NLP65-3300J

Single output

The NLP65-3300J is a 33 W universal input ac-dc power supply on a 5 x 3 inch card with a

maximum component height of 1.26 inches for use in 1U applications. This model has the

option of input harmonic current correction in the same package size making the series ideal

for product designs that will need to comply with EN61000-3-2 legislation. The NLP65-3300J

provides 33 W of output power with free air convection cooling. The NLP65, with full

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

and has immunity compliance to EN61000-4-2, -3, -4, -5, -6. The series is available in a

factory installed enclosure with an IEC connector and output connector on flying leads plus a

cover kit for self-installation is also available as an accessory. The NLP65 series is designed

for use in low power data networking, computer and telecom applications such as hubs,

routers, POS terminals, internet servers, cable modems and PABX’s. This list is not exclusive

as the generic feature set of the NLP65 series with industry standard output configurations

provides a solution for most low power applications including many industrial applications.

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