NLP70 Series

T riple output

The NLP70-9693J is a 70 W (with forced air) universal input ac-dc power supply on a 5.5

x 3 inch card with a maximum component height of 1.26 inches for use in 1U

applications. The model has input harmonic current correction making the series ideal for

product designs that need to comply with EN61000-3-2 legislation. The NLP70 provides

52.5 W of output power with free air convection cooling which can be boosted to 70 W

with 20 CFM of air. The NLP70, 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 NLP70 series is designed for use in low power data networking,

computer and telecom applications using 3.3 V or 5 V logic. The NLP70 can provide the

same current on either the 3.3 V or 5 V channel making it ideal for applications using a

mixture of 3.3V and 5V logic or for applications in transition from 5 V to 3.3 V logic.

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