Instructions:
1. Input and output poles are marked in Chinese.
2. Adjustable range of output constant voltage: dc2.5v-58v (turn down clockwise and turn up anticlockwise). Please turn on the load after adjusting the output voltage to the voltage you need when the output is no-load (when the constant voltage power supply, adjust the constant current to 1.2-1.5 times larger than the load current).
3. Adjustable range of output constant current: 0.1a-30a (small clockwise and large anticlockwise). First adjust the output voltage with no load (the load voltage in constant current time and space should be 2-3v higher than the load voltage), adjust the constant current to the minimum, then connect the load and input a ammeter in series at the output, and slowly adjust the current to the current you need.
4. When there is output, the output indicator is on.
Matters Needing Attention:
1. When the input and output voltage is higher than 36V, please pay attention to the safety of power consumption and prevent electric shock.
2. When working with high current, please tighten the screws of the terminal.
3. The input and output voltage and current shall not exceed the maximum value during operation to avoid damaging the power supply.
4. When working at full load for a long time, pay attention to ventilation and heat dissipation to extend the service life of the power supply.
5. Pay attention to dust-proof and moisture-proof.
