Carlo Gavazzi offers a comprehensive range of Solid State Relays (SSRs) featuring direct copper bonding technology for increased life and reliability. SSRs are used extensively in the plastics, packaging, food processing, and HVAC industries - primarily for temperature control. Other applications include lighting and pump switching. Many of our relays feature horsepower ratings, that make them suitable for controlling motorized dampers in HVAC control systems. In these particular systems, our relays are the ideal replacements for mechanical contactors, because of their long life and noise-free switching. Furthermore, we also offer a complete range of SSR's with a built-in heatsink.
