Series Operation - TDK-Lambda ZWS300RC Series Instruction Manual

6-6. Output Ripple & Noise
The specified maximum ripple & noise value is measured according to below measurement circuit. When load
lines are longer, ripple will becomes larger. In this case, electrolytic capacitor, film
capacitor, etc. might be necessary to be used across the load terminal.
The output ripple cannot be measured accurately if the probe ground lead of oscilloscope is too long.
