0-430V Three Phase Variac Transformer 220V Input 9KVA Adjustable Voltage Regulator

Our 9KVA three phase variac transformer with 220V input provides a continuously adjustable 0-430V three phase output for laboratories, workshops, and equipment testing stations operating on 220V line voltage. This TSGC2 series variable transformer is the ideal voltage regulator for facilities in regions where 220V three phase supply is standard, allowing precise manual adjustment of output voltage for motor testing, aging tests, lighting dimming experiments, and calibration work. The contact type design with double carbon brushes and pure copper windings delivers smooth stepless regulation, zero waveform distortion, and strong overload tolerance, while the compact reinforced metallic cabinet keeps the unit portable enough to move between test stations. With its intuitive rotary knob and digital display, operators can set and verify test voltages in seconds, improving laboratory throughput and measurement reliability.

• 220V Input Design: Purpose configured for 220V three phase mains, providing 0-430V adjustable output for laboratories and workshops that do not have 380V supply available.
• Stepless Smooth Adjustment: Precision double carbon brushes travel along polished pure copper coil surfaces, delivering infinitely variable voltage without steps, clicks, or output gaps.
• Clean Sine Wave Output: Contact type regulation introduces zero additional waveform distortion, keeping harmonic content low for sensitive instruments and precision measurements.
• Compact Portable Cabinet: The reinforced metallic enclosure with carrying friendly dimensions fits easily on laboratory benches and test carts, saving valuable floor space.
• Instant Overload Tolerance: Strong instantaneous overload capability handles motor starting currents and capacitor charging surges without tripping or output collapse.
• Clear Digital Monitoring: High definition digital display shows real time output voltage per phase, enabling accurate recording of test conditions and quick verification of settings.

This 220V input variac transformer serves a wide range of applications including motor running tests, electrical appliance durability testing, lighting fixture dimming evaluation, power supply calibration, and educational experiments in vocational schools and universities. It is also widely used by elevator maintenance teams, HVAC service workshops, and electronics manufacturers to simulate line voltage variations and verify equipment immunity to voltage fluctuation. Custom output ranges, panel layouts, and input configurations are available for OEM projects, and the unit can be supplied with additional metering, protection breakers, or remote control interfaces on request.

Standard packaging is a high strength carton for single units and a reinforced non fumigation plywood case for multiple units; the reference packing size is 24X28X60CM with a gross weight of approximately 40KG. Every unit is manufactured in our ISO9001 and CE certified plant and passes full inspection including winding resistance measurement, insulation testing, output linearity verification, and a 30 minute no load running test before shipment. We accept OEM/ODM orders with custom branding, offer a minimum order quantity of one unit, and provide lifetime technical consultation together with fast global delivery under all major Incoterms.
