Performance characteristics of DSP intelligent induction heating power supply （2）

7. Three-phase incoming surge absorbs dedicated line reactor, adjusts line impedance to suppress surge voltage, current and noise, and reduces harmonic pollution to the power grid.

8. The phase sequence of the three-phase incoming line is automatically recognized, and the phase sequence does not need to be adjusted.

9. Perfect protection circuits and measures, in addition to overcurrent and overvoltage protection, protection measures such as phase loss, overload, over temperature, water pressure, ground fault, frequency tracking loss of lock, complete functions, fast and reliable protection.

10. One-button quick start, simple operation, high stability, high control precision, and strong load adaptability. The power adjustment is only required by the machine tool. It only needs to press the start and stop buttons during production. If it is connected to the machine tool, it can be automatically produced according to the program.

11. 100% startup success rate, avoiding local leakage quenching of large workpieces or quenching of batch workpieces, the power can be smoothly and continuously adjusted (10～100% rated power), load adopts parallel inverter resonant circuit, simple circuit, reliable operation, and convenient adjustment. Wide application range, suitable for intermittent and long-term work system, to meet the needs of industrial sites.

12. Control system single board: it is easier to control than multi-board of traditional induction heating equipment, easy to operate by debugging and maintenance, and adopts SMT manufacturing process. The size of the main board is greatly reduced, avoiding the contact points caused by the combination of multiple control boards and the problem of higher failure rate, so that it has good stability and trouble-free ability.

13. The power supply layout adopts water system and electricity system separation system, to avoid the danger of inadvertent water leakage to the power supply equipment, and improve safety and reliability.

14. The electric control cabinet uses the industrial special air conditioner to adjust the temperature and humidity of cabinet inside.
