| Output Voltage/Current |
5V/40A, 3.3V/40A, +12V/9A, -12V/2A |
| Output Power |
350 Watts |
| Input Voltage/Current |
48 Vdc (40-72 Vdc tolerant range), 12 A max |
| Power Factor |
0.99 typical |
| Inrush Current |
AC: 40A max |
| Efficiency |
DC input: 75% typical (73% min at 40 Vdc
input) |
| 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,and +12V currents to within
20%. Remote sense must be used when operating in parallel
with current sharing. |
| Redundant/Hot Swap |
Full power N+1 redundant and hot-swap |
| Remote Sense |
Compensates for up to 0.25V total distribution
voltage drop on the 3.3V/5V/+12V outputs |
| Line/Load Regulation |
0.5% max. over input range and 0-100% load
except -12V output which is +/- 10% |
| Mininum Load |
None required |
| Ripple/Noise |
50 mV max. for all outputs, peak-to-peak,
dc to MHz with coaxial probe and 0.1uF/22uF capacitors at
the connector |
| Overshoot/Undershoot |
Less than 2% at turn-on, turn-off or restart |
| Turn-on Time |
1 sec max. from power up. All output voltages
come up within 10 msex. of each other. |
| Over-Voltage |
Shutdown at 125% of nominal Vout. Recycle
input 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 CE marked |
| EMC |
EN55022 Class A conducted approved |
| Input Fuse |
Internal fusing included |
| Output Isolation |
All outputs and control signals are floating
SELV circuits referenced to GND with reinforced insulation
to the AC primary. Can be connected directly to chassis ground
on the system backplane |
