The NAL25 series are 25W universal input AC/DC power supplies on a 5 x 3 inch
card with a maximum component height of 1.2 inches for use in 1U applications.
This series is available in an 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 NAL25 series meets level A conducted emissions. The
NAL25 series provide 25W of output power with free air convection cooling with a
peak of 30W for a maximum of 60 seconds. The NAL25 series are designed for use
in high volume low power data networking, computer and telecom applications such
as hubs, POS terminals, modems and small 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
