FSP045-RECN2 45W 19V 2.37A AC-DC Power Adapter for ITE & Notebooks

The FSP045-RECN2 is a reliable 45W external AC-DC power supply designed for notebooks, ITE equipment, and small electronic devices requiring a stable 19V DC input. This universal adapter operates over a wide input voltage range of 90Vac to 264Vac (47-63Hz) and delivers a regulated 19Vdc output at up to 2.37A, with a total output power of 45W. It meets Energy Star 2.0 Level V efficiency standards, achieving an average efficiency of ≥87.5% at 115Vac/230Vac (tested at 25%, 50%, 75%, and 100% load). The unit features comprehensive protections including over voltage protection (latch-off, 28.5V max), over current protection (auto-recovery, ≤5.0A), short circuit protection (auto-recovery), and over temperature protection (latch-off). With a compact footprint (89.8 x 37.8 x 27.5mm) and natural convection cooling, it is ideal for space-constrained applications. EMC compliance includes EN55022/CISPR22 Class B and FCC Part 15 Class B with 6dB margin, and it is certified to IEC60950 for safety.
