3S7B_2412S3UP – GAPTEC

The 3S7B_2412S3UP is a compact, isolated DC-DC converter module designed to provide a tightly regulated 12V output at 250mA. This module accepts a DC input voltage within the range of 21.6V to 26.4V (±10% tolerance). It employs a high-frequency switching topology to achieve a typical efficiency of 81% across the input voltage range. The isolation barrier provides galvanic isolation between the input and output, enhancing safety and reducing ground loop issues. The device is designed for robust operation across a wide temperature range, from -40°C to +105°C, making it suitable for demanding industrial and automotive applications. The module utilizes surface mount technology (SMT) for reliable assembly and is designed for automated manufacturing processes. Overcurrent and short-circuit protection are integrated to ensure device longevity and system reliability. The low output ripple and noise characteristics further enhance its suitability for sensitive electronic loads.
