Solid State Relay (SSR): High-Performance Contactless Switching Solutions

An SSR (Solid State Relay) is an electronic switch that uses semiconductors, such as MOSFETs or Triacs, to control power circuits without mechanical parts. This allows for Zero Voltage Switching that prevents arcing, wear, and noise. Exceeding 100,000 hours of lifespan, SSRs are best used in high-frequency switching applications, like CNC machines and lights, and harsh environments, like dusty or corrosive ones. They work best at low volts under mA level currents because they can be easily integrated with PLCs or microcontrollers. This ensures lower system complexity while guaranteeing reliability compared to electromechanical relays.
