2x FK820 VOLTAGE CONVERTER BOOSTER,DC TO DC,12VDC to 15-24VDC 3A, CAR APPLICATION,CIRCUIT BOARD ASSEMBLED KIT (2 Pcs.) Most industrial control and monitoring systems are powered by 24VDC systems. However, battery backing up such systems requires complex battery charging and configuration. On the other hand, 12VDC battery back-up systems are low cost, easily maintained and are readily available. The compact, economical FK820 is an ideal bridge between the two systems and means that 24V systems can be powered from a 12V supply. Furthermore, voltages ranging from 15V, 18V, 19V, 20V, 22V or 24V at 3 Amps may be selected. Applications include industrial controls, monitoring systems and distributed power networks. Technical data - Power supply : 12VDC. more than 10A. - Output voltage : 15V, 18V, 19V, 20V, 22V, 24V (selectable) - Output current : max. 3A. - LED operation indication. - Power supply polarity protected. - IC board dimension : 3.36 in x 2.56 in How does it work When supply voltage to the circuits (shown in Figure 1), TR3 will check the polarity of power supply. If supply, the voltage is inverse polarity, TR3 will not work causing the circuit not working. But supply the voltage is correct polarity, TR3 will work and the circuit will be working. When the circuit is working, IC1 is configured as a voltage booster to boost the voltage level. This voltage booster will feed from the drian of MOSFET to point "OUT" through D1. The voltage level at point "OUT", you can set by the jumper J1 to J4. 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 Connect the components following Figure 2. Supply the power supply to the circuit, LED1 and LED2 are lit on. Remove the jumper J1 to J4 and then measure the voltage at position "OUT". DC voltmeter is showing "15V". Jumping J1, DC voltmeter is showing "18V" and remove J1. Jumping J2, DC voltmeter is showing "20V" and remove J2. Jumping J3, DC voltmeter is showing "22V" and remove J3. Jumping J4, DC voltmeter is showing "24V" and remove J4. In case of DC voltmeter isn't showing other voltage, you can adjust the voltage at VR1. Using - At the position "12V", you have to conecet fuse 15-20A. - At the position "OUT", you have to conecet fuse 3A. - If the circuit is used for a long time. you have to install the DC Fan Example to use: Car Pre-amp need 24Vdc  but battery in car support only 12Vdc, this board can increase voltage to 24Vdc for your application.
