|
 Input Voltage: |
The range of input voltage is from 72~136VDC |
 |
Input Current: |
The maximum input current is 5A at 110VDC input |
|
Inrush Current: |
The inrush current will not exceed 10A at 110VDC input cold start, 25°C |
|
Load Range: |
At factory, all outputs in 60% rated load condition; the +5V output is set to between 4.80V and 5.20V. The other outputs are checked to be within the specified voltage accuracy range |
|
Ripple and Noise: |
The peak to peak ripple and noise for +5V, +3.3V outputs are less than 50mV, and for the other output are less than 100mV at rated load. Measuring is done by 15MHz bandwidth limited oscilloscope and terminated each output with a 0.47 μF capacitor |
|
Line Regulation: |
The output line regulation for each output is less than +/-1% while measuring at rated load and -40~-72VDC input voltage changing |
|
Load Regulation: |
The output voltage load regulation is less than the values in the following table by changing each output load +/-40% from 60% from rated load, and keep other outputs at 60% rated load |
|
Output Power: |
The total DC continuous power shall be kept within 300W ambient temperature of 40°C below, and input voltage at 110VDC. The maximum, total combined output power on the 3.3V and 5V rails is 150W |
|
Power On Signal: |
This TTL compatible signal (active low) is use to switch ON the main output. When power on is disconnected from secondary common, all outputs except +5Vsb shall turn off |
|
Power Good Signal: |
When power start-up, the power good signal will increase between 100ms to 500ms after all output DC voltages are within regulation limits |
|
Power Fail Signal: |
The power fail signal will fall at least 1ms before any of the output voltages lower than the regulation limits |
|
Efficiency: |
The efficiency is higher than 65% while measuring at nominal line and rated output |
|
Altitude: |
Will operate properly at any altitude between 0 to 10000ft |
|
Protection: |
Over Voltage: For some reasons the power supply might fail to control itself, the build-in crowbar circuit will automatically shut down the outputs to avoid damaging the external circuits. The trip point of O.V.P. circuit is around 5.7V to 7.0V
Short Circuit: The power supply will go into hiccup mode function against short circuit or over load conditions. If the faults condition removed, the power supply will restart automatically |
|
Temperature: |
Operating: 0°~70°C (-20°C can start up, derating from 50°C)
Storage: -40°~+75°C |
|
Humidity: |
The power supply can operate from 5% humidity to 95% humidity non-condensing at 40°C |
|
Connector: |
DC Connectors: 3 positions terminal blocks
ATX: Molex 39-01-2200 or equivalent
Disk Drive: AMP 1-480424-0 or equivalent
3.5" Floppy Driver: AMP 171822-4 or equivalent
P4: Molex 39-01-2045 or equivalent |
|
Dimensions: |
14.0 x 15.0 x 8.62 cm; Tolerance specified is +/-0.4mm between mounting holes and +/-0.8mm for other dimensions |
