−
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 l/-40%
from 60% rated load, and keep other output at 60%
rated load.
