TDK-Lambda
RDS Series (110VDC Input)
Instruction Manual
6-9. Output Ripple & Noise
The specification for maximum ripple &noise value are measured according
to measurement circuit specified by JEITA-RC9131B.
Output Ripple & noise level will be large when a load line is long.
In such case, it might be necessary to connect electrolytic or film capacitor
across the load terminal. The output ripple cannot be measure accurately
if the probe ground lead of oscilloscope is too long.
6-10. Series Operation
For series operation, either method (A) or (B) is possible.
(*1) In case of (A), please connect bypass diodes to prevent reverse voltage. 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.
6-11.
Parallel Operation
The RDS50-110 can be used for Back-up Operation as (A) by setting output voltage same each other. For the (A), please connect
By-pass diodes which have the rating forward current of load current or more, and reverse voltage more than output voltage.
Furthermore, Parallel operation for higher power output cannot be used.
6-12. Isolation Resistance Test
Isolation resistance is more than 100MΩ at 500VDC between Output - (Protective Earth), and 10MΩ at 100VDC between Output –
CNT/TOG. For safety operation, voltage setting of DC isolation tester must be done before the test. Ensure that the unit is fully
discharged after the test.
