The smallest, most capable 750 W
power supply of its kind.
Condor has developed the NMX Series
of power supplies to meet the global market’s demand for increased performance
and reliability. In the NMX, universal input,
smaller volume and added features have
been achieved without compromising
Condor’s superior reliability. Condor
engineers have perfected a unique
converter that operates up to 350 kHz,
with increased efficiency. This allows us

to make smaller power supplies without
the penalty of higher operating temperatures.
Refined use of surface mount technology
allows Condor to add performance features
such as forced current sharing and power
factor correction. It also assures enhanced
reliability through the reduction of circuit
board area and the number of through-hole
components.

SPECIFICATIONS: ALL MODELS
INPUT
AC Input: 90-264 Vac continuous range, 47 to 63 Hz. Internally fused for 15 A.
Power Factor: 0.99 typical at full load. Meets EN61000-3-2.
Inrush: Cold start AC current is less than 50 A at 115 Vac and 100 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 ±4%. Output #4 user adjustable ±5% minimum, or +5% only if voltage is 5.2 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 ±4%.
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, below.)
Temperature Coefficient (Outputs #1, 2, and 4): 0.02% per degree C.
Stability: 0.1% 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 5%.
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 4.6 V nominal.
Redundancy: External OR-ing diodes and forced current sharing on output #1 provide “N+1”
capability. Remote Sense (+S) compensates for additional 0.6 V diode voltage drop. When
the current sharing terminal is connected between units, current sharing remains within
10% of the unit’s full output current rating.
ENVIRONMENTAL
Thermal Protection: Shuts down power supply if overheated. Automatic recovery.
Temperature Range: 0° to 50° C at full ratings.
Safety Agencies: Most models are approved to UL1950; CSA 22.2 #234; IEC 950 and TÜV
EN60950, Class 1 SELV., CE 72/23/EEC/93/68EEC (low voltage directive)..
Conducted RFI: Meets FCC Part 15, Subpart J, Class A; EN55022 Class B; CISPR 22 Class B.
Output Isolation: Isolated from ground 50 Vdc.
Reverse Voltage: Protected against reverse voltage up to supply current rating.
Cooling: Self cooled with internal ball-bearing fans.
OPTIONS:
Option “B”, Barrier Strip: Provides auxiliary output connections on #6-32 terminal screws
with 3/8˝ centers.
Consult factory for other available options.
