Zhejiang Yiyuan Electric Company Ltd., is a Chinese enterprise, specializing in electrical power supply related products. We provide a wide range of products for electric power supply systems, communication systems, and automatic control systems. Our primary products include: automatic voltage regulators (AVRs) (SVC single phase AVR; relay type AVR; SVC & SBW Three Phase AVRs, contact voltage regulators, etc.), uninterrupted power suppliers (UPSs) (or battery back-ups), inverters (sine wave inverters, solar inverters, etc.), battery chargers & solar charge controllers, transformers (control transformers and round transformers).

Eyen AC voltage regulators are produced to the strictest standards, and have the highest reliability. Our electrical regulators are commonly used in industrial and mining enterprises, oil fields, railways, as well as elevator lighting or any location needing a stable power supply. UPS (uninterruptible power supply) is used primarily to provide emergency power when utility power is not available. Eyen online UPS and offline UPS (or standby UPS) are used to protect computers, data centers, telecommunication equipment, or other equipment where an unexpected power disruption could cause injuries, business disruption or loss of data. Some of our other electrical devices, like inverters (power inverters ), are widely used to convert direct current (DC) to alternating current (AC) or used in solar energy systems. Our battery chargers are used to put energy into a secondary cell or battery by forcing an electric current through them; while voltage transformers are use for transferring electrical energy from one circuit to another through the electrical transformer's coils.

As a result of our attention to product quality and reliability, our AC voltage regulators (AVRs), UPSs, sine wave inverters , chargers, and control transformers have received CE and ISO9001 certificates. This, in addition to our economical prices and customer service, has helped our products to gain popularity globally, and in increasing amounts. Our annual production has now reached 10 million.
