NLP25 Series

Single, dual and triple output

The NLP25 series is a 25 W universal input ac-dc power supply on a 4.00 x 2.07

inch card with a profile of less than 1 inch. The availability of four single output and

three multiple output models in an extremely small package size make the NLP25

ideal for use in space critical, low power communication applications requiring an

off line power solution. The NLP25 provides 25 W of output power with free air

convection cooling which can peak at 30 W for 60 seconds. Standard features

include overvoltage and short circuit protection. The series, with full international

safety approvals and the CE mark, meets conducted emissions EN55022 level B

and complies to EN61000-4-2,-3,-4, -5 and -6 immunity standards. The NLP25

series is designed for use in off line, low power data networking and computer

applications with limited space, such as hubs, routers, POS terminals, external disk

storage and cable modems. The availability of 5 V outputs in single and multiple

configurations provides a solution for a myriad of microprocessor applications.

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