The output range of +12V, -12V and down with +5V setting.
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 50mV and less than 100mV for +/-12V outputs, both at
rated loads. 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, +12Vare less than +/-3%, for
-12V is less than +/-5%, measuring is done by changing the
measured output loading +/-40% from 60% rated load, and
keep other output at 60% rated load.
