NET2 AC-DC Series Data Sheet
Advance Product Release
Features * 400W output power with currents over 100 Amps * 85% efficiency (typical) * 5-output construction * Isolated V2 and V3 outputs * Standby output of 5V @ 2A * Fits 1U chassis height constraints * No minimum load requirement * Active current-share capabilities with redundant capabilities on the four main outputs * Patented high-efficiency design * Meets European power factor requirements * Excellent load transient response * Redundancy without use of ORing diode Description Designed to meet the stringent requirements of today's high-speed circuitry, Power-One's NET2 Series is an excellent compact power solution for low-voltage, high-current applications. The NET2's high efficiency is achieved through the use of synchronous rectification and a newly-patented "Soft Transition Forward Converter". The NET2'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 NET2's height to 1.59" (40.3mm) to fit in 1U applications. NET2'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.

Overvoltage protection on all outputs except V5. Unit latches off when overvoltage is detected. AC input must be recycled to reset. V5 is protected by a 6.2V 5%, 2W Zener diode. Fully protected against output overload and short circuit. Automatic recovery upon removal of overload condition. All outputs are individually current limited. Power supply shuts down due to excessive internal overtemperature at the output converter's primary switching transistors. Power supply resets automatically upon removal of the overtemperature cause. TTL-compatible global Output Good signal. The signal is active when any of the V1-V4 outputs drop >14% below nominal. Source impedance is 1k . Open collector signal. Time before regulation dropout due to loss of input power. May be used as independent PSOK signal in redundant applications. Available on all outputs except V5. Accuracy of shared current with up to two parallel units. Single wire current share is provided. For paralleling more than two units, consult factory. Available on all outputs except V5. Total voltage compensation for cable losses with respect to the main output.
