R1: Noise reduction resistor

A varistor is required to protect against lightning surges and static electricity.

ZNR: Varistor

Use a rectifying diode with a peak reverse voltage of 1kV or higher, an average rectification current of 1A or larger and a peak surge

current of 20A or larger. When using a large capacitance input capacitor, select a component that endures the is strong

against inrush current during power up. Full-wave rectification can be used.
