Single Phase Variac Manual Open Type
The Single Phase Variac Manual Open Type is a precision voltage control device designed to provide smooth, stepless adjustment of AC output voltage from a single-phase supply. It is widely used in laboratories, testing facilities, industrial R&D setups, and electrical workshops where variable voltage is required for testing, calibration, and equipment development.
This open-type variac is manually operated using a rotary knob, allowing users to precisely control output voltage with high accuracy. Built with high-quality copper winding and a robust toroidal core, it ensures low losses, smooth operation, and long service life. The open design allows easy access for maintenance and efficient heat dissipation.
