QS4E_4807S3U – GAPTEC

The QS4E_4807S3U is a galvanically isolated DC-DC converter module designed for point-of-load applications requiring a tightly regulated 7.2V output. This module accepts a wide input voltage range of 43.2V to 52.8V (nominal 48V ±10%). It delivers a single output of 7.2V at a current of 34.7mA, providing a maximum output power of 0.25W. The converter employs a fixed-frequency switching topology to achieve a typical efficiency of 76% across the input voltage range. Integrated isolation provides robust protection against ground loops and voltage transients. The module is designed for reliable operation in harsh environments, with a wide operating temperature range of -40°C to +85°C. It features internal filtering to minimize EMI and RFI, and is suitable for applications requiring compliance with relevant EMC standards. The QS4E_4807S3U offers a compact and efficient solution for powering sensitive analog and digital circuitry.
