47. Series Operation
For series operation, either method (A) or (B) is possible.
In series operation, the actual voltage between output and
must be less than withstand voltage (500VAC).
In addition, take note that using the product with total output voltage 60V or more does not comply with SELV
in safety standard. In series operation, the rising waveform may have steps.
When connecting with a battery, connect an ORingdiode to the output side of the product.

Note :In case of connecting bypass diodes with method (A), please select a bypass diode with maximum
forward current rating more than output load current. And maximum reverse voltage must withstand each
power supply output voltage.
But ensure that all products must be in operation.
(Never use in condition that one of the product is not operated.)
Series operation also can be used without bypass diode.
48. Parallel Operation
(A) Operation to increase the output current is not possible.
(B) Operation as a Backup System
Connect our reverse prevention module "RP6020" or ORingdiode to the output side of the product.
(1) Adjust each product output to same voltage. (The difference of each product output voltage should
be within ±5%.)
(2) Adjust the output voltage higher by the value of the voltage drop (90mV typ.) of RP6020 or the forward
voltage drop (Vf) of ORingdiode.
(3) Output voltage and output power should be used within specifications.
(4) When using RP6020, output load current should be used within specifications. When using
ORingdiode, current rating must be more than output load current.

RP6020 can be replaced by ORingdiode. In such
case, please take care of ORingdiode temperature.
