QT8B_1505S3UP – GAPTEC

The QT8B_1505S3UP is a galvanically isolated DC-DC converter module designed for point-of-load power applications. This module accepts a nominal 15V DC input (13.5V – 16.5V range, ±10% tolerance) and provides a regulated 5V DC output at 50mA, delivering 0.25W of power. Isolation is achieved through a high-frequency transformer, providing robust electrical isolation between the input and output stages. The unit exhibits a typical efficiency of 78%. It is designed for harsh environments, operating reliably across a wide temperature range of -40°C to +105°C. The module incorporates internal protection features, including short-circuit protection and over-temperature shutdown. The compact design and robust construction make it suitable for integration into a variety of embedded systems and industrial control applications. The isolated nature allows for breaking ground loops and ensures safety in sensitive applications.
