JJW Series Precision Purifying AC Stabilized Voltage Supply
·Description
JJW (single phase) series is the precisely purifying AC power supply. 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.
·Application fields:
It is ideal for the voltage regulation and protection of the computers and peripherals; network broadcast equipment automatic assembly production line and modern high-tech productions in industrial and mining enterprises, transportation, schools, medical, hotels, scientific research lab, government agencies.
·Features
