Modular and Scalable Power Controller Line Ideal for a Wide Range of Applications

aspyre power controller
Watlow’s new ASPYRE power controller family is flexible and scalable, and available with a variety of options allowing one platform to be re-used across a wide range of applications, which can help save time and money. ASPYRE models available include sizes from 35 to 700 amps.

This power controller family features multiple advanced microprocessor-based firing and control mode algorithms. Combined with diagnostics and several communications options the product enables equipment and factory automation.

Controller firing modes include zero cross, burst firing, single cycle, delayed triggering and phase angle. These smart algorithms enable the product to easily control a wide base of heater loads including Nichrome®, moly, silicon carbide, tungsten quartz and infrared lamps and transformer-coupled loads. ASPYRE offers a comprehensive list of modular options that deliver space and labor savings including controlled legs (1, 2 or 3), semiconductor fusing, load current measurement, amperage size and user interface.
