QS4E_2412S3U – GAPTEC

The QS4E_2412S3U is a compact, galvanically isolated DC-DC converter module designed for embedded systems requiring a regulated 12V output. It accepts a wide input voltage range of 21.6V to 26.4V (nominally 24V ±10%), providing a stable 12V output at 20.8mA. The module delivers 0.25W of output power with a typical efficiency of 76%. Isolation is achieved through a high-frequency transformer, offering robust protection against ground loops and voltage transients. The device operates across a wide temperature range of -40°C to +85°C, making it suitable for harsh industrial environments. Internal protection features include short-circuit protection and over-temperature shutdown, enhancing system reliability. The QS4E_2412S3U is optimized for low noise operation and features a small form factor for space-constrained applications.
