The NFS40-7912 is a 40W AC/DC converter from Artesyn Embedded Power designed for single-output applications. It delivers 12V at 40W under free-air convection cooling, with 50W available with 20 CFM forced air. Peak power capability is 60W for 30 seconds. The converter accepts a universal input voltage range of 85-264 VAC (47-440 Hz) or 120-370 VDC.
Key electrical specifications include line regulation of ±0.2% on the main output and ±1.0% on auxiliary outputs, load regulation of ±2.0% and ±5.0% respectively, and a temperature coefficient of ±0.02%/°C on all outputs. Transient response for a 1.5-3A step on the +5V output is ±120 mV maximum deviation with 500 µs recovery. Protection features include overvoltage protection on the +5V output set at 6.25 ± 0.75V, primary power limiting at 90W, and continuous short circuit protection on single outputs (short term on multiple outputs).
The operating temperature range is 0°C to 70°C, with derating linearly to 50% load from 50°C to 70°C ambient. Non-operating temperature range is -40°C to +85°C. Relative humidity tolerance is 5 to 95% non-condensing. Input surge current is 10A typical at 110 Vac and 22A at 230 Vac. Safety ground leakage current is 18 µA max at 110 Vac and 28 µA at 230 Vac.
