The Advanced Energy / Artesyn NFS40-7612 is a 40W open-frame AC-DC power supply engineered for industrial and commercial ITE applications. This single-output converter delivers +12V at 3.3A with universal input acceptance from 85–264 VAC or 120–370 VDC, making it suitable for diverse global power environments. The compact 5.00″ × 3.00″ × 1.20″ chassis-mount design fits 1U form factors while maintaining 70% typical efficiency and supports both free-air and forced-air cooling scenarios.
