DCS industrial solid state relay, 1-phase. Zero switching mode. 230 VAC RMS rated operational voltage. 3 to 32 VDC control voltage. 50 A AC RMS rated operational current. 650 Vp blocking voltage. 10 V zero voltage turn-on. 45 to 65 Hz operational frequency range. -20 to 70°C operating temperature. Direct copper bonding (DCB) technology. LED indication. Built-in varistor. Clip-on IP20 protection cover. Self-lifting terminals. Housing free of moulding mass. Offers a comprehensive range of solid state relays (SSR's) featuring direct copper bonding technology for increased life and reliability. SSR's 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.
