Products Description
IGBT medium frequency power supply is a constant-power-output special power supply for induction heating. It is mainly matched with melting furnaces, forging heating furnaces and heat treatment quenching equipment as a replacement for conventional thyristor medium frequency power supplies, widely applied in various processes including metal smelting, hot forging and thermal processing. Optimized in control system, circuit structure and matching induction coil, the product boasts prominent advantages in energy consumption, grid compatibility, maintenance cost and operational stability.
Core Product Advantages
Intelligent Control System
Equipped with an intelligent electric control system, the power supply realizes 24-hour real-time monitoring of overall operating data and supports remote startup/shutdown as well as remote parameter adjustment. A built-in automatic fault diagnosis system pinpoints faulty positions once abnormal conditions occur. Multiple sets of production programs can be customized and stored based on workpiece materials and processing techniques to precisely lock all process parameters, eliminating repeated parameter debugging when switching production items.
Modular Structure with High Cost Performance
The whole machine features optimized structure and independent modular layout. Faulty individual modules can be detached and replaced separately to cut maintenance time and reduce production line downtime significantly. For future capacity expansion, users can expand total output power by adding extra power modules instead of purchasing brand-new equipment, lowering equipment upgrading investment cost.
High-reliability Hardware Configuration
Adopting high-speed IGBT protection technology at core components, the unit protects internal parts instantly against sudden load change and short circuit to extend service life. Fitted with DSP digital control components, the full-digital circuit control delivers strong resistance against voltage and load fluctuation, ensuring stable operation and low failure rate.
Energy-saving & Eco-friendly with Excellent Grid Adaptability
The power supply generates extremely low harmonic content and features high power factor, requiring no extra reactive power compensation device during on-site installation. Designed with series resonant inverter, full-bridge rectifier plus LC filter circuit, it consumes less power than traditional thyristor counterparts and emits minimal high-order harmonics to avoid public power grid pollution.
Special Advantages of Circuit & Rectifier Design
Low-consumption fully-automatic composite parallel models adopt half-controlled rectifier structure. DC voltage stays at a constant high level during operation without conduction angle adjustment, fundamentally eliminating high-order harmonic generation. It causes no pollution to power grids and transformers, keeps switch components from overheating, and avoids operational interference to other on-site equipment such as air compressors and machine tools.
With constant power output characteristic, the equipment maintains full-power operation even under low feeding volume inside furnaces, delivering stable heating speed for workpieces and improving overall production efficiency of processing lines.
