The Magnetic Voltage Regulator is a solid-state, contactless power control device that enables smooth, stepless voltage adjustment for demanding industrial loads. Operating on the magnetic saturation principle and controlled by a small DC current, it eliminates mechanical wear and offers exceptional reliability. Available in single-phase (D), three-phase (S), and specialized Scott-connection (T for three-phase to two-phase conversion) configurations, it serves as a robust and precise executive component in automated control systems. It is ideally suited for applications requiring precise thermal management, such as various industrial furnaces, electroplating, and speed regulation.
Product Features
• Stepless & Contactless Regulation
Provides smooth, continuous output voltage control from zero to rated value without any mechanical contacts or moving parts, ensuring long life, minimal maintenance, and high reliability.
• Solid-State DC Control
Voltage adjustment is achieved by controlling a low-power DC current, enabling easy integration for manual, local electric, or fully automated closed-loop control via external signals (e.g., 4-20mA, 0-10V).
• Versatile Phase Configurations
Offered in Single-Phase (D), Three-Phase (S), and Scott-Connection (T) types. The Scott-connection model uniquely converts a three-phase supply to two independently controllable single-phase outputs for complex load requirements.
• High Reliability & Robust Design
The absence of arc-prone contacts and mechanical actuators makes it exceptionally reliable for heavy-duty, cyclic industrial operations. Features a rigid mechanical construction.
• Dual Insulation Platform
Oil-Immersed versions for higher voltage/capacity ratings or outdoor use, offering application flexibility.
• Ideal for Resistive & Thermal Loads
Specifically engineered for the stable, precise power control needed by salt bath furnaces, vacuum furnaces, electro-slag remelting furnaces, glass melting furnaces, crystal growers, and various resistance furnaces.

Packaging, Warranty & Certifications
Packaging:
Dry-type units are securely mounted on bases and wrapped with waterproof material, often placed in wooden crates. Oil-immersed units are shipped filled with oil under nitrogen, with external components crated separately. All units are clearly marked for lifting and handling.
Warranty:
We provide a standard 12-month warranty from the date of commissioning or 18 months from shipment, covering defects in materials and workmanship under normal operation.
Certifications & Testing:
Our production is ISO 9001 certified. Products are designed with reference to relevant electrical standards (e.g., IEC 60076 for reactors). Each unit undergoes critical tests including but not limited to: turns ratio, winding resistance, no-load & load characteristics at various DC control levels, impedance measurement, and dielectric withstand tests according to its voltage class.
