FSP090-AAAN3 90W 24V AC-DC Power Adapter with DoE Level VI & CoC V5 Tier 2 Efficiency

The FSP090-AAAN3 is a 90-watt AC to DC power adapter from the FSP090-AxxN3 Series, designed to deliver reliable and efficient power for IPC systems, embedded systems, printers, monitors, POS systems, and PoE applications requiring medium power. This 24V power supply accepts a universal input of 90-264VAC (47-63Hz) and provides a regulated 24VDC output at 3.75A (90W total). It meets stringent energy efficiency regulations including DoE Level VI and CoC Version 5 Tier 2, achieving ≥88% (DoE) and ≥89% (CoC) efficiency. The adapter is fully protected with Over Voltage Protection (OVP, trip at 60V typical), Over Current Protection (auto-recovery), Over Temperature Protection (auto-recovery), and incorporates a Power Factor Correction (PFC) circuit to maintain PF ≥0.9 at full load. It complies with IEC 62368-1 and CB 60950-1 safety standards, and its EMC performance meets CISPR32/EN55032 Class B, FCC Part 15B Class B, and various immunity standards (EN61000-4-2/4/5/6/8/11). The unit features a low-profile design, high reliability with 300,000 hours MTBF (SR332 at 25°C), and operates over a wide temperature range of 0-70°C with proper derating above 40°C (85% load at 50°C, 70% at 60°C, 55% at 70°C). Additional specifications include ≤1.2A input current, <0.5W no‑load power consumption, ≥10ms hold‑up time at full load, ≤3s power‑on time, and 5000m operating altitude. With its comprehensive protection features and global safety certifications, the FSP090-AAAN3 is an ideal choice for industrial and ITE equipment requiring a compact, high‑efficiency 24V power solution.
