Since most of textile equipment are installed in cotton-dusty and humid environment and usually voltage regulators are required to be near textile equipment, the voltage regulator of textile equipment designed by our company makes use of the structure of sealing inner air duct board. Auto temperature test control is applied to emit heat. The whole system is moisture proof to ensure continuous and normal operation of equipment in highly humid environment. It has the features of high precision of voltage regulation, good stability and flawless protection.
