The Single Phase Variac Manual Close Type is a high-precision voltage regulating device designed to provide smooth, stepless adjustment of AC voltage from a single-phase power supply. It is commonly used in laboratories, industrial testing facilities, R&D departments, and service workshops where controlled and variable output voltage is required.
This close-type variac is enclosed in a protective housing, offering enhanced safety, reduced exposure to live parts, and improved durability compared to open-type models. It features a manual rotary control knob for accurate voltage adjustment and is built with high-grade copper winding and a robust toroidal core for efficient and stable performance.
