IV. REFERENCE PICTURE
Operation-Adjustable dc power supply
1. Before connecting with loads, please preset the needed output voltage, check whether the output voltage is suitable or not, or adjust the voltage potentiometer and current potentiometer to a minimum.
2. Please connect with loads when POWER OFF. Then turn Power ON. Turn the Voltage potentiometer, a current potentiometer to a minimum at first. After the power supply machine works steadily, then adjust the needed output voltage which can avoid the overshoot voltage to damage the load's equipment.
3. In running status, you can adjust the voltage potentiometer, a 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.
