SCWY (CWY) series of purification AC parameter stabilized voltage power supply is made on the principle of sine energy distribution, which is a new product from the improvement of the company's JJW (JSW) precision purification AC voltage regulation. It is one of the AC stabilized voltage power supplies, currently popular in the world. The controller responses rapidly and preciously on the load change in input voltage and output end; and adjusts timely the compensatory voltage on the sine energy distributor to effectively control the output voltage. Thus, the whole device has a high accuracy of voltage regulation and excellent dynamic property. With the added filer of large capacity, it effectively suppresses the high order harmonic, peak voltage, and the noise interference signal, combining as one the output waveform more pure and integrating the voltage regulation, purification, interference resistance, and automatic protection. It is one of advanced stabilized voltage power supplies at present.
   The product is broadly used in all the places needing voltage regulation, such as computer related products, medical monitoring and controlling system, program controlling system, auto measuring equipment, broadcasting and TV equipment, equipment for post and communications, auto plug-in devices, production line, printing equipment, plastic injection equipment, automatic teller machine, SMT equipment, and scientific experiment, etc.

ZDBW and ZSBW series of complementary AC voltage regulator of single phase and three phases, and intelligent purification is the latest AC voltage regulator of high power, designed by the company with the imported foreign new technology of AC voltage regulator and according to the domestic situation. It integrates as one the complementary style and contactless switch, and the technology of AV voltage regulation controlled by the microprocessor. It has the characteristics of high efficiency of energy saving, fast regulation, noiseless, automatic balance of the three phases, no mechanical failure and carbon brush wear, and long operation life. It also has the functions of time delaying, alarming and protecting against over and under voltage. At the same time, the regulator has outstandingly solved the problems of costae current impact to the contactless switch in the transient process during the system and the components and the components damage caused by the over voltage. Its strong instant over loading capacity increases remarkably the reliability of the system operation.
      The product can be used broadly in places needing stable voltage, such as industrial automation, plant equipment, numerical controlled machine, textile and other light industries, medical treatment, hotel, broadcasting and TV, the communication equipment. With the computer remote communication interface, it can realize the remote power supply control, remote communication, and remote measuring.

CWY-J series of parameter AC stabilized voltage power supply is a stabilized voltage power supply of new generation absorbed the domestic advancing experience, which can meet the requirements of the high performance and high reliability of the power supply in military industry, railway, aviation, medical treatment, post and communications, broadcasting and TV, etc. With the precious design of the nonlinear parameters of the electrical and magnetic system, this series of the power supply meets the resonance and stability conditions for the rapid, high effective, and stable transmission of the energy. It has overcome various serious disadvantages of idle consumption of high current, low efficiency, high temperature increase, and waveform distortion of magnetic saturation and constant voltage transformer. At the same time, it has also overcome the disadvantages of long strain time, narrow voltage regulation range, short operation life, and easy over voltage output of the 614 series of electronic AC stabilized voltage power supply and other power supplies. There are controlling circuits consisting of transistors and other electronic components within the power supply. The input and output are isolated completely for high reliability, and strong interference resistance and over load. It has the advantages of not facing the danger of over voltage at the output end and bearing the short circuit at the output end. The series of power supply is broadly used in various kinds of high precision and advanced electronic equipment for isolation, interference resistance, and high precision stabilized voltage power supply. It is also suitable to normal electronic equipment used as a stabilized voltage power supply of high quality.

ZJY series of automatic AC stabilized voltage power supply is a popularized AC stabilized voltage power supply. Its mainly consists of the contacting self-coupling voltage regulator, servo motor, and automatic control circuit. When the input city electricity varies, the control circuit monitors and tests it, while outputing a control signal to the servo motor to adjust the carbon brush onto the self-coupling voltage regulator position to ensure the stability of the output voltage. The power supplies above 2KVA is equipped with an over voltage protection device, which automatically cuts off the load of the voltage protection when the output voltage is higher than the rated value.
