Transformer with following specs:
Prim 220V Sec 36V CT
Power 50 VA
After implementing a diode bridge and a 2 x 5000uF filter, I measured first:
- 25,4V - 0 mA
-23,7V - 270 mA
-22,4V - 620 mA
-21,3V - 1000 mA
and later:
+25,4V - 0 mA
+23,7V - 250 mA
+22,6V - 620 mA
+21,3V - 1000 mA
Ridiculous as it sounds a big box with power resistors is missing from my bench thus the separate test of each branch.
I tried to come up to 1390 mA but after burning several small value resistors I decided to stop.
I always get confused about the VA spec for CT transformers, thus my question: provided the specs are true, how much current (maximum possible) should I obtain from each output at the same time?
1390 mA or just 695mA?
