NOTES: 1) V1 + V2, or V3 + V4 must not exceed 200W.

2) Maximum peak-to-peak noise for a 20 MHz bandwidth.

3) Initial set points: V1 @ 40A, V2 @ 4A, V3 @ 4A, V4 @ 30A, and V5 @ 1A.

4) Consult factory for availability.

Designed to meet the stringent requirements of today’s high-speed circuitry, Power-One’s NET2 Series is an excellent

compact power solution for low-voltage, high-current applications. The NET2’s high efficiency is achieved through the

use of synchronous rectification and a newly-patented “Soft Transition Forward Converter”.

The NET2’s rectification method lowers output losses, reduces system cooling requirements (allowing greater power

in a smaller package), and eliminates minimum-load requirements.

Advanced surface-mount design and packing technology reduce the NET2’s height to 1.59” (40.3mm) to fit in 1U

applications. NET2’s high-performance active power factor circuitry meets EN61000-3-2 requirements for compliance

with European Power Line Harmonic Requirements for 2001. A multifunctional output terminal allows connection to #8

ring lugs, 0.25” quick disconnects, cable connectors, and PCB-mounted connectors.
