Operation-Adjustable dc power supply1. Before
connecting 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 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. 5. Internal radiating w/*
