Three phase 10-15kw digital electromagnetic Induction heating control board adopts high-speed optocoupler drive and Infineon IGBT module. It has the characteristics of stable performance, low failure rate, long service life and remarkable energy-saving effect. Support standard Modbus RTU communication protocol. It can be widely used in plastic machinery (such as energy-saving transformation projects of injection molding machine, wire drawing machine, granulator and extruder), food machinery, crude oil transportation, heating and other similar heating industries.
working principle
An electromagnetic Induction heater is a device that converts electrical energy into heat energy by means of electromagnetic induction. Electromagnetic Induction Heating Control Board will be 220 v / 380 v, 50/60 Hz alternating current (ac) by the rectifier circuit rectifier into direct current (dc), through the control circuit converts direct current (dc) into different frequency voltage, high-speed change of high-frequency electric current flows through the coil produces high-speed change of alternating magnetic field, When the alternating magnetic field lines in the magnetic field pass through the magnetically permeable metal (iron, cobalt, nickel) material, countless small eddy currents will be generated in the metal body. The metal material itself generates heat at a high speed, thereby achieving the purpose of heating the contents of the metal material barrel.
