TSGC2 9KW Three Phase Variac – Industrial-Grade Voltage Regulator & Variable Transformer for Precision Power Control

Overview:

The TSGC2 9KW Three Phase Variac is a precision-engineered, heavy-duty adjustable voltage transformer specifically designed for industrial and commercial-grade electrical applications. Built to regulate voltage with exceptional accuracy and reliability, this variac delivers stable, continuous, and distortion-free voltage output across a wide range of equipment, reducing energy waste, minimizing load fluctuations, and protecting sensitive components from voltage spikes or drops.

Unlike conventional fixed-output transformers, this manual voltage controller allows for fine voltage adjustments between 0V and the rated maximum (typically up to 430V) across all three phases, giving complete control to the operator for calibration, testing, or customized voltage output. Whether you're operating machinery, balancing power loads, or testing variable input devices, the TSGC2 offers seamless and responsive voltage control with exceptional thermal stability and overload protection.
