QS4E_1218S1U – GAPTEC

The QS4E_1218S1U is a compact, isolated DC-DC converter module designed for applications requiring a regulated 18V output from a nominal 12V (10.8V-13.2V) input. This single-output module delivers a tightly regulated 18V DC output at a current of 13.8mA, providing a power output of 0.25W. Galvanic isolation is incorporated to ensure electrical safety and noise immunity between the input and output stages. The converter achieves a typical efficiency of 74% across the specified input voltage range. The robust design allows for reliable operation within a wide temperature range of -40°C to +85°C, making it suitable for demanding industrial and outdoor environments. Internal circuitry incorporates protection against over-current and short-circuit conditions. The module is designed for PCB mounting and offers a stable and reliable power solution for sensitive electronic components.
