Hello,
I'm troubleshooting a circuit that has a step down AC transformer and I'm confused about the voltages I'm reading in the secondaries.
The specs are:
INPUT: 110V AC 50Hz/60Hz
OUTPUT: Yellow 15.5V / Black 9.5V
When I measure the outputs with the secondaries disconnected from the circuit I get around 16V in the yellow and 10V in the black, which is good. But when I measure with them connected to the circuit I get 4.4V in the yellow and 7.6V in the black.
Aren't the outputs supposed remain the same no matter if the secondaries are connected to the circuit or not?
Thanks for the help.
