Designed to meet applicable Bellcore and
NEBS standards, the DMX Series 500-watt
power supplies require DC input. They are
DC “clones” of Condor’s popular NMX 500
Series of AC power factor corrected power
supplies. This gives you the ability to
operate existing systems from central
office power (–48 Vdc) simply by changing
power supplies.
DMX and NMX Series power supplies
are directly interchangeable, without
compromising performance and without
making any mechanical changes for
mounting or cooling. DMX and NMX Series
power supplies can also be operated in
redundant configurations to achieve AC
operation with battery backup capability.

SPECIFICATIONS: ALL MODELS
INPUT
DC Input: 40-60 Vdc range. Internally fused for 25 A.
Efficiency: 75% typical.
OUTPUT
Adjustability: Outputs #1 and 2 user adjustable ±5% minimum. Output #3 tracks #2; initial
accuracy ±4%. Output #4 user adjustable ±5% minimum.
Line & Load Reg: Outputs #1, 2, and 4 hold ±1% over DC 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 overvoltage. 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.
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 among units, current sharing remains
within 10% of the unit’s full output current rating.
DC Power Good: Provides a TTL “1” open collector when output #1 is above 4.6 V nominal.
Reverse Voltage: Protected against reverse voltage up to supply 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.
Cooling: 30 CFM required to achieve full ratings.
Output Isolation: Isolated from ground 50 Vdc.
