SSR1200480D90 is a Series S solid-state relay manufactured by Teledyne Relays, designed for AC/DC control applications with a 480 Vac line voltage and zero-cross turn-on switching type. The relay supports a maximum output current of 90 A (resistive load) with an operating voltage range of 24 to 520 Vrms and a peak voltage rating of 1200 Vpeak. It features an on-state voltage drop of 1.3 V at rated current, a turn-on time of 8.3 ms at 60 Hz, and a turn-off time of 8.3 ms, with thermal characteristics ranging from 0.3°C/W to 2.2°C/W depending on load conditions. The relay is suitable for industrial control applications including motor control, heating element switching, and power distribution systems where reliable AC switching and thermal management are essential.
