1. communication220VPlease install the incoming cable1AFuse 2.Please weld carefully，The polarity of components must not be reversed，Especially large electrolysis！ First power on Stay away from the motherboard！ Prevention of welding errors Electrolysis shooting event！ ！！ Voltage current potentiometer Be sure to weld and weld Firm contact！！！ In use If the potentiometer is disconnected， There will be 30VVoltage and5A Current output ！！！ The circuit element parameters are30V5ADesign，Please don"'"t feel free Increase the output voltage and current！！！ 3.Kit not included： （1）150W-180Wtransformer( electric current5A ） Can be customizedSpecify the required3A voltageOutput value15V 23V 31V ( 5A) Add a double12VTo double15Velectric current1AWinding of Do it on a transformer， use How to dismantle a broken power supply Most suitable。 Or the power amplifier electric current5A Of double12VTo double15V 。Add one15WSmall transformer。 （2）Voltage and current meter（3） 2individualTIP3055Heat sink， （4） 12V 0.2ACooling fan （5）Housing and red blackTerminal Simple circuit description： L1It is the auxiliary control power supply， Center tappeddouble12Vtodouble15 Voltage electric current1A Transformer of thisL1The winding should preferably be connected to the main power supply Around a transformer。Transformer in hand No, Such a winding You can also use oneIndependent small transformer， But we need to talk to himL2 For main transformer The same switch controls on-off 。 L2Main voltage output，More power is needed。150W--180W output30VIn my words，The suitable tap voltage is0V-15V-23V-31V.electric current5A （ be careful After rectification The voltage should be at50Vwithin！best40Vwithin！！！）
