Just remember when AC is rectified the output voltage will be 1.4 times the output voltage as the AC voltage is rated as an average voltage of the sinewave so 15 voltas ac will be 21 volts DC this could be too high to run the LED’s All the type of bridge rectifiers that you state the inner pins are for connecting to the AC input.

While the engine runs on AC, it also runs very nicely on DC. The hum is a lot less and very smooth operation. Check it out.

By the way, if you just connect the bridge rectifier AC pins to the transformer and it is “shorting” that bridge might be faulty internally.

Like mentioned above, the middle pins are AC input.

I don’t know if you can check the proper operation of the rectifier, if you connected it backwards it may be broken?

So if your LED strip is designed for DC use, it should be connected to the outermost leads, watching the polarity of course.
