West Control Solutions PMA Relay thyristor power controllers come in a variety of sizes from 3A to 2,600A and 690VAC. They are used with process loads that are constant or variable resistance, inductive or transformer coupled or single or 3 phase. The controllers provide a frontal key pad for configuration, enabling them to be set up in situ. They are compatible with RS 486 communications and have a USB port for the setup of multiple controllers.
