QS4E_1518S3U – GAPTEC

The QS4E_1518S3U is a compact, galvanically isolated DC-DC converter module designed for point-of-load applications requiring a stable 18V output. It accepts a DC input voltage ranging from 13.5V to 16.5V (±10% tolerance), providing a regulated single output. The module delivers a maximum output current of 13.8mA, corresponding to a power output of 0.25W. Isolation is implemented to provide electrical separation between the input and output stages. The converter exhibits a typical efficiency of 76% across its operational range. This module is designed for robust performance in harsh environments, with an operating temperature range spanning -40°C to +85°C. Internal protection circuitry is incorporated to enhance reliability and prevent damage from over-voltage or short-circuit conditions. The QS4E_1518S3U is suitable for applications demanding a small footprint, high isolation, and reliable DC power conversion within a specified temperature range.
