2 / 4 page NX350 3/98 REV B Page 2 Input Specifications Parameter Conditions Min Typ Max Units Operating Range 47-63 Hz 90 264 VAC Inrush Current Limiting 120VAC, cold start 37 APK 240VAC cold start 70 APK Efficiency 120V, full load 70 % 240V, full load 75 % Power Factor Correction (PFC) 0.99 Meets IEC 1000-4-7/EN61000-3-2 (formerly IEC 555-2) 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/Of 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. OverTemperature 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. |
