NET1

NET1 SERIES 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 Produc t Release 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.
