Details description

Resistance absorber
Introduction	Product Type SM-2B
Electronic arc extinguishers, also known as voltage suppressors, are widely used in the defense, aerospace, machinery, chemical, shipbuilding and metallurgical industries, such as contactors, relays, solenoid valves, etc., which are prone to arcing or inductive coils. In the main circuit and control circuit of overvoltage, it eliminates arc, suppresses overvoltage, absorbs residual energy, limits electromagnetic interference, prolongs the life of electrical components, and ensures the normal operation of microcomputer numerical control system and other control systems. In the case of vigorous development, it is an indispensable electrical accessory.

Product application
Electronic arc extinguishers can be widely used in the national defense, aerospace, machinery, chemical, shipbuilding and metallurgical industries, such as contactors, relays, solenoid valves, etc., which are prone to arcing or inductive coils, which are disconnected to generate overvoltage. And the control circuit, to eliminate the arc, suppress the overvoltage, absorb the residual energy, limit the elimination of electromagnetic interference, extend the life of the electrical components, and ensure the normal operation of the microcomputer numerical control system and other control systems.
