I would like to know how this power transformer can be used to do a dual power supply of + / - 12 volts.
I have worked with a transformer with three cables at the secondary but this has 4, can you please help me?
how the cables should be connected to do the power supply?
Also
How I eliminate a TRANSIENT VOLTAGE, how I filter the input signal (120Vac) because when I turn on a flourescent lamp or I connect a electronic device I have noise in the ground path or my electronic design that my microcontroller (PIC16F870) reads a bad signal.
I am planing to put a varistor and a ceramic capacitor of .1uF in parallel between the AC man line. is it right?
Thanks in advanced, happy new year!
