QS4A_1205S1.5UP – GAPTEC

The QS4A_1205S1.5UP is a galvanically isolated DC-DC converter module engineered for point-of-load power delivery. This module provides a tightly regulated 5V output at 50mA, delivering 0.25W. The input voltage range is specified as 10.8V to 13.2V, offering a ±10% tolerance around a nominal 12V input. Isolation is implemented to enhance system safety and reduce ground loop issues. Efficiency is rated at 75%, minimizing heat dissipation. The converter utilizes a robust design, enabling operation across a wide temperature range of -40°C to +105°C, suitable for harsh industrial environments. The module’s compact form factor facilitates easy integration into space-constrained applications. Internal filtering minimizes EMI, and protection circuitry includes short-circuit and over-temperature protection, ensuring reliable operation and preventing damage to the module and connected loads.
