Description
Designed to meet the stringent requirements of today’s high-speed datacom and telecom circuitry, Power-One’s NET1
Series is an excellent compact power solution for low-voltage, high-current applications. The NET1’s high efficiency is
achieved through the use of synchronous rectification and a newly-patented “Soft Transition Forward Converter”.
The NET1’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 NET1’s height to 1.35” (34.3mm) to fit in 1U
applications. NET1’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.
