QS4E_2403S1U – GAPTEC

The QS4E_2403S1U is a single-output, isolated DC-DC converter module designed for point-of-load applications requiring stable 3.3V power. This module accepts a wide input voltage range of 21.6V to 26.4V (nominally 24V ±10%). It delivers a regulated 3.3V output at a maximum current of 75.7mA, providing a power output of 0.25W. Isolation between the input and output is provided for enhanced safety and noise immunity. The converter achieves a typical efficiency of 74% under nominal operating conditions. The QS4E_2403S1U is designed for robust operation in harsh environments, with a wide operating temperature range of -40°C to +85°C. This makes it suitable for industrial, telecommunications, and other demanding applications. The module utilizes advanced switching technology to minimize ripple and noise on the output, ensuring clean and reliable power delivery. The isolated topology eliminates ground loops and improves overall system performance.
