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.
