NLP40 Series

Single, dual and triple output

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.

All specifications are typical at nominal input, full load at 25 °C unless otherwise stated
