| 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. 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 MULTIPLE OUTPUT MODEL SELECTION CHART - 240W WITH 300 LFM FORCED AIR COOLING MODEL OUTPUT VOLTAGE ADJUSTMENT RANGE OUTPUT CURRENT (NOTE 1) LINE REGULATION LOAD REGULATION RIPPLE & NOISE %Pk-Pk (NOTE 2) INITIAL SETTING ACCURACY NET1-4325 NET1-4130 NET1-4112 +3.3V +2.5V +5V +12V +1.8V +3.3V +5V +12V +1.8V +1.65V +5V +12V +0.5V +0.5V FIXED FIXED +0.5V +0.5V FIXED FIXED +0.5V +0.5V FIXED FIXED 50A 50A 5A 4A 50A 50A 5A 4A 50A 50A 5A 4A 0.2% 0.2% 0.2% 0.2% 0.2% 0.2% 0.2% 0.2% 0.2% 0.2% 0.2% 0.2% 1% 1% 3% 3% 1% 1% 3% 3% 1% 1% 3% 3% 1% or 50mV 1% or 50mV 1% or 50mV 1% or 50mV 1% or 50mV 1% or 50mV 1% or 50mV 1% or 50mV 1% or 50mV 1% or 50mV 1% or 50mV 1% or 50mV 30mV 30mV 30mV 100mV 20mV 30mV 30mV 100mV 20mV 30mV 30mV 100mV NOTES: 1) Output currents ratings are expressed with 300 LFM forced air. 2) Maximum peak-to-peak noise expressed as a percentage of output voltage, 20 MHz bandwidth.
