Power factor above 0.98, no need reactive power compensation equipment.

20% energy saving compared to the same capacity general electric furnace.

Control system

The main control system has a perfect dual protection mechanism:When the system is running normally, the main control board will monitor direct voltage, direct current, inverter voltage, inverter current, induction coil voltage, working voltage of electric capacitor, thyristor closing time and cooling system water temperature, etc. When one of them exceeds its preset protection value, the main control board will automatically limit the continuous change of this parameter to ensure the reliable and safe operation of the system.

If a parameter exceeds 20% of the preset protection value and does not automatically limit the parameter, the trip protection will work quickly to turn off the system to protect the safety of the equipment and the original.

Main feature:

  • High power output accuracy, error less than 1%.
  • Short power rise time.
  • Operation is very simple, only start/stop button and power dial, don`t need other adjustment.
  • phase loss protection of the main circuit
  • Short circuit protection of main circuit.
  • overvoltage protection of the silicon controlled.
  • Cooling water overtemperature protection.
  • Cooling water pressure is too low to protect.
  • Ground/leakage protection.

In addition to these protection systems, the following limits are also set:

  1. Full power limit;
  2. Capacitor voltage limit;
  3. Induction coil voltage limit;
  4. Output current limit;
  5. Frequency limit;

These protective systems and limits ensure that the induction melting system works safely and reliably.
