| 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 |
Line: At the sence point, over full input range <+or-1%, sense leads connected.
Load: Output voltage drops with increasing load.
|
| Ripple & Noise |
For all outputs, 50mV max or 1% peak-to-peak nomical, which ever is greater, DC to 20MHz bandwidth with a coaxial probe and 0.1μF/22μF capacitors at the output terminals. |
| |
measured at mating connector with 20 uF |
| Remote Sense |
V1, V2, V3 outputs compensate for up to 0.25 total line drop in the load cables. Outputs are internallly sensed if leads are opened |
| Temperature Coefficient |
<±0.02%/ºC, 0º - 50ºC, after 20 minute warm-up. |
| Stability |
Output drift <±0.2% after 20 minute 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 |
Non-crowbar type. Any output that exceeds 25% ±10% of nominal Vout will cause all outputs to latch off. Remote inhibit, enable or input recycle required 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 |
Enabled by closed circuit or TTL logic 0.
Disabled by open circuit or TTL logic 1. |
| 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 |
3U 4HP: A minimum of 600 lfm (800 cfm) direct forward airflow required to achieve full rated power and specified MTBF. Consult factory for derating guidelines with reduced or reversed airflow.
3U 6HP:
A minimum of 400 lfm direct forward airflow required with the optional external heatsink.

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 |
