AKM90PS19

The AKM90PS19 is a high-efficiency AC/DC desktop power adapter manufactured by XP Power. Designed for reliable off-board power delivery, this unit provides a nominal 19V output capable of sourcing up to 4.76A, resulting in a total power rating of 90W. The adapter accepts a universal input voltage range of 90 to 264 VAC across 47 to 63 Hz, making it suitable for global deployment without manual reconfiguration.

Engineered for performance and safety, the unit achieves typical efficiencies between 89% and 90.7% depending on line voltage. Electrical stability is maintained through a total regulation of 5% and a transient response deviation of 4% under a 60% step load change. Output ripple and noise are tightly controlled at 240 mV peak-to-peak when measured with a 20 MHz bandwidth.

Safety and reliability are prioritized with 4000 VAC reinforced isolation rated for two times Mean Operational Path Protection (2 x MOPP). The adapter incorporates continuous short circuit protection utilizing a hiccup mode with automatic recovery, alongside overload protection spanning 125% to 170% of rated capacity. Additional electrical characteristics include a maximum inrush current of 100 A at 230 VAC cold start and a hold-up time of 10 ms at full load and 100 VAC input.
