A few people in China know about what is the different between linear power supply and Transformer, they are confused about it.
If it is a transformer, literately speaking, this is AC to AC transform progress; they cannot be a DC power at output side.
If it is a power supply, then, it should have both function, AC to AC and AC to DC, or DC to DC. The range is much wider.
A power supply can be a transformer.
But a transformer maybe is not a power supply.
The great news is:
We had got passed for the even AC to AC or AC to DC testing under EMC, LVD, and ROHS.
And we got the certificate.
