SPECIFICATION SHEET 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. • Heat treatment • Glass industry • Power generation Heater bakeout • Protects heater on start up • Eliminates labor and time associated with checking for wet heaters Integrated semiconductor fusing, current transformer and user interface • Saves installation time and eases setup and commissioning • Delivers a user-friendly, intuitive interface Industry-leading design and serviceability • Offers a robust SCR design to meet a rugged industrial environment's high quality and reliability needs • Provides quick and easy access to maintain and service fuses and individual legs in minimal time • Enables fast troubleshooting by providing helpful thermal system diagnostics Comprehensive power controller range • Provides wide range of options from simple single-phase to complex three-phase loads to 690V 100KA short circuit current rating (SCCR) • Minimizes damage in the event of a short circuit c-UL® 508 Listed • Shortens project schedules, agency testing and expenses Control modes: contactor, voltage, current or power • Satisfies a wide range of demanding thermal applications Load firing modes: zero-cross, burst fire, phase angle, soft start, half-cycle, single-cycle, delayed triggering • Handles a wide range of load types including nichrome, medium and long waveform infrared lamps, moly (Kanthal® Super), transformers, silicon carbide, UV lamps and tungsten • Protects and extends the life of connected loads
