FSP090-DBBN3 90W AC-DC Power Supply Adapter

The FSP090-DBBN3 is a high-performance 90-watt AC to DC desktop power supply, designed as a universal AC-DC adapter for a wide range of ITE applications including IPC systems, embedded systems, POS systems, all-in-one computers, Mini-ITX systems, printers, and monitors. As a 19Vdc 4.74A power supply, this adapter features a universal AC input of 90-264Vac at 47-63Hz, ensuring global voltage compatibility. With a maximum input current of ≤1.5A at 100Vac full load, this computer PSU boasts a no-load power consumption of ≤0.15W and a touch current of ≤0.25mA at 264Vac/50Hz. Delivering a stable 19V output at 4.74A with a total output power of 90W, this psu computer adapter includes robust protection features: Over Voltage Protection (OVP), Over Current Protection (OCP) with short circuit protection, and Over Temperature Protection (OTP). It achieves high efficiency ratings of ≥88% (DOE Level VI), ≥89% (ErP Tier 2), and ≥89% (CoC V5 Tier 2), and incorporates a PFC circuit with a power factor of ≥0.9 at full load. Engineered for reliability, this dc power supply offers a hold-up time of ≥10ms at full load, a turn-on time of ≤3.5 seconds, and an MTBF of 300,000 hours at 25°C (SR332 standard). It meets stringent EMC standards including EN55032/EN55024 Class B and FCC Part 15B Class B, and complies with safety standards IEC 62368-1 and IEC 60950-1. The unit is designed with a power de-rating curve for optimal performance across temperatures (100% load at 0°C to 40°C, derated to 55% load at 70°C) and features a withstand voltage of 4242VDC between input and output.
