Product Title: Medium Frequency Induction Heating Power Supply (SWI Series)
Product Description:
The SWI Series Medium Frequency Induction Heating Power Supply designed and produced by sinowin industry – a cutting-edge thermal solution designed to enhance your heating applications with unparalleled efficiency and reliability.
The SWI series medium frequency induction heating power supply produced by sinowin industry stands out due to its utilization of all-solid-state IGBT technology, providing precise frequency control and power adjustment. This innovative design incorporates comprehensive protection features such as overcurrent protection, low-water protection, overheating protection, overvoltage protection, short-circuit protection, and phase loss protection, ensuring the utmost reliability and facilitating maintenance.
With an intuitive display functionality showcasing frequency, current, voltage, and power status, operators can easily monitor the device’s operating conditions. This enhanced visibility assists in optimizing the design of the induction coil and capacitor adjustments, promoting a more effective heating process.
Notably compact and lightweight, the SWI series medium frequency induction heating power supply saves clients up to 10 times the production space compared to conventional thyristor-based systems. Capable of operating continuously at full load for 24 hours, this power supply delivers high efficiency and energy savings across all power ranges, boasting excellent power factor and source efficiency.
The SWI series induction heating furnace is constructed with a parallel resonant circuit that allows for versatile applications, including direct output configurations. Its fundamental structure integrates a medium frequency power supply, capacitor, and induction coil, making it perfectly suited for common applications like medium frequency forging furnaces and melting furnaces. This simplicity reduces loss, elevates operational efficiency, and minimizes manufacturing costs.
In scenarios requiring long induction coils, typically constructed from 3 to 10 meters of copper tubing, the SWI medium frequency power supply delivers a compelling voltage output of 550V directly to the induction coil. Note that since this design does not isolate from the main power supply, it is imperative that the induction coil is well insulated and not exposed to external elements.
Generally regarded as a standard product, the medium frequency induction heating power supply produced by sinowin industry automatically follows a frequency range of 1–20 kHz. Customized designs for the capacitor box and induction coil can be engineered based on the specific heating workpieces and requirements, achieving optimal heating effects and efficiency.
