Product Introduction
The main transformer of this high-frequency DC power supply is an efficient and energy-saving transformer independently developed by Tongke Electric. It uses nanocrystalline soft magnetic materials as the main transformer core, with a large overcurrent area, good cooling effect, excellent coupling, and low operating losses, ensuring the service life of the power supply; The main power component of the power supply is a high-power original imported Infineon insulated gate bipolar transistor IGBT module, with high-quality material selection to ensure quality. The output mode is full bridge full wave output, PWM control. This high-frequency DC power supply is suitable for fields that require high-quality DC power such as electroplating, electrolysis, oxidation, water treatment, electrophoresis, hydrogen production, rare earth smelting, etc.
