Description
The PCI 350 is a high-performance power supply
for use in 6U CompactPCI computer, test and telecom
systems. The PCI 350 meets all of the requirements
of the PICMG CompactPCI specification plus N+1
redundant and hot swap. High-density cooling fins
are positioned directly in the airstream. All input
and output connections are through the
backplane. LED status indicators are located on
the front panel.

Power
Over-Voltage
............................................ Shutdown at 130% of nominal Vout. Recycle power to
reset
Over-Temperature.................................
Shutdown upon internal heatsink temperatures
exceeding limits. Recycle power to reset
Current Limiting
..................................... All outputs protected against overload and short circuit.
Straight-line current limiting, does not fold-back or latch-
up during startup or load transients. Automatic recovery
Safety.
.......................................................... UL, cUL, and CB report UL1950 and EN60950
EMC
............................................................... Emissions below EN55022 class A and EN61000-3-2, 3.
Immunity to EN61000-4-2, 4, 5
Input Fuse.
................................................. Internal fusing included
Output Isolation......................................
All outputs and control signals are SELV circuits
referenced to GND with reinforced insulation to the AC
primary. GND should be connected to chassis ground
in the system.
Leakage Current
..................................... 1.0 mA max. at 240 Vac
Dielectric Strength.................................
AC: 2200 Vdc from input to chassis ground
DC: 500 Vdc from input to chassis ground
Indicators
................................................... Green LED indicating INPUT OK

Output Power...........................................
DC Input:
AC Input:
350 Watts max
350 Watts max 105-264 Vac
300 Watts max 90-105 Vac
Input Voltage/Current
......................... AC: 100-240 Vac (90-264 Vac tolerant range), 47-63Hz,

DC: 15A max
Efficiency
.................................................... DC input: 75% min
AC input: 65% min
Efficiency increases with line voltage
Holdup Time
............................................. 20 msec min. from input power failure until FAIL# signal
drops, at full load and 90-264 Vac
AC Fail Warning.......................................
5 msec min. continued operation after FAIL# signal drops
Paralleling..................................................
Any number of power supplies can be operated in
parallel and will share 3.3V/5V/+12V current to within
10%. Remote Sense must be used when paralleling
with current sharing
Redundant/Hot Swap...........................
Full power N+1 redundant and hot-swap
Remote Sense...........................................

-12V output which is ±10%
Minimum Load.........................................
None required
Ripple/Noise
............................................. 50 mV max. for all outputs, peak-to-peak, DC to 20 MHz
with coaxial probe and 0.1uF/22uF capacitors at the
connector
Overshoot/Undershoot
....................... None at turn-on or turn-off
Turn-on Time
............................................ 1 sec max. from power up. All output voltages come
up within 10 msec of each other.
