The NFS40-7908J is a 40W AC/DC converter manufactured by Artesyn Embedded Power, designed for reliable off-board power delivery in demanding environments. It accepts a wide universal input voltage range of 85-264 VAC or 120-370 VDC across frequencies from 47 to 440 Hz. The unit delivers a main output of 5.1V alongside auxiliary outputs of ±12V, maintaining tight line regulation of ±0.2% on the primary rail.
Engineered for robust performance, this converter includes continuous short circuit protection for single outputs and short-term protection for multiple outputs. It also features overvoltage protection set at 6.25 ± 0.75 Vout and an input surge current rating of up to 22 A at 230 VAC. The device maintains low safety ground leakage currents of 18 µA at 110 VAC and 28 µA at 230 VAC.
Thermal management supports operation from 0°C to 70°C with linear derating to 50% load above 50°C. Convection cooling delivers 40W at 50°C ambient, while forced air at 20 CFM supports up to 50W. The unit meets EN55022 and FCC Part 15 Level A emissions standards and withstands ESD levels per EN61000-4-2. It is rated for operation up to 10,000 feet altitude and vibration resistance of 0.75 G peak across 5-500 Hz.
This converter fits applications requiring multi-rail DC power with high reliability, such as industrial control systems, telecommunications equipment, and medical instrumentation where compact off-board power solutions are necessary.
The converter provides a main output of 5.1V and auxiliary outputs of ±12V.
The unit operates continuously from 0°C to 70°C, with linear derating to 50% load above 50°C.
Single outputs feature continuous short circuit protection, while multiple outputs have short-term protection.
The converter withstands up to 10 A surge at 110 VAC and 22 A at 230 VAC during cold start.
Yes, it complies with EN55022 and FCC Part 15 Level A for both conducted and radiated emissions.
