JSW (three phase) series is the precisely purifying AC power supply. It adopts the most sophisticated power supply adjustment technique of the sine power distribution program with the high efficient broadband filtering network. The main circuit consists of the sine energy distributor mechanism and high-power filter in parallel. When the input voltage or the current of loads changes, the sine power distributor charges power to the induction coil and adjust the inductance value of induction coil to ensure the high stability of output voltage in the form of half periodic sine wave current. This series have the advantage of wide voltage-regulation range, high voltage-regulation precision and fast response. It can inhibit the noise and peak interference of state grid effectively. The pointers and digital display boards are optional for different users. With the high reliability and stable performance and the attractive appearance, it is one of the most popular models in AC power supply.
