ASA01F36-LS is a 6-watt isolated DC-DC converter from the Artesyn ASA series designed for high-input applications with an ultra-wide 4:1 input voltage range of 18–75 Vdc, primarily for nominal 48 V supplies. The converter delivers a single 3.3 V output at 1.2 A (3.96 W maximum power) with ±2.0% voltage tolerance and ±0.5% line regulation, achieving 81% efficiency at 5 V nominal input. The unit is fully encapsulated in a compact 1.25 × 0.8 inch (31.7 × 20.3 mm) metal case with a height of 0.4 inch (10.2 mm), providing 1500 Vdc I/O isolation and meeting Mil-STD-202G vibration standards. It operates reliably across -40°C to +71°C with no derating, making it ideal for ruggedized applications in harsh environments such as telecommunications, industrial, and aerospace systems.
