Operating Instructions

1. Precautions before use

AC power input: AC power input shall be within the range of rated voltage ±10% 50/60hz.

Warning: the protective conductor of the power line must be earthed to avoid electric

shock.

Instrument installation: Avoid using this power supply in the environment above 40℃.

Reserve enough space for heat emission holes on the rear panel to dissipate heat.

Notice: To avoid damage to the instrument, do not operate it in the environment

above 40℃.

1. Turn on the power switch to make the product work normally.

2. Pull the voltage and current switch to the "V" position and adjust the knob to the right to

increase the output voltage value.

3. Adjust the knob to the left to decrease the output voltage value.

4. Press the adjustment knob forward to change the fine adjustment and coarse adjustment

status.

5. In the fine adjustment state, it is adjusted in steps of about 3mV, and in the coarse

adjustment state, it is adjusted in steps of about 0.15V.

3. Output current regulation

1. When the current gear switch is switched to 0.5A gear, the host can provide a maximum

output current of 0.6A. When the actual output current exceeds about 0.6A, the power

supply will automatically overrange protection. At this time, the power supply will temporarily

shut down the output for about 2S and A buzzer alarm is performed to prompt the user to

switch gears.

2. When the current gear switch is switched to 5A gear, the host can provide a maximum

current output capacity of about 5.7A. When the output current exceeds the set current

value, the power supply will automatically switch to constant current output.

3. Pull the voltage and current switch to the "I" position. At this time, you can adjust the knob

to change the output current setting value. Pressing the knob forward can also change the

fine adjustment and coarse adjustment status.

Note: When the power supply is in a constant voltage state, the set value of the current

cannot be displayed. In this case, short-circuit the output terminal and the power supply

will enter the constant current state. At this time, the ammeter displays the current set

current value.
