Signal Input (220V) – It is an alternating current, which is defined as currents that reverse their direction periodically. Electric power is usually supplied in the form of 60-cycle-per-second alternating current. The signal input is responsible for powering up the system.

Transformer (step down) - For alternating currents, the job of changing voltage from one value to another can be done easily and cheaply by a transformer. A step-down transformer, which steps down the voltage supplied by the source, is the type used in household circuits. Meaning, if the supply of voltage is 220 volts, the voltage delivered to the customer's home is 110 volts.

Circuit Breaker – it is a safety device consisting of a strip of metal encased in a container that is inserted in an electric circuit. When the current becomes excessive, the strip will melt and it will break the circuit.

Rectifier – A rectifier is necessary to convert a signal having zero average value to one that has...
