FSP120-AAAN3 120W 24V 5A AC-DC Power Supply Adapter

The FSP120-AAAN3 is a 120-watt AC-DC power adapter from the FSP120-AxxN3 series, designed to deliver reliable and efficient power for industrial and commercial applications such as IPC systems, embedded systems, printers, monitors, POS systems, and PoE equipment. It accepts a universal input voltage of 90-264VAC (47-63Hz) with a maximum input current of ≤1.2A at 100Vac/240Vac full load, no-load power consumption ≤0.5W, and touch current ≤0.25mA at 264Vac/50Hz. The adapter provides a regulated 24VDC output at 5A, total power 120W, with over voltage protection set at 63V. Built-in protections include over current, short circuit, over temperature, and brown-out, ensuring safe operation under abnormal conditions. Efficiency meets ≥88% (DOE Level VI) and ≥89% (CoC V5 Tier 2) with power factor ≥0.9 at 115Vac/230Vac full load, complying with EN61000-3-2 harmonic requirements. Hold-up time is ≤10ms at 100Vac or 240Vac full load, and turn-on time ≤3 seconds at 100Vac full load. The adapter features high reliability with MTBF 300,000 hours at 25°C (SR332) and isolation voltage 4242VDC between input and output, with altitude capability up to 5000m. EMC performance meets Class B standards: CISPR32 EN55032 Class B, EN55024, FCC Part 15B Class B; immunity includes ESD ±15kV air/±8kV contact (criterion A), radiated RF 3V/m, EFT ±1kV, surge ±1kV diff/±2kV common mode, conducted RF 3Vrms, power frequency magnetic field 1A/m, and voltage dips/interruptions per criterion B/C. Operating temperature range is 0°C to 40°C (100% load), derated to 85% load at 50°C, 70% at 60°C, and 55% at 70°C. The adapter is certified to IEC 62368-1 & CB 60950-1, meets USA EISA 2007, features a built-in PFC circuit, and uses a C14 AC inlet. It is an ideal power solution for medium-to-high power 24V equipment.
