Feature: 1. [Reverse Connection Protection] With reverse connection protection pole tube, the reverse connection will not cause the product to burn out. The maximum output current can attain 8A. Wind cooling is required, and it is recommended to be within 5A for long term work. 2. [Voltage Adjustment] The voltage adjustment potentiometer is in the factory setting state, and the knob is adjusted to the maximum value. When using it, it needs to be turned counterclockwise for more than 5 times before the output value will change. 3. [Double Layer Circuit Board] 1.6mm double layer high density fiberglass circuit board, not only thick, long term use will not cause edge delamination and bulging lines, it is a rare and versatile DC Regulator board. 4. [Current Limiting Function] The inductance coil acts on the AC current limiting function. It can form a high pass or low pass filter, a phase shift circuit and a resonant circuit with a resistor or capacitor to pass DC and block AC. 5. [Heat Sink] The aluminum alloy heat sink, with its own heat sink, can meet normal use. It is recommended that the current should not exceed 5A for long term use. If it exceeds 5A, use a fan to dissipate heat.
