HIGHLY COMPACT 225W AC/DC POWER SUPPLY FOR MEDICAL AND ITE APPLICATIONS

Jan. 17, 2008
Power Sources Unlimited announces the NXT-225 Series of ultra small , (3” x 5” x 1.5”) ac/dc power supplies which pack 225W of power into an industry leading 10W/inch3 power density, fitting easily into 1U high OEM applications or any application where space is critical. The NXT-225 Series features a power factor corrected, universal 90-264VAC input.   Eight models provide adjustable, single outputs from 2.5VDC to 48VDC, with isolated 5VDC standby power available as an option. Efficiency is 85% typical, line and load regulation are 0.5%, and operating temperatures are up to +70ºC with airflow.  Comprehensive protection circuitry is inherent in the NXT-225 design.  Available options are remote inhibit/enable, cover and chassis, and single wire load sharing,   Load sharing evaluation boards are also available. Worldwide safety compliance to both EN60101-1 (Medical) and EN60950-1 (Information Technology Equipment) standards, RoHS compliance, a 2-year warranty and a high MTBF make the NXT-225 Series ideal for numerous applications. • Total Output Power at 150w - Convection Cooled, Open 225W 50C • 300 LFM Forced Air,Open Frame • Power Derating - 1.5 W1Vbelow 100 V out / in in • Voltage Centering - +/-0.5% (50% Load) • Voltage Adjust Range - 95-105% • Load Regulation - 0.5% (0-100% load change) • Source Regulation - 0.5% • Noise - 1.0% 100mV or Whichever is greater • Transient Response - Output recovers to within 1% of initial set point due to a 50% step load change, 500uS maximum, 4% maximum deviation. • Turn on Overshoot - None • Overvoltage Protection - Latching, between 110% and 150% of rated output voltage. • Overpower Protection - 110-130% rated Pout, cycle on/off, auto recovery • Hold Up Time - 16 mS min., Full Power, 85-264V Input • Start Up Time - 3 Seconds, 120V Input
