Advanced Energy / Artesyn NFN40-7608 Power Supply Board

The Advanced Energy/Artesyn NFN40-7608 is a 40-watt open-frame AC-DC power supply board engineered for integration into distributed electronic systems. Operating across universal input voltage (85–264 VAC, 120–370 VDC) at 47–63 Hz, it eliminates regional supply constraints for global deployment. This triple-output converter delivers +5.1V, +12.0V, and -12.0V rails with load regulation down to zero load, meeting EN55022 Class B and FCC Part 15 Class B emissions standards.

Fixed-frequency operation minimizes conducted noise, while overvoltage and short-circuit protection safeguard downstream circuitry.
