DSP intelligent induction heating power supply, using Kechuang unique intelligent "dynamic load analysis" technology. It overcomes the unstable problems such as low control precision, large reactive power loss, narrow frequency range, overcurrent, shutdown, frequency discomfort and so on, which are represented by "analog phase-locked loop" technology.The power supply can work stably between 5KW and 1000KW with frequency 0.5KHZ-600KHZ. The technology is in the leading position in China and internationally.
