VAWQ3-Q48-S5H is an isolated DC-DC converter designed to convert a wide input voltage range of 18–72V to a regulated 5V single output. The module delivers up to 3W of isolated power with a maximum output current of 600mA and achieves typical efficiency of 72%. It features 3,000V DC isolation, short circuit protection, and operates reliably across a wide temperature range of -25°C to +95°C with derating. The industry-standard 24-pin DIP package, combined with low ripple and noise (100mVp-p maximum), makes this converter suitable for industrial control systems, telecommunications equipment, and other applications requiring galvanic isolation and stable power delivery in harsh environments.
