NX301-U3A

Product Data Sheet 300 WATT AC/DC POWER SUPPLY NX301 DESCRIPTION The NX301 is a compact 300 watt Power Factor Corrected, multiple output power supply. All outputs are fully isolated and regulated. Active current sharing circuitry, together with control functions and alarm options, simplifies N+1 and redundant applications. Fan and disk drive applications are handled by the peak current ratings of the auxiliary outputs. FEATURES Active Power Factor Correction Fully Isolated Outputs Low Profile: 9” x 4.85” x 2.00” One, Two, Three and Four Output Models N+1 Current Sharing FCC/VDE Class B EMI Filter Standard Optional Fan Mounted On Cover AGENCY APPROVALS 3400 E Britannia Drive NX301 3/98 REV B Tucson, Arizona 85706 Phone: 520.295.4100 Fax: 520.770.9369 Internet: http://www.cdpowerelectronics.com Page 1 Input Specifications Parameter Operating Range Inrush Current Limiting 120VAC, cold start 240VAC, cold start Efficiency 120V 240V Power Factor Correction (PFC) Meets IEC 1000-4-7/EN61000-3-2 (formerly IEC 555-2) 120V, full load 240V, full load 70 75 0.99 % 35 70 APK APK Conditions 47-63 Hz Min 90 Typ Max 264 Units VAC % Remote Sense Remote Sense is provided on Output #1 and will compensate for 0.7V of line drop. Remote Sense leads are protected against open, short and reversal. Remote On/Off The power supply is turned on with a TTL logic ‘1’ (or open) signal and turned off by a switch closure or TTL logic ‘0’ referenced to (-) sense terminal. Consult the factory for other options. Over Voltage Protection Output #1: 6.5V ± 0.5 VDC. The power supply will latch off until AC power is cycled. Over Current Protection Individual current limit on all outputs. Automatic recovery upon fault removal. Transient Response The peak output voltage excursion will not exceed 2% and will recover within 1% in 200 µsec for a 25% load step change. Output Isolation All outputs are fully isolated. Power Fail Signal Upon AC input voltage removal, the power fail signal drops to logic zero at least 5msec before loss of DC output. On AC input turn-on, signal remains low until outputs are in regulation. Consult the factory for other options. N + 1 Load Share Output #1 has active load sharing circuitry. Units will load share within 1.5% of Maximum Rated Load. Over Temperature Protection Thermal switch turns off power supply if overheating occurs and automatically restarts. Safety UL Recognized: UL File Number E14675 (1950 & 1012) CSA Certified: CSA File Number LR 9070-154C (C22.2 No. 234-M90, Level 6) TUV License Number: R9576031 (EN60950) (IEC950) Cooling The unit is designed to operate with 30 CFM of airflow.
