Requirements for power supply
Is the power used by OPTO22’s S1, R1 and EB1 to be linear? Can the switching power supply with good quality be used?

@zhhpei Please review the Opto22 power supply recommendations document;

So to answer your question directly, no, you do not have to use a linear supply, a good quality switching supply is fine.
The SNAP-PS5 is what we recommend and it is a switching supply.
