QS4E_1507S1U – GAPTEC

The QS4E_1507S1U is a single-output, isolated DC-DC converter module designed for applications requiring galvanic isolation and tightly regulated output. This module delivers a stable 7.2V DC output at 34.7mA, providing 0.25W of power. It accepts a wide input voltage range of 13.5V to 16.5V, accommodating fluctuations of ±10% around a nominal 15V input. The converter utilizes a fixed-frequency switching topology to achieve a typical efficiency of 74% across the input voltage range. Robust thermal management allows for operation across a wide temperature range of -40°C to +85°C, making it suitable for harsh environments. Isolation is achieved through a transformer-based design, providing a high degree of electrical separation between input and output. Internal filtering minimizes EMI and RFI emissions.
