FEATURES
• Currents Over 100 Amps
• Fits 1U Chassis Height Constraints
• No Minimum Load Requirement
• Current Share Capabilities on All Outputs
• Patented High-Efficiency Design
• Meets European Power Factor Requirements for 2001
• Excellent Load Transient Response
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.
