working principle
An electromagnetic Induction heater is a device that converts electrical energy into heat energy by means of electromagnetic induction. Electromagnetic Induction Heater 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.
The key to choosing an electromagnetic Induction heater depends on these four points
1,Specialization: DSP high-speed operation control, digital programmable technology, high-speed optocoupler drive, open hardware architecture
2,Stable performance: The half-bridge IGBT module is used as the main circuit structure, which can save power by 30% ~ 80%, and the thermal efficiency can reach 95%, which can be customized:
3,Worry-free after-sale: one year warranty, professional technical staff guidance, lifetime cost maintenance of wearing parts, after-sales customer service one-to-one tracking service:
4,Quality assurance: 15 years of careful development, EU CE certification, ISO9001 quality management certification
