Sanken inverter was the first inverter brand to enter the country in the 1980s. Even when inverters were introduced from Japan to the country, there was no corresponding Chinese name. The deputy director of Sanken Lida Miss Changlu named it motor variable speed regulator, or inverter for short, according to English. Old experts in these historical industries are very clear and familiar with it.

The earliest Sanken inverters were produced in Japan and were introduced to the country by Hong Kong Lida Enterprises as the domestic general agent. At that time, the country was still not very familiar with inverters. Miss Lu and her seniors at that time spent a lot of time After a lot of experience in publicity and talent cultivation, frequency converters were gradually accepted. Most of Sanken's overseas employees are now active in many famous inverter manufacturers and have become the backbone of the inverter industry.

In 1999, Sanken Lida (Jiangyin) factory was established. Introducing Japan's inverter technology, quality assessment system, and production management into the country, it is controlled by Japan Sanken Co., Ltd. to produce Sanken inverters.

Therefore, inverters after 1999 were produced in Jiangyin, and many inverters before 1999 are still in use, and those should be produced in Japan.
