Control Concepts AC25C is a single-phase AC analog SCR power controller designed for precise load control in industrial heating and transformer applications. This unit supports amperage ratings of 10, 20, 30, 40, and 70A across voltage options of 120, 240, 480, and 575V, with a 4-20 mA analog command signal for control. It features a compact design with natural convection cooling, weighs 5.19 lb, and provides 2500 Vac RMS isolation for robust electrical protection. The controller employs phase angle firing, line voltage compensation, soft-start for transformer loads, and missing cycle detection to ensure reliable operation. Typical applications include electric ovens, furnaces, kilns, and variable resistance loads in demanding industrial environments.
