Triple protection

Short circuit protection


When the load is short-circuited, the product and the load are protected from burning out.

Reverse polarity protection


The product will not be burned out when the positive and negative poles of the power supply are reversed.

Overload protection

 Automatically protect when the load is unstable or the current increases, to avoid product failure.
