selector switch as shown in picture below:
Warning
: Changing the AC voltage selector setting must be done with the power supply unplugged from AC.
Warning
: To avoid electrical shock, the grounding conductor of the power cord must be connected to AC ground.
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. Shutting down improperly can cause the power supply to fail when
it’s turned on next time. Damages due to improper startup and/or shutdown are not under warranty.
Warning:
When running an inductive load like magnetic coils, DC motors, stepper motors, etc., make sure to set
the output to zero before connecting the load, change the voltage/current slowly, and NEVER turn the power supply
on or off with a inductive load connected!

Installation: For better heat dissipation, the two sides and back of the power supply should have at least 10cm space
from the walls. The cooling fan is controlled by thermistor and will turn on automatically when the temperature of the
heat sink is above 45°C. The power supply comes with over-temperature (OT) 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
40°C. To ensure proper operation, make sure the ambient temperature is below 40°C and there is sufficient ventilation.
