OVERALL
PERFORMANCE: |
| 3.1 |
TOTAL
OUTPUT POWER :260W (full load nominal input voltage) |
|
The
Power Supply's total output power will have to be larger if the |
|
requirement
for power dissipation at the output's Oring devices is taken |
|
into account.
260W is the actual net power required by the load. |
|
Both outputs
should feature Oring elements. |
|
|
| 3.2 |
EFFICIENCY
:65 % typical at full load nominal input voltage |
|
|
| 3.3 |
HOLD
UP TIME : 16 msec at max load and nominal line voltage. |
|
|
| 3.4 |
SWITCHING
FREQUENCY : 85 kHz minimum. |
|
|

|
TEMPERATURE
COEFFICIENT : +-0.05% per.C |

FEATURES: |
|
|
| 4.1 |
OVERVOLTAGE
PROTECTION: When V1 or V2 outputs |
|
exceeds
overvoltage set/trip point (120% to 130% of nominal voltage), |
|
the entire
power supply shuts down. To reset, cycle input power. |
|
|
| 4.2
|
SHORT
CIRCUIT PROTECTION (Individual Outputs) : All |
|
outputs
are protected. Output recovers when short is removed. |
|
|
| 4.3 |
CURRENT
LIMITING (Individual Outputs):Limited to 110%- |
|
135% maximum
output current ratings. Output recovers when overload |
|
is removing
|
|
|
| 4.4
|
OVER
TEMPERATURE PROTECTION: Power supply protected |
|
in the
event of excessive operating ambient degree C, and should be |
|
automatic
recovery when the temperature was back to normal |
|
temperature
in specification. |
|
|
| 4.5 |
REMOTE
SENSE: Separate sense terminals V1 and V2 will |
|
compensate
for total line loss of 5%. Internal circuits assure that the |
|
output
voltage will only change slightly should the sense line open.
|
|
The
compensate value are up to 0.165 VDC at 3.3v and 0.6v at 12v. |
|
Both outputs
will be Oring elements, and the 3.3V output should also |
|
feature
Load Current Sharing via single wire current sharing method. |
|
Parallel
connection capability with " Current Sharing" for up
to 4 units |
|
(total
available power 1040W). |
|
|
| 4.6 |
REMOTE
ON/OFF - ENABLE/INHIBIT: On: Leave circuit open |
|
or apply
TTL "HI". Turn Off: Apply a "TTL" "LOW"
or short pin |
|
to
return. |
|
|
| 4.7 |
DC
GOOD LED INDICATOR: Green LED On indicates ALL DC |
|
outputs
is Good at front panel and should be become dark when has any
|
|
abnormal
voltages at both outputs. |
