Warning: Do not connect any load to the power supply before it's turned on. Likewise, make sure to disconnect the load before shutting down the power supply. Damages to the power supply can happen if you do not follow this. Such damages are not under warranty.

(1) Digital ammeter: display the output current value (2) Over voltage protection setting knob: regulate the value of the over voltage protection. (3) Current regulation setting knob: regulate the current value of the current regulation. (4) Current regulation indicator light: When the power supply is under the current regulation, the indicator light is on.

4. Constant current setting: Firstly, regulate the voltage to any value between 3-10V, and regulate the knob (3) to the minimum. (0A), and then use a lead to make positive and negative polarities shorted. Regulate the Current regulation setting knob (3) to the necessary current value. Remove the short lead, and then regulate the voltage to the necessary value, connect the load, then you can start your work.

2. Working condition: For the purpose of heat dissipation, there should be enough space around the power supply. The two sides and back of the power supply should have more than 10cm space. This kind of power supply uses intelligent fan controlled by temperature to cool. When inside temperature of the power supply is no less than 45 C, the fan start to work, while the temperature is less than 45...

12V, counterclockwise regulate the over voltage protection setting knob (2) until the indicator light (5) is on. At this moment, the power supply has no voltage output. Regulate the voltage less than 12V (setting value), turn off the power supply. The indicator light will be off after about 10 seconds. Restart the power supply, regulate the voltage to the necessary value, then you can start your work.

Pay attention: as the rated power is high, it should use Air-switch but not plug in order to keep the power supply from damage. On the cable of the power supply, there have used sticks to show which one is live wire, which wire is nature wire and the ground wire.
