NLP150L Series

Single and triple outputs

EN61000-4-2, -3, -4, -5 and -6

The NLP150L series of 150 Watt AC/DC open frame power supplies are available with

single, triple or quad outputs. The single and triple output versions described in this

datasheet are housed in a 3.8 x 6.8 x 1.26 inch package. All NLP150L series power

supplies are harmonic current corrected to meet the EN61000-3-2 standard, and support

current sharing. The power supplies are designed for use in 1U shelves or boxes, and are

primarily intended for networking applications that have a heavy logic content, such as

access concentrators, midrange routers, LAN switches and shared media hubs.

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