QS4E_4815S3U – GAPTEC

The QS4E_4815S3U is a galvanically isolated DC-DC converter module designed for point-of-load applications requiring a stable and regulated 15V output. It accepts a wide input voltage range of 43.2V to 52.8V (nominally 48V, ±10% tolerance), providing robust operation in environments with fluctuating power supplies. This module delivers a maximum output current of 16.6mA, resulting in a power output of 0.25W. Utilizing a high-frequency switching topology, the QS4E_4815S3U achieves a typical efficiency of 76% across its operating range. The isolation barrier is designed to withstand significant voltage differentials, enhancing system safety and reducing ground loop issues. Encapsulated for enhanced thermal management and environmental protection, the module operates reliably within a temperature range of -40°C to +85°C, making it suitable for demanding industrial applications.
