Motor Testing 15KVA Three Phase Variac Transformer 0-560V Adjustable 380V Input

Our 15KVA three phase variac transformer is a heavy duty adjustable voltage regulator purpose built for motor testing, electrical laboratory work, and production line voltage simulation. Based on the proven TSGC2 series contact type variable transformer design, this unit steps up from a 380V three phase input to a continuously adjustable 0-560V output, giving test engineers complete control over the voltage applied to motors, drives, and electrical apparatus under evaluation. The variac transformer uses high conductivity double carbon brushes running on precision wound pure copper coils, delivering smooth, stepless adjustment with zero additional waveform distortion. Rated for continuous full load operation, it comfortably handles resistive, inductive, and capacitive loads, making it an indispensable tool for motor manufacturers, university laboratories, and quality inspection centers that demand accurate and repeatable test conditions.

• Wide 0-560V Adjustable Output: Continuously variable three phase output from zero to 560V with a smooth rotary control, covering the full test voltage envelope for motor rated voltage, overvoltage, and undervoltage experiments.
• Zero Waveform Distortion: Contact type carbon brush regulation preserves the sinusoidal waveform shape, so test results reflect the true behavior of the equipment under test rather than artifacts of the power source.
• High Precision Regulation: ±1% output precision with high conductivity double carbon brushes ensures stable, repeatable voltage settings for sensitive measurement and calibration procedures.
• Full Capacity Continuous Duty: Rated 15KVA for continuous operation with strong instantaneous overload tolerance, supporting locked rotor tests, inrush current tests, and other demanding motor testing procedures.
• Robust Industrial Construction: 100% pure copper coils, high insulation reinforced terminals, and a reinforced metallic cabinet deliver long service life with minimal maintenance even in daily laboratory use.
• Real Time Digital Display: High definition digital display shows the output voltage of each phase, allowing operators to monitor and document test conditions with confidence.

This 15KVA variac transformer is the standard voltage source for motor performance testing, variable frequency drive input simulation, transformer ratio testing, electrical appliance type testing, and aging test benches in manufacturing plants. It is equally at home in university power electronics laboratories, vocational training workshops, and third party inspection laboratories where adjustable three phase voltage is required for experiments and certification testing. The unit also supports customized output ranges and panel configurations, allowing integration into customer designed test systems and automated test equipment.

Each unit is shipped in a reinforced non fumigation plywood case with foam cushioning; the reference packing size is 28X32X65CM with a gross weight of approximately 55KG. Our ISO9001 and CE certified factory performs multi stage quality inspection from incoming copper and silicon steel materials to final pre shipment testing, including insulation resistance, voltage regulation linearity, and carbon brush contact checks. We offer OEM/ODM customization, a minimum order quantity of one unit, standard delivery of 3 to 7 working days, and lifetime free technical support with optional on site commissioning.
