TDGC2-0.5K Variable Transformer Single Phase

Description:

The TDGC2-0.5K Variable Transformer is a single-phase adjustable autotransformer used to provide continuously variable AC output voltage for testing, calibration, equipment startup, and laboratory applications. Commonly installed in electronics laboratories, repair facilities, manufacturing plants, educational institutions, and industrial maintenance departments requiring adjustable AC voltage output. Technicians and engineers use this unit for equipment testing, motor speed control, lamp dimming, transformer testing, and voltage simulation applications. The TDGC2 series utilizes a carbon brush moving across a toroidal winding to provide smooth stepless voltage adjustment without waveform distortion. 

Applications:

The TDGC2-0.5K variable transformer is commonly used for testing electrical equipment, powering prototypes, burn-in testing, motor and fan speed control, heater temperature adjustment, and laboratory experiments requiring variable AC voltage. Typical applications include electronics repair benches, educational laboratories, quality control departments, industrial maintenance shops, and production environments requiring controlled voltage adjustment from zero to above nominal line voltage.
