100v 300a variable dc power supply adjustable

1. Preset the output voltage as needed when the output end is not loaded or check if the voltage is proper when it is powered on or preset the potentiometer for voltage adjustment to the minimum. For the safety, potentiometer for voltage adjustment should be adjusted to the minimum in advance.

2. After checking the output voltage, connect loading equipment when the powers supply switch is switched off and then connect the power supply switch.

3. Two potentiometers can be adjusted on the front panel at any time during the operation period so as to change the output constant voltage and output constant current value.
