Warning: 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.
Such damages are not under warranty.
Warning: 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!
I 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 voltage, over temperature,
overload protection functions and so on. It can 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 ect.
See the models from the table1.

- Page 5 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. (4)Constant current setting: Firstly, regulate the voltage to any value between 3-10V, and regulate the knob (6) to the minimum.

- Page 7 V Maintenance 1. If the fuse burned out, the power supply will stop working. Please replace it with equivalent fuse. The crisper should not be opened unless something goes wrong. 2. The power supply is precisely regulated before it goes out. Please do not open the power supply unless you are a professional.
