QS4E_1509S3U – GAPTEC

The QS4E_1509S3U is a compact, isolated DC-DC converter module designed for providing a regulated 9V output at 27.7mA, delivering a maximum power of 0.25W. This module accepts a DC input voltage ranging from 13.5V to 16.5V, representing a ±10% tolerance around a nominal 15V input. Isolation is incorporated to electrically separate the input and output stages, enhancing system safety and reducing ground loop issues. The converter boasts a typical efficiency of 76% across its operating input voltage range. Constructed with robust components, the QS4E_1509S3U is designed for reliable operation across a wide temperature range, from -40°C to +85°C, making it suitable for demanding industrial and embedded applications. The isolated design and wide temperature range make it ideal for sensitive analog and digital loads requiring stable and clean power.
