IGBT induction heating power supply

Application: Applicable to: induction heating equipment, induction heat treatment production line control system
 IGBT heating power supply
Full automatic intelligent IGBT frequency conversion series induction power supply:
Technical parameters: 100kw-5000kw, 0.2khz-50khz, power factor > 0.95, cos Φ > 0.99 (any load matching)
Application fields: rolling heating, billet warming, quenching and tempering production line, forging, etc.

  IGBT induction heating power supply Functional features:
Adaptive frequency conversion: the adaptive range is 0.2khz-50khz. After process adjustment and load change, there is no need to open the cabinet door to adjust the power supply. The power supply frequency is automatically tracked and automatically hopped to the optimal resonant frequency of the load.
Adaptive load changing: after process adjustment and load change, the power supply and load automatically match to the best working state, achieving high production efficiency, quality consistency and equipment reliability.
Automatic power regulation: wide range of stepless regulation. YUANTUO automatic digital IGBT frequency conversion Induction heating power supply Through the power and temperature automatic control system to achieve accurate and stable control of heating temperature.
High power factor: under the condition of any load matching and full power output, the power factor is greater than 0.95, and there is no need for separate power compensation device, which can not only reduce equipment investment, but also reduce electricity expenses of users, improve power supply capacity, reduce high-order harmonics and improve power quality.
Quick start-up of 0.2 seconds under any load (no-load / full load) and any temperature (cold / hot state), 100% start-up success rate and 0.1% repetition accuracy.
Three closed-loop control modes of constant power / constant temperature / constant current can be switched arbitrarily.
The power supply can adapt to a variety of incoming line voltages (380V / 575v / 660V).

high reliability
Intelligent protection system: using special diode protection technology, never burning diode, using IGBT speed protection technology (nanosecond level), so that IGBT life is longer; transformer primary side, capacitor, output bus, furnace body two poles, turn to turn ignition protection; workpiece or billet and inductor contact ignition protection (grounding protection). Users can also choose customized power protection scheme according to various working conditions.
DSP digital control device, parameters are fixed in the program, environmental changes will not affect the internal parameters. The digital power supply has the advantages of high stability, fast transmission speed, high precision, easy process adjustment, etc.
Select international famous brand components, all optical fiber transmission signal, avoid interference, make power operation more stable.
Good anti voltage fluctuation performance: when the voltage fluctuation range is 350-440v, the output power fluctuation is ± 1 ‰, which does not affect the product quality.
