An electrical transformer is a static device which is used for the transformation of AC electrical signal in one circuit to the electrical signal of the same frequency in another circuit with a little loss of power. The voltage in a circuit can be increased or decreased, but with a proportional increase or decrease in the current ratings. Type 12-0-12 transformer 3amp current output with screw clamp for easy setup low noise high efficient. 12-0-12 Volt 3 Amp transformer an ideal choice for powering home theaters and audio amplifiers, ensuring reliable and high-quality audio performance.
