NET1 SERIES
Designed to meet the stringent requirements of today鈥檚 high-speed
datacom and telecom circuitry, Power-One鈥檚 NET1 series is an excellent
compact power solution for low-voltage, high-current applications. The
NET1鈥檚 high efficiency is achieved through the use of synchronous
rectification and a newly-patented 鈥淪oft Transition Forward Converter鈥?
The NET1鈥檚 rectification method lowers output losses, reduces system
cooling requirements (allowing greater power in a smaller package), and
eliminates minimum load requirements.
Advanced Produc
t
Release
Advanced surface-mount design and packing technology reduce the
NET1鈥檚 height to 1.35鈥?(34.3mm) to fit in 1U applications. NET1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.
