3S7BE_0509S3U – GAPTEC

This isolated DC-DC converter module, designated 3S7BE_0509S3U, provides a regulated 9V DC output at 333mA, delivering 3W of power. It accepts a tightly controlled input voltage range of 4.75V to 5.25V (±10% tolerance). The module incorporates robust galvanic isolation between the input and output stages, enhancing system safety and mitigating ground loop issues. High efficiency, typically 90%, minimizes heat dissipation and maximizes power delivery to the load. The converter is designed for operation across a wide temperature range, from -40°C to +85°C, making it suitable for demanding industrial and embedded applications. Internal filtering minimizes EMI emissions, and comprehensive protection features, including over-current and short-circuit protection, ensure reliable operation and prevent damage to the module and connected circuitry. The compact form factor facilitates easy integration into space-constrained designs.
