QS4E_1512S3U – GAPTEC

The QS4E_1512S3U is a compact, galvanically isolated DC-DC converter module designed for point-of-load applications requiring a stable 12V output. This module accepts a wide input voltage range of 13.5V to 16.5V (±10% tolerance around a nominal 15V input), providing a regulated 12V output at 20.8mA, delivering a total power of 0.25W. Isolation is a key feature, providing robust electrical separation between input and output stages. The converter achieves a typical efficiency of 76%, minimizing power losses and heat dissipation. It is designed for reliable operation across a broad temperature range of -40°C to +85°C, making it suitable for demanding industrial environments. The module utilizes a switching regulator topology to achieve high efficiency and tight output voltage regulation. Internal protection features include short-circuit protection and over-temperature shutdown.
