Description
905 3PH ZDA 48 40 01: The Unison 905 3PH ZDA 48 40 01 is a high-performance 3-phase solid state relay (SSR) designed for reliable switching of three-phase AC loads using a DC control signal. With a 4-32VDC input and 24-480VAC output rating up to 40A, this SSR provides fast, silent, and maintenance-free operation for industrial automation applications. The relay utilizes zero-cross switching technology, helping to reduce electrical noise and minimize stress on connected equipment during switching operations. It is suitable for applications where frequent switching and long service life are required. The model is supplied without a heat sink base, allowing users to select a suitable heat sink according to their installation requirements and load conditions. Features such as opto-isolation, inbuilt snubber circuitry, and surge protection enhance reliability in demanding industrial environments.
