Picker Components Solid State Relays PCS34-D-240A-25RYL

The PCS34 series is a DC input solid state relay with SCR output, load currents from 40 to 125 A, and load voltage ranges up to 660 VAC. It features 4,000 VAC dielectric strength between input and output, optical isolation, zero-crossing or random turn-on switching, and an integrated status LED. The device is housed in a fully epoxy-resin-filled case with screw terminals, weighing 95 g for 40 A to 80 A models and 130 g for 100 A to 125 A models. It has a maximum on-state voltage drop of 1.7 Vrms, thermal resistance junction-to-case from 0.13 to 0.25 °C/W, and operates from -30°C to 80°C. The part includes varistor overvoltage protection and requires a heat sink for reliable operation. Dimensions are 58 mm × 42 mm × 54.9 mm.
