Advanced Energy / Artesyn NFS40-7608 Power Supply Board

The Advanced Energy/Artesyn NFS40-7608 is a 40W open-frame AC-DC power supply board engineered for industrial, communications, networking, and computer peripheral applications. This compact unit delivers three regulated output voltages - +5.1V, +12V, and -12V - from a universal input range of 85 VAC to 264 VAC or 120 to 370 VDC. Measuring just 5.00" × 3.00" × 1.20" with a 0.26 lbs footprint, it fits 1U form-factor requirements while maintaining convection or forced-air cooling flexibility.
