Dead, when in turn on MCB PLN plummeted.
Measurement travo and input cable.
Travo was burnt,and occur short circuit.
Replace travo 3 amperes with 5 amperes.
Pairs of primary voltage at 240V then secondary voltage at 25V.
The goal is power is needed nothing less, travo lighter works.
Do not enter any the input signal.
Measuring currents using Ampere meter, currents should be close to 0 amperes.
when the magnitude of the current is close to 0 amperes, then it's ready to use.
