6­8. Output Ripple
&
Noise
The standard specification for maximum ripple value is measured according to measurement circuit specified
by JEITA­RC9131C. When load lines are longer, ripple will becomes larger. In this case, electrolytic capacitor,
film capacitor, etc. might be necessary to use across the load terminal.
The output ripple cannot be measured accurately if the probe ground lead of oscilloscope is too long.
6­9. Series Operation
For series operation, either method (A) or (B) is possible.
Method (A) Method (B)
Note : E nsure that all units must be in operation. (Never use in condition that one of the units is not
operated.)
When connected the bypass diode, please select a bypass diode with maximum forward current
rating more than output load current. And maximum reveres voltage must withstand each power
supply output voltage.
