NMX-750, Power Factor Corrected Multiple Output, Forced Current Sharing

FEATURES:
• Forced current sharing for N +1 redundancy
• Remote sense on outputs #1 and 2
• Universal ac input
• typical power factor
• Dual converter design eliminates interaction between
logic and auxiliary outputs
• Low ripple and noise on all outputs
• Dc power good and ac power fail signals
• True remote inhibit
• Monotonic turn-on and turn-off

SPECIFICATIONS:

INPUT Ac Input 90-264 Vac continuous range, 47 to 63 Hz. Internally fused for 15 A. Power Factor typical at full load. Meets EN61000-3-2 Class A. Inrush Cold start ac current is less than 65 A at 115 Vac and 130 A at 230 Vac. Limited by thermistor. Brownout Protection Holds regulation to 85 Vac. Holdup Time 20 ms minimum after removal of power at full load. Efficiency 75% typical. Ac Power Fail Provides TTL “0” 5 ms before output voltage goes out of regulation band upon loss of ac power. OUTPUT Adjustability Outputs #1 and 2 user adjustable ±5% minimum. Output #3 tracks #2 initial accuracy Output #4 user adjustable ±5% minimum, or +5% only if voltage is V. Line & Load Reg Outputs #1, 2, and 4 hold ±1% over ac input range and 0 to 100% load change. Output #3 requires 20% minimum load on outputs #2 and 3 to hold Ripple & Noise Less than 1% p-p or 100 mV, whichever is greater. Remote Sense Outputs #1 and 2 Compensates for 250 mV total line drop. Open sense lead protection. See Redundancy. Temperature Coefficient Outputs #1, 2, and 4 per degree C. Stability over 8 hours after 30 minutes warm-up. Transient Response Outputs #1, 2, and 4 Output voltage returns to within 1% in less than 500 µs for a 50% load change. Peak transient does not exceed Overload Protection All outputs are protected against overload and short circuit. Automatic recovery upon removal of fault. Overvoltage Protection Outputs #1 and 2 Protects load against power supply induced over voltage. Trip point is factory set so that output voltage cannot exceed 136% of nominal. Peak Output Current Dual current ratings define continuous and peak currents. The peak current shown can be delivered for a maximum period of 30 seconds. Remote Inhibit Contact closure to the negative sense line or a TTL level “0” turns off dc outputs. Dc Power Good Provides a TTL “1” when output #1 is above V nominal.

OPTIONS Option “B”, Barrier Strip Provides auxiliary output connections on #6-32 terminal screws with 3/8” centers.
