1,Industry-leading wide inductance design: Electromagnetic induction heating system adopts a wide range of adjustable inductance design (inductance range: 1μH ~ 600 μH), covering low inductance (precision local heating) to high inductance (large volume penetration heating), suitable for a variety of industrial scenarios, through the self-adaptive resonance control technology, to ensure that under different loading conditions (eg, metal materials, size changes) can achieve high efficiency of the energy coupling, and significantly improve the compatibility of the system and heating efficiency. Heating efficiency.
2, Integrated isolation transformer:
The use of nanocrystalline magnetic core reduces high-frequency eddy current loss and improves efficiency; the isolation transformer can effectively reduce the noise generated by the high-frequency inverter and minimize the electromagnetic interference to the power grid; at the same time, it isolates the output port from the power grid and increases the safety of the output.
3,Accurate temperature control, improve process quality
± 3ºC (maximum 1±ºC ) high precision temperature control,
suitable for semiconductors, precision metal heat treatment and other demanding scenarios. Non-contact heating to avoid oxidation, deformation, to ensure stable material performance. 4,High stability and comprehensive failure mechanism
Can be continuous 24h all-day full load continuous work, while meeting the power grid± 20% fluctuations (three-phase 400VAC models) in the case of work, with over-voltage, over-current, phase failure, over-temperature and other protection mechanisms.
5, Safe and reliable industrial-level protection design Medium frequency induction heating power supply adopts independent air-cooled or water-cooled structure, PCB and so on adopts three-layer three-proof paint process, which can be applied to complex environments such as offshore platforms.
6,Data storage
The heating temperature curve can be displayed in real time and stored in the system, and the heating data can be queried in real time at any time or the U disk can be used to copy the historical heating data after the end of heating.
7,Multi-segment process curve
The system has constant power, power time curve, constant
temperature (constant temperature operation module is optional) and temperature time curve and other control modes, which can be selected according to different working conditions and needs.
8,Remote control (customized module)
The equipment integrates WiFi/5G wireless, RS485, TCP/IP MODBUS and other communication modules, which can be remotely monitored and controlled.
10, Diversified power control modes
The output power can be controlled by 0-10V, 0-5V, 4-20MA, digital regulation and so on.
application:
Ring seam welding heat/post-weld heat treatment
1, The C-type induction coil workpiece is fixed on the electric trolley, and the inductor can be controlled to lift and retract by controlling the movement of the electric trolley.
