NLP25 Series
Single, dual and triple output
• 4.00 x 2.07 x 0.91 inch package
• Overvoltage protection and short circuit protection
• 25 W with free air convection cooling
• EN55022, EN55011 conducted emissions level B
• UL, VDE, CSA and CCC safety approvals
• Available RoHS compliant
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
