 Operation-variable dc power supply

1. Before connect with loads, please preset the needed output voltage, or check the output voltage is suitable or not, or adjust the voltage potentiometer and current potentiometer to minimum.
2. Please connect with loads when POWER OFF. Then turn Power ON. Turn the Voltage potentiometer, current potentiometer to minimum at first. After power supply machine works steadily, then adjust the needed output voltage which can avoid the overshoot voltage to damage the loads equipments.
3. In running status, you can adjust the voltage potentiometer, current potentiometer to change the output voltage and output current as you need.
4. Internal fan is temperature-control, only when high temperature, the fan will work, when low temperature the fan will stop.
5. Internal radiating wind hole: left-in and right-out, please make sure there is no barrier in the left and right wind hole.
