RS Pro Anti-Surge Noise Product
Surge/noise prevention parts are for preventing surge and noise that cause circuit part damage and malfunctions. Surge/noise prevention parts include spark killers, surge protectors and surge suppressors. A spark killer has a structure where a capacitor and resistor are connected in a series, and is used to protect against reverse voltage surges caused by an inductor and sparks generated between switch contacts. Spark killers compliant with the main international safety standards are also available, enabling use in devices that are exported. The marks for the certified safety standards are printed on the package surface. Surge protectors are components that prevent inductive lightning from the AC power supply. Its circuits are comprised of metal oxide varistors and GDT, and a feature is its fast response to sudden rising at startup. Single-phase and three-phase power supply types are available, which can be used in a wide range of devices such as NC lathes, machine tools and industrial equipment.
