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 for 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.
