Description
Designed to meet the stringent requirements of today鈥檚 high-speed circuitry, Power-One鈥檚 NET2 Series is an excellent
compact power solution for low-voltage, high-current applications. The NET2鈥檚 high efficiency is achieved through the
use of synchronous rectification and a newly-patented 鈥淪oft Transition Forward Converter鈥?
The NET2鈥檚 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鈥檚 height to 1.59鈥?(40.3mm) to fit in 1U
applications. NET2鈥檚 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鈥?quick disconnects, cable connectors, and PCB-mounted connectors.
