ps102
Info
I was repairing a power supply used by the museum at
which I volunteer. It was an ER brand, model PS102
power supply, 13.8 V, 5-7 Amp output with short circuit
protection (supposed to be 5A continuous and 7A peak).
This same item was sold under the same model number by
several vendors (not just ER). I couldn’t find a
schematic online (though I found a few seekers). I was
able to get the Chinese maker to send me a diagram of
the later model PS107 & I worked out the differences to
obtain a schematic for PS102. The schematic is
attached in case you think it would be useful to archive.
