5V : 4.8V~5.15V 12V : 11.8V~12.4V3.3V : 3.2V~3.4V

Output voltage can be adjusted within the safety range to meet special applications.Output voltage must be adjusted by a tiny screw driver enclosed in the package. To adjust the output voltage, insert the enclosed screw driver to the selected voltage hole and turn right to increase the voltage and left to decrease the voltage.

3.Pre-cautions: Cautions! Unauthorized Personal should not do the following in order to avoid electrical shock! 3.1 Do not open the top cover of power supply case! 3.2 Before turning on the power supply, please make sure if the input voltage of the slide switch set on power supply corresponds to the power voltage given in your environment (US, Canada: 115V. Europe, Central America, South America: 230V ). 3.3 Please keep the power supply from humidity.

4.Safety: Our power supply has been certified to comply with multi-national Safety.

2.6 Protection: The power supply itself is designed with both over load and short circuit protection functions described as bellow: When the total load exceeds 130% to 160% of the max. Output current, the power supply shall be latch into the state of shutdown. When any set of DC output is in short circuit, power supply shall be latch into the state of shutdown in order to protect the circuit from being damaged.
