Introduction 

 JJW (JSW) series precision purifying AC power supply with international advanced energy distribution program sinusoidal power conditioning technology and network technology combined with efficient broadband integrated filter made of. AC voltage regulator technology represents the latest development, the main power circuit consists of sinusoidal components distributor and power filter in parallel, when the AC input voltage or load current changes, the energy distributor in the sine half cycle sine wave current form, the energy required to accurately input to the inductor, the inductance of the inductor to adjust to ensure that the output voltage accuracy and stability. 
 This series of power supply has a voltage range, voltage regulator, high precision, fast response, long-term advantages of continuous work, and can effectively inhibit the sound and voice network in a variety of peak interference, is the purifying AC power supply products in the most welcomed by users of the preferred models. The products are widely used in computers and peripheral equipment, medical electronic equipment, communications radio equipment, industrial electronic equipment, automatic production lines and other modern high-tech products, regulation and protection.
