NLP40 Series

Single, dual and triple output

The NLP40 series is a 40W 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 40W 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 40W of output power with free air convection

cooling which can be boosted to 50W with 20CFM 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
