Control Concepts LPAL22 is a single phase analog SCR power controller designed for precise phase angle control of AC loads. This controller supports amperage sizes from 10 to 70 amps and operates at voltages of 120, 240, 480, or 575 volts AC, with a weight of 5.19 lb. It features phase angle firing mode with line voltage compensation, soft-start for transformer loads, and missing cycle detection, while providing 2500 Vac RMS isolation between input/output and line voltage/heatsink. The device accepts analog command signals such as 0-5 VDC, 0-10 VDC, or potentiometer input and is convection cooled for reliable industrial use. This compact and economical controller is suitable for electric ovens, furnaces, kilns, and variable resistance loads.
