QT8E_1503S1U – GAPTEC

The QT8E_1503S1U is a compact, isolated DC-DC converter module designed for embedded applications requiring a regulated 3.3V output. It delivers a stable 76mA output current from a nominal 15V input, accommodating a wide input voltage range of 13.5V to 16.5V (±10% tolerance). This module incorporates galvanic isolation to provide electrical separation between the input and output stages, enhancing system safety and reducing ground loop noise. With a typical efficiency of 73%, the QT8E_1503S1U minimizes power dissipation and operates reliably across a broad temperature range of -40°C to +85°C, making it suitable for harsh industrial environments. The 0.25W power rating ensures efficient operation in low-power applications. Internal protection circuitry includes overload and short-circuit protection, ensuring robust performance and longevity. This module is ideal for applications requiring a stable and isolated 3.3V supply from a 15V source.
