Parallel Application Circuit
The R-52xx, R-53xx, R-54xx series can be used in parallel to upgrade the output current capacity for
the same output voltage.
For example, the R-543.3PA can parallel up with another R-554.3PA to give up to 8 amps or with the
R-533.3PA or R-523.3PA types to give output currents of up to 7 Amps or 6 Amps.
The R-55xx series cannot be paralleled.
