Open circuit protection: output no load open circuit, the input is the normal input, the product will not be damaged.

Short circuit protection: If the output abnormal, resulting in positive and negative output short, the product will start short-circuit protection, will not cause permanent harm because of this exception.

Overload protection: This product is current design, the design load range, the output current will be constant, when the output load exceeds the design range, the products into two types of protection status:

v output voltage is too low, the products into frequent startup and shutdown of the protected status, the user will see the LED will be flashing;

v output voltage is too high, the product enters the constant protection of the state, the user can get the test, the LED luminous intensity becomes weak, unable to meet current design value.

v When using the power supply, LED safety please ensure good access to open the power LED.

v power in the power supply approved the use of, pay attention to LED and power supply output current and voltage matching.
