Watlow ASPYRE® DT Power Controllers

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

Watlow’s new ASPYRE® DT 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 DT models

available include sizes from 35 to 2100 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 DT 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.
