NLP40 Series Single, dual and triple output • 4.25 x 2.5 x 1.15 inch package (1U applications) • Smallest industry package • Overvoltage and short circuit protection • 40 W with free air convection • EN55022, EN55011 conducted emission level B • EN61000-4-2, -3, -4, -5, -6 immunity compliant • UL, VDE and CSA safety approvals • Available RoHS compliant 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.
