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 an inductive load like magnetic coils, DC motors, stepper motors, etc., make
sure to connect your load with the output set to zero and change the voltage/current slowly, and NEVER turn the
power supply on or off with a inductive load connected!
4)
Installation: For better heat dissipation, there should be enough space around the power supply. The two sides and
back of the power supply should have 10cm space at least. Some models come with fan controlled by thermistor that
will turn on automatically when the temperature of the heat sink is above 45°C. The power supply comes with
over-temperature protection, and will disable itself when the inside temperature of the device is too high. The power
supply resets itself once the temperature falls below the limit. To ensure proper operation, make sure the ambient
temperature is below 40°C and there is sufficient ventilation.
5) Over-voltage protection: when the OV light is on, the power supply is disabled and in over-voltage protected state,
please follow procedures below (3-3) to reset it.
3-2 Setting Current, Voltage, and OV Limit
There are two ways of setting the output limits, via serial monitor through the USB connection using Arduino software,
