At the same time, the built-in chip is made of TI chips imported from the United States, and a self reset fuse is added to the circuit design. It automatically disconnects when there is a short circuit outside the power supply or wiring, and can be used normally after being powered on again The copper material terminal post is used, which can be verified by inserting the stamped terminal into the end of the PCB board The power supply is the core of the power switch, using a 155J/630V ultra large CBB capacitor The live wire inlet and outlet are connected by a thick copper wire bridge, abandoning the traditional tin connection to ensure maximum current flow, making it less prone to oxidation and overload. However, on the market, tin is generally added, which is uneven and prone to burnout.
