The Artesyn NFN40-7608 is a 40W AC-DC power supply engineered for industrial, commercial, and networking applications requiring compact, reliable multi-output regulation. This open-frame unit delivers 40W under natural convection cooling and scales to 50W with 20 CFM forced air, making it suitable for 1U form-factor integration. It accepts universal input from 85-264 VAC at frequencies up to 440 Hz and provides three isolated DC outputs: +5.1V at 3A, +12V at 2A, and -12V at 350mA, with peak currents of 7A, 3A, and 1A respectively. The supply maintains output regulation of ±2.0% on the +5.1V rail and ±5.0% on the ±12V rails, with ripple and noise limited to 50mV and 120mV respectively. Built-in overvoltage and short-circuit protection safeguard downstream circuitry. At 70% efficiency with a 280g footprint of 127 × 76.2 × 30.48 mm, the NFN40-7608 integrates into space-constrained designs. Leakage current measures 0.13mA at 110 VAC (60 Hz) and 0.32mA at 230 VAC (50 Hz). The unit operates across 0°C to +70°C and sustains operation at altitudes up to 10,000 feet. A minimum 4W load is required to achieve design MTBF specifications. Isolation voltage is rated at 3 kVAC. Emissions comply with EN55022 Level A and FCC Part 15. RoHS-compliant versions are available. International safety approvals and CE marking are standard.
