XP Power QHL300 DC/DC Converter, 28V DC Output, 10.7A, 180V to 425V DC Input, 300W, Through Hole, Half Brick Package QHL300

XP Power QHL300 DC/DC Converter model QHL300 is a high-performance 300W power module designed for effective voltage conversion in industrial and electronic applications. It features a regulated single output of 28V DC at a maximum current of 10.7A, capable of operating from a wide input voltage range of 180V to 425V DC. The converter is packaged in an industry-standard half brick through-hole format measuring 61mm in length, 57.9mm in width, and 12.7mm in depth, making it suitable for compact power supply designs.

This series is ideal for constructing distributed power architectures including AC front ends, Power Factor Correction (PFC) front ends, and battery-powered systems. The QHL300 series ensures system efficiency with a 90% typical efficiency rating, minimizing energy losses during operation. Output voltage can be trimmed between -20% to +10% allowing precise voltage adjustments required by sensitive equipment.

Electrical isolation of 3kV AC enhances safety and electromagnetic compatibility by isolating the input from the output. Other advanced features include remote On/Off control and protection against overheating, ensuring robust and reliable operation under varying thermal conditions ranging from -40°C to +100°C.

The device weighs only 90 grams, supporting portability and ease of integration without adding significant weight to the system. Its compact size and standard packaging facilitate seamless replacement or upgrade in existing power modules.

Applications include industrial machinery, telecommunications, instrumentation, and renewable energy systems requiring stable, isolated DC output power. This model is manufactured in Taiwan, Province of China, and offers a three-year warranty to guarantee performance and durability.
