At present, many regulators on the market are still mechanical carbon brush structure, although it has some advantages, but because of the use of mechanical transmission and carbon brush for adjustment, it has many disadvantages, such as short service life, poor reliability, long dynamic response time and so on, so it is being replaced by non-contact compensation regulator.

穩(wěn)壓器產(chǎn)品，在中國市場已有20多年的歷史，已廣泛應(yīng)用到工業(yè)、能源、交通、信息、航空、航運、國防、教育、文化等領(lǐng)域。穩(wěn)壓器的主要電路結(jié)構(gòu)，從最初的機械碳刷式，到目前流行的無觸點補償式，經(jīng)歷了好幾代的發(fā)展變化。

Pressurizer products have a history of more than 20 years in the Chinese market, and have been widely used in industry, energy, transportation, information, aviation, shipping, national defense, education, culture and other fields. The main circuit structure of voltage regulator has experienced several generations of development and change from the original mechanical carbon brush type to the current popular contactless compensation type.

無觸點補償式穩(wěn)壓器，它主要由隔離變壓器、SCR模塊、CPU控制核心、快速穩(wěn)壓技術(shù)和安全保護裝置組成，實現(xiàn)了全無觸點控制，安全、高效、節(jié)能、環(huán)保，是SCR開關(guān)技術(shù)和變壓器技術(shù)的完美結(jié)合。

The contactless compensation voltage regulator is mainly composed of isolation transformer, SCR module, CPU control core, fast voltage stabilizing technology and safety protection device. It is a perfect combination of SCR switch technology and transformer technology, which realizes full contactless control, safety, high efficiency, energy saving and environmental protection.
