47 to 63 Hz |
| Power factor |
0.99 typical at full load. Meets EN61000-3-2 |
| Inrush |
Cold start ac current is less than 15 A at
115 Vac, and 60 A at 230 Vac. Limited by thermistor |
| Brownout Protection |
Holds regulation to 85 Vac (30 seconds maximum) |
| Holdup Time |
16 ms minimum after removal of power at full
load. 10 ms minimum for cPCI 200s |
| Efficiency |
70% typical |
| EMI: Conducted RFI |
Meets FCC Part 15, Subpart J, class A; EN55022
class A; CISPR 22 class A |
| Fail # Signal |
TTL compatible signal. Signal goes low under
the following conditions: |
| |
Outputs #1 or #2 fail |
| |
an overcurrent condition on outputs #1, #2,
or #3 |
| |
an overtemperature shutdown |
| |
an overvoltage shutdown |
| |
an ac input failure (5 ms warning before
outputs shutdown) |
| Output |
|
| Line and Load Regulations |
+/-2% over input range and 0 to 100% load
change |
| Ripple & Noise |
1% p-p or 50 mV, whichever is greater |
| |
measured at mating connector with 20 uF |
| Remote Sense |
open sense lead protection |
| Temperature Coefficient |
(Outputs #1 and 2): 0.03% per degree centigrade |
| Stability |
0.1% over 8 hours after 30 minutes warm-up |
| Transient Response |
(outputs #1 and 2): |
| |
Output voltage returns to within 1% in less
than 1 ms for a 50% load change. |
| |
Peak transient does not exceed 5% |
| 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 |
| |
Input power must be recycled to reset. |
| Overload Protection |
All outputs are protected against overload
and short circuit |
| |
automatic recovery upon removal of fault |
| DEG # Signal |
TTL compatible signal. Signal goes low 20
degrees C before an overtemperature shutdown |
| Fail LED |
Amber LED illuminates upon a failure condition
as per series specifications |
| Status LED |
Green LED illuminates with no presence of
any failure condition |
| Remote Enable |
Contact closure to the negative sense line
or a TTL level "0" turns off dc outputs |
| Redundancy |
Built-in ORing diodes, slope program current
sharing on all outputs, and self aligning connector provide
hot swap and N+1 capabilities. |
| |
Current sharing remains within 10% of the
unit's full output rating while units are in thermal equalibrium |
| Reverse Voltage |
protected against reverse voltage up to supply
current rating, except for reverse voltage on output #4 |
| Environmental |
|
| Cooling |
15 cfm, 225 lfm airflow required for cooling |
| Output Isolation |
Isolated from ground 50 Vdc (leakage current <20
uA) |
| Thermal Protection |
Shuts down power supply if overheated |
| |
Automatic recovery |
| Temperature Range |
0 to 40 degrees centigrade at full ratings |
| |
derate 2.5% per degree centigrade from 40
degrees to 70 degrees centigrade |
| |
unit will start up at -20 degrees centigrade |
| MTBF |
421,408 hours |
| Miscellaneous |
|
| Safety Agency Approvals |
