Summary :
This serial single output switch power supply is a kind of DC regulated power supply.
It has high efficiency, stronger load ability, and long continuous working period characteristics. Also it has perfect over temperature, short-circuit and current limited protections. It cak act as constant voltage as well as constant current DC power supply. This series of power supplies are first choices for scientific and research institutions, colleges, factories units etc.
Before using the power supply:
Do not connect any load to the power supply before it’s turned on. Likewise, make sure to disconnect the load before shutting down the power supply. Damages to the power supply can happen if you do not follow this.
If you are running inductive load like magnetic coils, DC motors, stepper motors, etc., make sure to change the voltage/current slowly, and NEVER turn the power supply on or off with a inductive load connected.
Operating Procedure :
Determine the correct input voltage (110V or 220V, there is a selective switch in the back panel).
Plug in power.
Constant voltage setting :
The coarse and fine current knobs ( CC ) should be clockwise regulated to the maximum. Regulate the coarse and fine voltage regulation knobs ( CV ) to set the necessary voltage, and then connect the load to the “+” and “-“ output terminal. The voltage regulation indicator light will be on, at this moment the power supply is working under the condition of constant voltage. The output voltage remains the same, while the output current changes with the load. When used in places with high demand, make sure one of the output terminal ( + ) or ( - ) must reliably connects with post head ( GND ) so as to reduce output ripple voltage.
Constant current setting :
Clockwise regulate the coarse and fine voltage regulation knobs ( CV ) to set the necessary voltage value, regulate the coarse and fine current knobs ( CC ) to the minimum, and then connect the load to the ( + ) and ( - ) output terminal. Then clockwise regulate the coarse and fine current knobs ( CC ) to the necessary current value, the current regulation indicator light will be on, at this moment the power supply is under the constant current. That is the current remains the same, while the voltage changes with the load.
