The high-frequency DC power supply is based on high-quality imported IGBT as the main power device, and the ultra-microcrystalline (also known as nanocrystalline) soft magnetic alloy material is the main transformer core. The main control system adopts multi-loop control technology, and the structure adopts salt-proofing. Fog acidification measures. The power product has a reasonable structure and high reliability. The power supply has become a new generation of thyristor power supply with its small size, light weight, high efficiency and high reliability. Suitable for various precision surface treatment sites such as experiment, oxidation, electrolysis, galvanizing, nickel plating, tin plating, chrome plating, photoelectric, smelting, chemical formation and corrosion. It has also been well received by users in anodizing, vacuum coating, electrolysis, electrophoresis, water treatment, electronic product aging, electric heating, and electrochemistry. Especially in the field of PCB, electroplating and electrolysis, it has become the power supply of choice for many customers.
