NAL40 Series

Single, dual and triple output

The NAL40 series are 40W universal input AC/DC power supplies on a 5 x 3 inch card

with a maximum component height of 1.2 inch for use in 1U applications. These series

are available with a wide range of models in the industry standard 5 x 3 inch footprint

at low cost making the series ideal for new and existing high volume communication

and industrial applications. The NAL40 meets level A conducted emissions. The NAL40

series provide 40W of output power with free air convection cooling with a peak output

of 50W for a maximum duration of 60 seconds. The NAL40 series are designed for use

in high volume low power data networking, computer and telecom applications such as

hubs, routers, POS terminals, cable modems and PABX’s. This list is not exclusive as

the generic feature set of both series with industry standard output configurations

provide a solution for most high volume applications including many industrial

applications.

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