1) Adopt good quality high frequency large power vacuum tube and high voltage vacuum capacitor to form resonant oscillator.
2) DC voltage regulating cabinet and high frequency oscillating cabinet can adopt integrated design for small power grade, or independent design for large power grade, which is convenient for layout at site.
3) Full digital AC voltage regulation control technology adopted, to ensure AC side 3-phase balance symmetry with small grid side non characteristic subharmonic content and high grid side power factor.
4) Vacuum tube self-oscillation circuit adopts optimal design, which has stable oscillation and high efficiency without parasitic oscillation, and suitable for ultrahigh Frequency induction heating field.
5) It has the perfect protection function of over voltage, over current, Loss of lock, temperature and water flow, with reliable operation and low failure rate.6) Adopt PLC and colorful touch screen to form the perfect friendly human-machine interface. Not only does It realize the communication control with user host computer by Ethernet or DP communication mode, but also it can achieve automatic logic control, fault display and fault diagnosis function of power supply system.
