JP-02 amplifier power supply has been well recognized by music lovers all over the world. Each of its circuits has independent short-circuit protection and independent short-circuit protection indicator. Even if any one of the roads is short-circuited, other branches can work normally. With a user-friendly LED control switch design, the LED array illuminates all effects on the board. 7-channel 9V100mA output, 1 channel 9V500mA output and 12V, 18V output each, to meet the power supply requirements of any different effects. The chip has perfect protection circuit, including current limit and thermal shutdown circuit. The peripheral components form a high-efficiency voltage regulator circuit. Features low-noise, high-performance and peripheral-simplified switching, the power adapter fully meets the six-level energy efficiency standard, meets national certification standards, and provides extremely comprehensive safety certification and excellent performance protection functions, including overcurrent protection overload protection and overheat protection, etc. With a whole patent layout, it is safe and secure, simple and cool, easy to carry the effect of the power supply, which let you enjoy unimpeded music.
