QS4E_0509S1U – GAPTEC

The QS4E_0509S1U is a compact, galvanically isolated DC-DC converter module designed for point-of-load power applications. This unit provides a tightly regulated 9V DC output at 27.7mA, delivering a stable 0.25W of power. The input voltage range is specified as 4.5V to 5.5V, with a tolerance of ±10% accommodating minor voltage fluctuations. The module achieves a typical efficiency of 74%, optimizing power conversion and minimizing heat dissipation. Its robust design allows for reliable operation across a wide temperature range, from -40°C to +85°C, making it suitable for demanding industrial and embedded environments. Isolation is a key feature, providing electrical separation between the input and output stages, enhancing system safety and reducing ground loop issues. The single output configuration simplifies integration into existing circuit designs.
