2x FA809 REGULATOR POWER SUPPLY VOLTAGE VARIABLE AC-DC MODULE 0-30V 3A, CIRCUIT BOARD,STUDENT LAB,UN-ASSEMBLED KIT ASSEMBLED KIT (2 Pcs.) Technical information - This regulator circuit is high efficiency because of IC regulator UA723. - It is designed to prevent over power supply maximum to 3A, so it requires transformer 4A with 12-0-12 pole or 24VAC. - PCB dimensions : 3.1” X 2.0” NOTE : This listing has no the the transformer / Switch / Cable / Fuse / Plug cable This is high efficiency regulator circuit by using IC regulator. It is designed to prevent over power supply maximum to 3A, so it requires transformer 4A. with 12-0-12 pole. If lesser than 12V, connecting 12 pole with 0. If more than 12V, connecting 12 pole with 12. Connecting switch according to the figure. Technical data - Need transformer : 12-0-12V 4A. - Voltage output : 0-30VDC (adjustable) - Current maximum : 3A. - IC board dimension : 3.08 in x 1.95 in Circuit performances AC from transformer goes through bridge rectifier diode set which composes of 4 bridge diode changing AC to DC by having C1 as a filter before sending to recgulator circuit. Parallel R value (R1- R5) will be decreased to 2 ohms to detect voltage. If there is over 3A. voltage, voltage at the base is 0.6 volt, making TR3 works. Ther will high voltage at the collector of TR3 and connecting with the base of TR1 making TR1 unworkable, voltage output is down respectively. 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 Connecting transformer from 12, 12 coil to AC and measuring current at "OUT" point. Setting voltmeter at range 50VDC. There would be 0.2-30 volts when adjusting VR1 from minimum to maximum. Application Connecting 12, 0 through switch as per figure 3 shown that requires 0-12 volts. If over 12 volts required, switching to 12, 12 in order to reduce transistor heating OUT is suggested to connect through 3A. Fuse prior to actual usage Free Shipping Handling WORLDWIDE.
