The Longli TDGC2J/TSGC2J series contact voltage regulator user manual provides specifications, installation, wiring, operation, and maintenance instructions.
The TDGC2J/TSGC2J series contact voltage regulators are energy‑saving devices made from imported silicon steel sheets. They offer undistorted waveforms, high efficiency, low loss, low temperature rise, and are used in industrial, scientific, utility and household applications for voltage, temperature, speed, dimming and power control.
The manual covers product models, basic parameters, rated output capacity, insulation class, overload capability, operating principle, main structure, environmental requirements, pre‑installation checks, wiring diagrams, safety precautions, regular maintenance and ordering information. This manual is written in Chinese.
