What is a solid-state relay (SSRs) / solid state contactor (SSCs)?
A solid-state relay (SSR) or solid-state contactor (SSC) is an electronic component that switches power (AC or DC current) to a load circuit and provides electrical isolation between an application’s control circuit and load circuit. It is a competitive technology to electromechanical relays (EMRs) and other switching technologies such as mercury displacement relays (MDRs). Why use solid state switching technology? Long service life Quiet operation Minimum electrical noise Low power consumption Shock & vibration resistant Ideal for harsh environments High compatibility with control systems Reduced weight Position insensitive Fast switching Magnetic noise immunity Reduce energy cost Solid state relays & solid-state contactors applications Although there are literally thousands of individual uses for solid state relays and solid-state contactors, most can be categorized into the following applications: Heating control application This encompass...
