QT8A_1205S3UP – GAPTEC

The QT8A_1205S3UP is a compact, isolated DC-DC converter module designed for point-of-load applications requiring a regulated 5V output at 50mA. It accepts a nominal 12VDC input (10.8V to 13.2V range, ±10% tolerance) and delivers a stable 0.25W output. Isolation between the input and output is provided via a transformer-based topology, enhancing system safety and reducing ground loop issues. Key performance metrics include a typical efficiency of 78% across the input voltage range. The module is designed for robust operation in harsh environments, with an operating temperature range spanning -40°C to +105°C. Internal protection features include short-circuit protection and over-temperature shutdown. The device utilizes surface mount technology to ensure high reliability and compact footprint. The converter is suitable for applications requiring galvanic isolation and precise voltage regulation in industrial control, instrumentation, and telecommunications equipment.
