Industrial Test Bench 30KVA Three Phase Variac Transformer 0-560V Adjustable

Our 30KVA three phase variac transformer is a high power adjustable voltage regulator engineered for industrial test benches, motor repair workshops, and large scale aging test facilities. This TSGC2 series variable transformer delivers a continuously adjustable 0-560V output from a 380V three phase input, with enough capacity to drive large motors, compressors, pumps, and complete production line sections under controlled voltage conditions. The heavy duty design features oversized pure copper coils, high conductivity double carbon brushes, and a reinforced metallic cabinet that withstands the rigors of round the clock industrial operation. With zero waveform distortion, strong overload tolerance, and ±1% output precision, this variac transformer gives plant engineers and quality managers the confidence to perform accurate testing, troubleshooting, and voltage sensitivity analysis on high power equipment.

• High Power 30KVA Capacity: Supports testing and voltage conditioning of large motors, compressors, and industrial machinery with continuous full load operation and generous overload margin.
• 0-560V Wide Adjustment Range: Stepless three phase output from zero to 560V allows complete voltage sweep testing, brownout simulation, and overvoltage verification in a single installation.
• Zero Distortion Power Path: Contact type carbon brush regulation preserves waveform purity, ensuring that test results are attributable to the equipment under test and not the power conditioning source.
• Durable Heavy Duty Build: 100% pure copper coils with microcomputer modulation control, high insulation terminals, and premium raw materials guarantee decades of reliable service in demanding industrial environments.
• Precise Stable Output: ±1% output precision and high conductivity double carbon brushes deliver stable voltage even when the load current changes rapidly during motor startup and shutdown.
• Operator Friendly Monitoring: High definition digital display with per phase voltage readout and smooth rotary control makes high power testing safe, simple, and repeatable for daily operators.

This 30KVA variac transformer is the power core of industrial motor test benches, transformer repair and rewinding shops, pump and compressor performance laboratories, and large appliance aging test lines. It is also deployed in railway maintenance depots, mining equipment workshops, and power plant auxiliary testing facilities where adjustable three phase voltage is essential for commissioning and fault diagnosis. The unit can be customized with higher output ranges, remote control, motorized adjustment, and integration into automated test systems for production line quality control, making it a versatile investment for organizations that test electrical equipment at scale.

Heavy units are packed in reinforced non fumigation plywood cases with internal bracing and foam protection; the reference packing size is 35X40X75CM with a gross weight of approximately 90KG. Our factory is certified to ISO9001 and CE standards, and each transformer undergoes full process inspection from incoming material to pre shipment testing, including insulation resistance, turns ratio, output linearity, and temperature rise verification under rated load. We provide OEM/ODM services, a minimum order quantity of one unit, flexible lead times of 3 to 15 working days depending on configuration, and lifetime technical support with optional on site engineering service.
