3TAW_4812D1.5 – GAPTEC

The 3TAW_4812D1.5 is a compact, fully isolated DC-DC converter module designed for distributed power architectures and demanding industrial applications. This unit delivers dual 12V outputs, each capable of sourcing 125mA, providing a total power output of 3W. The wide 2:1 input voltage range, spanning 36V to 75V, accommodates fluctuations in typical 48V nominal bus voltages. A robust design ensures reliable operation across a wide temperature range of -40°C to +85°C, making it suitable for harsh environments. The module achieves a typical efficiency of 81%, minimizing heat dissipation and maximizing power delivery. Isolation is a key feature, providing galvanic isolation between the input and output stages, enhancing system safety and reducing ground loop issues. The fixed switching frequency and internal filtering contribute to low output noise and ripple. This converter is ideal for applications requiring isolated power rails and high reliability in a small form factor.
