Unison is a Manufacturer and Global supplier of Solid state relays (SSR) for many industries. The company was incorporated in year 1992 and since inception we set a vision for the company to be one of the prominent manufacturers of Solid State Relays. Accordingly, after fully absorbing the know-how of different industries and accepting our Customers as “GURU”, we understood their needs and translated their inputs into fertile ideas. After that, we expanded our portfolio in varied control relays.
