Watlow PC11-F20B-0100 Solid State Power Controller

The Watlow PC11-F20B-0100 solid state power controller delivers precise SCR-based load control for high-power thermal applications, making it suitable for industrial power switching in systems that require accurate electrical management at 480V and 125A. Part of Watlow’s Power Series, this 480V AC single-phase SCR power controller supports Zero Crossing and Phase Angle firing, operates at 50/60 Hz, and communicates via Modbus RTU for automation network integration. It mounts on a back panel, provides a 200 kA short-circuit current rating, and offers heater and control diagnostics to aid maintenance and safety checks. Built-in semiconductor fuse protection helps safeguard the load and controller, while an operating range of 0°C to 85°C suits typical industrial environments; it is certified to UL, C-UL, and CE standards. Typical applications include industrial ovens, heat treatment systems, plastics processing equipment, industrial furnaces, process heaters, semiconductor manufacturing equipment, and OEM thermal control panels, where accurate SCR power regulation and load control drive consistent thermal performance.
