(III) +48V DC Power Supply
Input Specifications
$"
Input voltage range: +36VDC to +72VDC
$"
Input current: 3A at +48VDC max.
Output Specifications
$"
Load Range:
Output Min. Load Rated Load Voltage Accuracy
+5V 0A 10A 4.95V to 5.05V
+12V 0A 1.5A 11.4V to12.6V
-12V 0A 0.3A -11.4V to –12.6V
At factory, all outputs in 60% rated load conditions, the
+5V output is set to between 4.95V and 5.05V, and 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 output is less
than 60mV and less than 100mV for +/-12V outputs.
Measuring is done by 15MHz bandwidth limited
oscilloscope and terminated each output with 0.47uF
capacitor.
$"
Line Regulation:
The line regulation for +5V output is less than +/-1%, for
+12V is less than +/-2%, for –12V is less than +/-3% while
measuring at rated loading and +/-10% of input voltage
changing.
$"
Load Regulation:
The load regulation for +5V is less than +/-3%, for +12V is
less than +/-5%, -12V is less than +7% -3%, measuring is
done by changing the measured output loading +/-40%
from 60% rated load, and keep other output at 60% rated
load.
