The Artesyn NFS40-76S3J is a single-output AC-DC converter delivering 40W of continuous power with a 3.3V output. It accepts a universal input range of 85-264 Vac or 120-370 Vdc, making it suitable for global applications. The converter achieves 70% typical efficiency and operates over a 0°C to 70°C temperature range with derating above 50°C.
Electrical features include line regulation of ±0.2% on the main output, load regulation of ±2.0%, and transient response recovery within 500 µs. Protection features include overvoltage protection on the +5V output, continuous short circuit protection on single outputs, and an input power limit of 90W. The unit provides 3000 Vac input-to-output isolation and 1500 Vac input-to-chassis isolation.
The converter is designed for convection cooling delivering 40W at 50°C ambient, or 50W with 20 CFM forced air. It complies with EN55022 and FCC Part 15 Level B for conducted emissions and meets safety standards including VDE0805, EN60950, IEC950, UL1950, and CSA C22.2 No. 950.
The input voltage range is 85-264 Vac or 120-370 Vdc.
The output is 3.3V with a total power of 40W in free air convection or 50W with 20 CFM forced air.
The operating temperature range is 0°C to 70°C with derating above 50°C.
It is approved to VDE0805, EN60950, IEC950, IEC1010, UL1950, and CSA C22.2 No. 950.
The typical efficiency is 70%.
