2. Basic Specifications of SP-15
Main Applications and Features:
The SP-15 series is widely used for heating small metal parts such as:
In the SP-15 series, a series oscillating circuit is used. The high-frequency transformer outputs low voltage and high current power through the induction coil. The SP-15 series was the first model developed by our company. It uses MOSFET components and our first-generation inverting control technology, making it easy to operate and maintain. These features contribute to its widespread use both domestically and internationally.

Working Principle and StructureIn the SP-15 series, a series oscillating circuit is used. The high-frequency transformer outputs low voltage and high current power through the induction coil. The SP-15 series was the first model developed by our company. It uses MOSFET components and our first-generation inverting control technology, making it easy to operate and maintain. These features contribute to its widespread use both domestically and internationally.

Advantages of Timer Function in SP-15A:
- Heating power, retention power, heating time, retention time, and cooling time can be set and adjusted, allowing precise control over the heating process.
- Ideal for repeated or high-speed heating of small parts.
- When used for brazing, proper timing parameters allow rapid heating and retention, ensuring even temperature distribution and smooth melting of the brazing material for strong joints.
- The high-frequency transformer is separated from the generator, connected via a 2-meter cable, enhancing flexibility and safety.
- Suitable for dirty or corrosive environments, with the generator placed in a clean area to improve reliability.
- The compact and lightweight design of the transformer makes it easy to integrate into production lines or mobile setups.
