULE, AC-DC,0-50V,3A,LM723,2SC5200,ELECTRONIC CIRCUIT, UN-ASSEMBLED KIT (2 Pcs.) This item is UN-Assembled kit which buyer has to put all components on PCB board and do soldering. The FK816, 0-50V power supply is capable of delivering up to 3 Amps into hobby, school, laboratory, repair-shop and telecommunications projects. The voltage can be continuously varied by the on-board spindle pot making it suitable for building into a case. Technical information - This circuit is Regulator Power Supply OUTPUT DC Adjustment 0-50V / 3A Max , 24 - 18 -0 - 18 - 24 AC Input transformer 3-4AMP. Build in overload current protection. - AC input = 48VAC at least 3A - OUTPUT = DC 0-50V, Maximum current at 3A. - PCB size : 7cm( W ) x 11.6cm ( L ) and Hight = 4.6cm. All measurements are already include size of heat sink. (4.53" x 1.82" ) NOTE : ***NOT INCLUDING THE AC-AC TRANSFORMER it is heavy at 1.5kg *** How does it work The AC from the transformer passes diodes D1 to D4 to rectify into DC. C1 has the duty to filter the voltage and transmit through R1 and R2 toward TR5 which is under control of IC1 at the point OUT. By adjusting VR1 the voltage shall vary from 0 to 50 volts. R1 and R2, with helps of TR1 and TR2, will eliminate the excess current and the output voltage at leg E of TR2 by passing LED1 and entering leg 2 of IC1, and the circuit will finally cease supplying power. SW1 will reset the circuit to restart its performances. It is recommended to fix TR5 and the mica plate to the sink before assembling them on the PCB - fix it firmly with nuts and bolts to the sink - and then solder the leg of R5. R1, R2, D1 to D4 shall be mounted a bit above the PCB for heat repelling. PCB assembly Shown in Figure 3 is the assembled PCB. Starting with the lowest height components first, taking care not to short any tracks or touch the edge connector with solder. Some tracks run under components, and care should be taken not to short out these tracks. Testing Connect the rectifier as per Fig. 3. Choose the rectifier's coil corresponding to your requirement by adjusting at point OUT. Measure the output at point OUT with a voltmeter and supply power to the rectifier. Observe the voltmeter. The measured voltage shall be from 0 to 50 volts depending on the adjustment of VR1. Free Shipping Handling WORLDWIDE.
