Watlow ASPYRE® AT Power Controllers

Modular and Scalable Power Controllers Enable Increased 

Throughput and Yield While Reducing System Complexity

The ASPYRE® AT is a family of flexible, compact and scalable smart

SCR power controllers. It features multiple advanced firing and control

mode algorithms combined with sophisticated diagnostics.

The ASPYRE AT integrates easily with EZ-ZONE® RM, PM PLUS® and

RMA PLUS™ controllers as part of a Watlow® ecosystem solution.

Features and Benefits

Key component of a Watlow ecosystem solution

• Integrates with EZ-ZONE® RM, RMA PLUS™ and PM PLUS®

controllers for a complete solution including Modbus® TCP,

EtherNet/IP™, or EtherCAT® communication

• Eliminates discrete wiring between temperature controllers

and power controllers for each heater through the highspeed

backplane interface with Watlow controllers

• Enables data collection and diagnostics from the power controllers

• Customizes for your application with programmable

function blocks including logic, math, compare and more

High accuracy current and voltage measurement

• Characterizes process performance

• Supports comparing (fingerprinting) equipment operation

Integrated, scalable solution

• Allows connection from the temperature control system at

one point communicating with up to 16 power controllers

• Offers greater than 60% reduction in wiring footprint and

costs compared to other multi-zone systems

• Eliminates need for current transformer and associated

wiring with integrated current measurement

Industry-leading design and serviceability

• Offers a robust SCR design to meet a rugged industrial

environment’s high quality and reliability needs

• Enables fast troubleshooting by providing helpful thermal

system diagnostics

100KA short circuit current rating (SCCR)

• Enables greater protection in the event of a short circuit

c-UL® 508 Listed

• Shortens project schedules, agency testing and expenses

Closed-loop control on: Voltage, current or power

• Compensates for line voltage variations and thermal

component tolerances (e.g. heater wattage, insulation

variation, etc.)

Load firing modes: Zero-cross, burst fire, phase angle,

soft start

• Handles a wide range of load types

• Protects and extends the life of connected loads

Open heater and shorted SCR indication

• Minimizes production downtime with easy to understand,

intelligent, troubleshooting diagnostics

Integrated USB for configuration

• Easily and safely program configuration settings with

electronics powered through USB connection

• Eliminates a user from having to work in a high voltage,

hazardous environment. High voltage to controller or

system panel can be turned off while setting controller

configuration

Heater bakeout

• Protects heater on startup

• Eliminates labor and time associated with checking for wet

heaters

Cooling options

• Integrates DIN-rail mountable heat sink option for

simplifying implementation

• Offers base plate option for flexibility in removing heat from

the electrical box
