Available in sizes ranging from 35 to 700 A, the Aspyre line is flexible, scalable and offered with options that allow one platform to be reused across many applications. The power control line offers multiple advanced microprocessor-based firing and control-mode algorithms. Firing modes include zero cross, burst firing, single cycle, delayed triggering and phase angle. Combined with diagnostics and communications options, the line enables equipment and factory automation. Smart algorithms enable the device to control different load types, including nichrome, moly, silicon carbide, tungsten quartz and infrared lamps and transformer-coupled loads. It also protects and extends the life of connected loads. Modular options include controlled legs (1, 2 or 3), semiconductor fusing, load current measurement, amperage size and user interface. The robust SCR design meets the quality and reliability needs of rugged industrial environments.
