Hi,
for a simple little fixed power supply +-15V @100mA I would like to use a small print transformer. However, being a prototype, I don't want to invest in a PCB.
Is it possible (from a safety point of view) to use a perfboard (dot PCB)?
To get the required clearance I would remove two rows of dots around each 230V trace / four rows between primary and secondary side.
Beside the mains terminal and the transformer there wouldn't be any other components on the mains side (primary fuse holder is mounted in the case).
The whole thing will be mounted inside a fully closed and mains earthed aluminium case. The secondary side would be floating and accessible to the outside.
Is that safe to construct this way?
Best,
Peter
