LCD LED LCD TV and monitor switch power supply fully intelligent module instructions
Sub power: 3.3V, 5V dedicated
CA-515 (shared within 36W)
This module is designed for auxiliary power supply maintenance LCD LCD TVs and monitors the damage repair and design, using the maximum power can reach 36W, will let colleagues easily repair LCD vice power, this series of products with small size, easy to install, use the basic realization of full intelligence, high added value, is a major change in the LCD LCD TV power supply maintenance market, welcome to use!
* installation instructions:
(1) first test the +300V DC voltage is normal, then confirm the switch transformer and secondary peripheral components are normal, and then confirm the load without short-circuit fault, and then enter the following operation. .
(2) first remove the MOS or thick film IC on the original machine, then close the module to the heat sink, then fix it on the radiator with a screw lock (the lock screw can not be pressed too tight, otherwise the module will be damaged)
(3) to put in the actual circuit to disconnect the fork, and as shown in modules of each color line to receive good, absolutely can not take the wrong, in the repeated test can't pick up the wrong after boot, honestly! Module lead should not be extended if necessary, otherwise it will affect the normal operation
* wiring instructions:
1, the red line: connected with the main voltage +300V by switching voltage (i.e. Yuan machine MOS tube D, thick film IC D pole).
2, the black line: connected with the cathode, namely power tube Raidi.
3, blue line: the main voltage of the original machine (3.3V or 5V), voltage regulator, optocoupler 4 feet (some of the original machine, multiple optocoupler parallel, according to the original machine method), 3 feet grounding
4, white line: connect the original machine switch, transformer, feedback coil, rectifier diode before (Figure)
5, the green line, connecting the original machine main voltage +300V
