Specifications
Input Voltage
Power Fail Signal
The range of input voltage is from 10~30VDC, nominal input
voltage is 12 and 24VDC
Input Current
The power fail signal will go low at least 1ms before any of the
output voltages fall below the regulation limits
Efficiency
The maximum is 18A at 10VDC input
Inrush Current
The efficiency is higher than 70% while measuring at nominal line
and rated load
The inrush current is less than 30A at 10VDC input
Load Range
Altitude
0~10,000ft
At the factory, the +5V output is set between 5.08V to 5.13V and
all output at 60% rated load; the other outputs are checked to be
within the accuracy range. The maximum total combined output
power on the +3.3V and +5V rails is 70W. The max. load connot
exceed 120W
Protection
The power supply will generate the hiccup mode to protect itself
against short circuit or over load condition, and will return to
normal after wrong condition is removed
Temperature
0~+50oC, outpur power is 120W forced air cooling, 80W
convection cooling (operating); -20~+70oC (storage)
Ripple And Noise
The peak to peak ripple and noise for +5V, +3.3V output are less
than 100mV for +5Vsb is 120mV, for +12V is less than 120mV, for Humidity
-12V is less than 200mV at ranted load and nominal input, which is 10~90% non-condensing
measured by a 20MHz bandwidth limited oscilloscope and the each Connectors
output is connected with a 0.47uF capacitor
Line Regulation
DC Input: Dinkle DT-35-B01W-03 or equivalent
DC Output: Molex 5273-14A or equivalent
The line regulation is less than +/-2.5% at rated load with +/-10% DC Output: Molex 5045-03A or equivalent
change in input voltage
Power Good Output: Molex 5045-02A or equivalent
Load Regulation
Fan Output: Molex 5045-02A or equivalent
The load regulation for +5V is less than +/-2%, for +12V is less
than +/-5%, for -12V +/-5%, +3.3V is less than +/-5% while the
measuring is done by changing the measured output loading
+/-40% from 60% rated load, and keep other output is at 60%
rated load

Power On/Off
The power supply will start-up when the power On/Off pin be
connected to secondary GND

Dimensions
Power Good Signal
8.38 x 15.24 x 3.81 cm; tolerance specified is +/-0.4mm
The power is turned on, the power good signal will go high between
100ms to 500ms after all output DC voltage are within regulation
limits
