FSP090-ASC 90W 19V AC-DC Power Adapter

The FSP090-ASC is a high-performance 90W AC-DC power adapter designed to deliver stable and reliable 19V DC output for a wide range of applications, including laptops, IPC systems, office equipment, and medium-power electronic devices. Engineered with a universal input range of 90-264Vac (47-63Hz), this adapter ensures global compatibility and consistent performance under varying grid conditions. It achieves ≥85% efficiency at full load (100/240Vac) and features ultra-low no-load power consumption ≤1W, meeting modern energy-saving standards. The output voltage is precisely regulated between 18.05V and 19.95V, with ripple and noise limited to ≤300mVp-p (tested with 0.1µF ceramic and 47µF aluminum capacitors in parallel, 20MHz bandwidth). Dynamic load changes (±50% of half load) keep the output within specification. Protection features include auto-recovery short circuit and over current (max 8A), plus latch-mode over temperature protection (AC reset ≤2 minutes). The adapter complies with IEC1000-4-2/4/4-5 Level 3 for ESD, fast transients, and surge immunity, and meets EMI standards FCC Part 15J Class B, EN55022 Class B, and VCCI Class II. Safety certifications include UL, c-UL, VDE, and NEMKO+CB, with leakage current ≤250µA (240Vac) and dielectric strength of 3kV AC input to secondary. Housed in a compact black case (145×62×33.5mm) weighing 450g, it features an IEC 320 C8 AC inlet with I/O switch and a 1500±50mm black DC output cable. Designed for natural air cooling, it operates in 0–35°C ambient temperatures.
