Condor’s MPS-350 multiple output
switching power supplies are the ideal
solutions for critical applications such as
communications equipment and industrial
controls. These often require parallel
power sharing for expandable systems or
redundant power supplies for “fail-safe”
reliability. With Condor’s innovative “zero
wire” power sharing technique, these
switchers will provide a highly reliable
power sharing system.

The MPS Series utilizes proprietary
technology that does not require extra
connections to achieve redundancy or to
share power. This technology ensures
that all of the working supplies stay “on”
and deliver current to the load, allowing
no glitches. The load sees consistent reg-
ulated voltage before, during, and after a
power supply failure. With our MPS
Series, the user enjoys highly reliable
power sharing, glitch-free performance,
and minimum complexity.
You can build any number of these
switchers into your system to allow paral-
leling for additional power or N +1 re-
dundancy. The switcher can also be used
alone as the basic building block power
supply for future system expansion.
Housed in a low-profile, open frame
configuration measuring only 9” x 5” x
2.5”, the MPS delivers 350 watts of
power with a main output of 5 Volts at
50 Amps. The unit is designed to be
cooled with system air or through an
optional fan/cover assembly.
Other features include: Overvoltage
Protection, Overtemperature Protection,
Soft Start, Remote Inhibit, Remote
Sense, Overcurrent Protection,
DC Power Good and Auto-Ranging.
Fan/covers are also available.
If your design calls for power sharing,
redundancy, or expandability, check out
the important features and specifications
of this Condor switcher for a truly reliable,
optimum power sharing system.

SPECIFICATIONS: ALL MODELS
INPUT
AC Input:
90-132 Vac/180-264 Vac, 47 to 63 Hz. User selectable. See option “A” for automatic
line selection. Internally fused for 10 A.
Inrush:
Cold start AC current is less than 10 A at 115 Vac and 18 A at 230 Vac. For MTX
models, 10 A at 115 Vac and 20 A at 230 Vac. Limited by thermistor.
Holdup Time:
16 ms minimum after removal of power, at nominal line, full load.
Efficiency:
80% typical.
Brownout Protection:
Holds regulation to 85 Vac or 170 Vac.
OUTPUT
Adjustability:
All outputs user adjustable ±5% minimum.
Line & Load Reg
(Output #1): ±3% over AC input range and 10 to 100% load change
(preprogrammed slope). 10% minimum load required.
Line & Load Reg
(Other outputs): ±1% over AC input range and 0 to 100% load change. No
minimum load required.
Ripple & Noise:
Less than 1% p-p or 100 mV, whichever is greater.
Remote Sense
(Output #1): Compensates for 250 mV total line drop. Open sense lead
protection. (See Redundancy, below.)
Temperature Coefficient:
0.02% per degree C.
Stability:
0.1% over 8 hours after 30 minutes warm-up.
Transient Response:
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
(Output #1): 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 drops output power to nominal
zero.
Redundancy:
External OR-ing diodes and slope program current sharing on output #1 provide
“N+1” capability. Remote sense (+S) compensates for additional 0.6 V diode voltage drop.
Current sharing remains within 10% of the unit’s full output current rating.
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.
Output Isolation:
Isolated from ground 50 Vdc.
Cooling:
30 CFM required to achieve full ratings.
Option “F”, Fan/Cover Assembly:
Cover with integral ball-bearing fan provides proper cool-
ing to achieve full ratings at 50°C ambient temperature.
Option “G”, DC Power Good:
Provides a TTL “1” open collector when output #1 is above
4.6 V nominal. Not available if option “P” is selected.
Option “P”, AC Power Fail:
Provides TTL “0” 5 ms before output voltage goes out of
regulation band upon loss of ac power. VMEbus compatible, provides 48 mA sink current
capability. Not available if option “G” is selected.
Option “V”, Fan/Cover Assembly:
Low profile, end venting cover with integral ball-bearing
fan.
Consult factory for other available options.
