Description
The Watlow ASPYRE AT Smart Power Controller is a flexible, compact and scalable smart SCR power controllers that features multiple advanced firing and control mode algorithms combined with sophisticated diagnostics. It performs closed-loop control on current, voltage and power, which can improve temperature control by quickly responding to voltage sags or other load issues. The ASPYRE AT can connect with a PM PLUS or other Watlow controller via the inter-module bus to receive its set point signal. It is also possible to send the set point signal via a communications protocol such as Modbus RTU. The ASPYRE AT is also available with analog and digital inputs that allow it to receive a signal from other controllers.
Applications that benefit from a smart power controller include applications that demand precise temperature control, applications where system monitoring is important to reduce scrap and applications where there is a high likelilhood the line voltage variation will affect temperature control.
