The NLP40 series is a 40 W universal input ac-dc power supply on a 4.25 x 2.5 inch card
with a maximum component height of 1.15 inches for use in 1U applications. This product is
the smallest standard 40 W package in the industry making the series ideal for
communication applications with space constraints where a standard 5 x 3 inch card
solution is not suitable. The NLP40 provides 40 W of output power with free air convection
cooling which can be boosted to 50 W with 20 CFM of air. Standard features include
overvoltage and short circuit protection. The series, with full international safety approval and
the CE mark, meets conducted noise EN55022 level B and has immunity compliance to
EN61000-4-2,-3,-4, -5, -6. The NLP40 series is designed for use in low power data
networking, computer and telecom applications such as hubs, routers, POS terminals, LCD
projectors, cable modems and PABX’s. This list is not exclusive as the generic feature set of
the NLP40 series with industry standard output configurations provides a solution for most
low power applications including many industrial applications.
