•
N+1 redundant power supplies (N = 3), delivering a minimum
of 200W each throughput from the Dual Power Input Module
system, should share current load on all DC outputs.
•
DC Dual Input Power Module system provides full redundancy
of input power components.
•
Total chassis load supported by the subsystem is 500W at
ambient of 40
0
C.
•
Power supply interface is compliant with PICMG 2.11, R 1.0,
with the 47 pin Positronic interface.
•
DC input range is –42 to–68VDC.
•
Internal Power Factor Correction (PFC) meets IEC EN61000-3
requirements for harmonic distortion and flicker.
•
Individual maximum loads (per power supply module) are as
follows:
+5VDC @ 25A
+3.3VDC @ 20A
+12VDC @ 5A
-12VDC @ 0.5A
•
Minimum load for +5VDC of each power supply module is 3A.
•
Combined maximum output current of +3.3VDC and +5VDC
shall not be more than 30A per power supply module.
•
Maximum allowable ripple does not exceed:
75mV for +5V and 3.3V
150mV for +12V
150mV for –12V
•
Load Regulation is:
+/-5% for +5V, +3.3V and +12V
+/-10% for –12V
•
Power Supply MTBF is at least 100,000 hrs, operating full load
at 25
0
C (MIL-217).
