NAN55 SERIES
Single, dual and triple output
• 5.0 x 3.0 x 1.2 inch package (1U applications)
• Industry standard package
• Overvoltage and short circuit protection
• 45W with free air convection
• 55 Watts with 5CFM
• EN55022, EN55011 conducted emissions level B
• UL, VDE and CSA safety approvals
The NAN55 series is a 55W universal input AC/DC power supply on a 5 x 3 inch
card with a maximum component height of 1.2 inches for use in 1U
applications. The NAN55 series is available in four standard models, in the
traditional 40W standard footprint, but with increased load capability on the
main 5V output. This ensures suitability for logic and processor applications that
have larger load requirements than existing 40W designs due to increased
functionality. The NAN55 provides 45W of output power with free air convection
cooling which can be boosted to 55W with 5CFM of air. Standard features
include overvoltage and short circuit protection. The series, with full international
safety approval and the CE mark, meets conducted emissions EN55022 level B.
The NAN55 series is designed for use in low power data networking and
computer applications such as hubs, routers, POS terminals, internet servers
and cable modems.
