NLP25 Series

Single, dual and triple output

The NLP25 series is a 25W 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 25W of output power with free air convection

cooling which can peak at 30W 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 5V 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
