DESCRIPTION

CENB1090A4803F01 is a universal input 90-watt switch-mode power supply designed for ITE (Information Technology Equipment) applications. It features a 48V single output with a maximum current rating of 1.9A and 90W maximum power output, with output ripple and noise of 240mV peak-to-peak maximum. The unit accepts 100-240VAC input (±10%, 47-63 Hz) with an inrush current of 60A peak at 264Vac, and includes a 3.15A internal primary fuse. The power supply employs a fixed-frequency flyback topology and meets international efficiency standards (EISA2007, CEC Efficiency Level V, EU (EC) No 278/2009 Phase II), with line regulation of ±1% and load regulation of ±5%. It operates over a temperature range of 0°C to 40°C with no derating, features an impact-resistant polycarbonate enclosure (129 × 77 × 40mm), and includes comprehensive safety certifications (UL/EN/IEC60950-1, 2nd Edition) with a 3-year warranty. This regulated power supply is ideal for industrial and commercial equipment requiring reliable, efficient DC power conversion with low no-load consumption (<0.5W) and extended MTBF (>100,000 hours calculated).
