It features high power density and excellent heat dissipation performance. Its unique vertical structure design enables it to be directly welded or installed on the vertical PCB board of the power module, not only saving valuable floor space but also facilitating the formation of vertical heat dissipation airflow in the narrow ducts of the cabinet, significantly improving the thermal exchange efficiency and ensuring temperature stability during long-term full-load operation. It can adapt to various environments ranging from outdoor base stations to data center rooms, making it an ideal choice for building modern, highly reliable and modular communication power supply networks.

Designed specifically for modern high-density DC-DC power modules, the DC-DC Converter High-Frequency Transformer manufactured by Haoer Factory is a key magnetic component for achieving efficient voltage conversion and isolation in DC circuits. Its operating frequency can extend up to 500kHz. Thanks to the significant advantages brought by high-frequencyization, it allows for the use of smaller magnetic cores and fewer turns, thereby enabling the miniaturization and lightweighting of the converter module. It is widely used in vehicle power supplies, onboard power supplies, renewable energy systems, communication base stations, and industrial automation equipment, providing efficient, compact, and reliable isolated DC voltage solutions for distributed power supply architectures.

As the core power conversion component of an uninterruptible power supply (UPS) system, Haoer's UPS Power Supply High-Frequency Transformer is specifically designed to ensure continuous and pure power supply for critical equipment. Its core advantage lies in its extremely high power density and conversion efficiency, which can significantly reduce the size and weight of the entire UPS unit, while also lowering the no-load loss. For common input fluctuations, sudden load impacts, and harsh electromagnetic environments in UPS applications, an optimized magnetic path structure and rigorous winding process are adopted, featuring excellent anti-saturation capability, low leakage inductance, and outstanding EMI suppression characteristics, ensuring stable and reliable voltage conversion. The design strictly follows safety regulations, providing strong electrical isolation, with a working temperature range of -40°C to +125°C. It is the core component for power protection in critical fields such as data centers, medical equipment, industrial control, etc.
