Pin Definition:
1-Pin Yellow Wire:DRAIN,power control port.connect with MOS power tube D pole (usually is power switch tube middle pin)
2-Pin Black Or Pink Wire:GND,module ground wire 300V.connect with capacitor negative
5-Pin Green Wire:start pin,connect with 300V capacitor positive
Using Method:
1.Remove original power chip (usually 8-pin) and switch tube (mos tube)
2.Check 300V capacitor
3.Check if load port is short circuit,ad board,inverter board etc
4.Connect module corresponding circuit and check if there is false connection
5.Install it in origial heat sink position,pay attention to insulation,no short circuit
6.Power on,test whether voltage is output or not.please check out the reason if there is no output
Please
Notes:
1. Before using this module, please first check the cold side there is no short circuit, a short circuit of the first maintenance, if the capacitor drum package, please replace the first, high-voltage package circuit is also the first short circuit, not on the module before , Remove the original module power chip and mos tube, this time the original switch tube in the middle of the electrode to the hot ground voltage to have about 300v voltage.
2. Optocoupler 3 feet if not connected to the ground, please put 3 feet heat, while the 4 fe
