The multifunctional microcomputer 3.5kW/220V Induction Heater uses the principle of electromagnetic induction heating to convert electrical energy into thermal energy. Firstly, the 50Hz AC power is converted into DC power through an internal rectification and filtering circuit, and then the DC power is converted into high-frequency high voltage power with a frequency of 17-30KHz through a PFM control circuit. The rapidly changing current passing through the coil generates a rapidly changing magnetic field. When the magnetic field lines in the magnetic field pass through the heated metal object, countless small eddy currents are generated inside the heated metal object, causing it to heat up at high speed.
Our induction heater technology is engineered for exceptional performance and reliability, offering a powerful solution for various heating applications. Unlike traditional methods, this advanced induction heater provides a more efficient and precise heating experience.
At the core of our induction heater is a sophisticated digital signal processor (DSP) control system that uses a phase-shift algorithm. This innovation ensures precise heating control and achieves a thermal efficiency exceeding 96%. This means more of your energy is converted directly into heat, making our induction heater an incredibly cost-effective choice.
Each induction heater is equipped with multiple layers of protection to ensure safe and reliable operation. This includes technologies for overcurrent, overvoltage, undervoltage, and interlock protection, safeguarding the system and your workspace. The power supply for the main control system is built with high-performance, surface-mount components, ensuring consistent and stable performance.
The power input section of this induction heater features multi-stage inductance filtering, which significantly enhances the reliability of multi-machine control setups.
Our commitment to quality is evident in every part of our induction heater. We use high-quality Infineon IGBT modules from Germany, and we reserve a 50% margin to guarantee a long product lifespan. The resonant capacitors and three-phase rectifier bridge stacks have undergone over 10 years of rigorous testing, proving their durability.
For optimal cooling, the radiator material is 30% more effective than similar products on the market, with the controller itself being 25% heavier. This robust design, combined with high-speed DC fans imported from Taiwan, ensures our induction heater maintains peak performance without overheating.
Our dedicated R&D team is constantly upgrading our induction heater products, integrating the latest advancements to meet the evolving needs of our customers. When you choose our induction heater, you are choosing a product backed by continuous innovation and a commitment to quality.
