The NFS40-7628 is a 40W AC/DC converter from Artesyn Embedded Power. It features a wide input voltage range of 85-264 Vac and 120-370 Vdc, with an input frequency range of 47-440 Hz. The converter provides three outputs: +5.1V at 350mA, +12V, and -12V. Total power output is 40W under free air convection, increasing to 50W with 20 CFM forced air.
Typical efficiency is 70%. Line regulation is ±0.2% on the main output and ±1.0% on auxiliary outputs. Load regulation is ±2.0% on the main output and ±5.0% on auxiliary outputs. Hold-up time is 14 ms at 110 Vac and 110 ms at 230 Vac. The converter includes overvoltage protection on the +5V output (S3.15A fuse) and continuous short circuit protection on single outputs, with short-term protection on multiple outputs.
Isolation voltage is 3000 Vac between input and output, and 1500 Vac between input and chassis. The operating temperature range is 0°C to 70°C with derating. The temperature coefficient is ±0.02%/°C on all outputs. Transient response on the +5V output (1.5-3A step) is 500 µs maximum.
The input voltage range is 85-264 Vac and 120-370 Vdc, with a frequency range of 47-440 Hz.
The outputs are +5.1V at 350mA, +12V, and -12V.
The total power is 40W under free air convection and 50W with 20 CFM forced air.
The operating temperature range is 0°C to 70°C with derating.
It includes overvoltage protection on the +5V output (S3.15A fuse) and short circuit protection: continuous on single outputs, short term on multiple outputs.
