The Thyro-A+ is Advanced Energy’s latest addition to its proven Thyro-Family of digital SCR power controller. The new Thyro-A+ has a performance range with rated currents from 16 A up to 280 A and rated voltages from 230 V up to 500 V. Beside its onboard Modbus RTU interface, the Thyro-A+ offers easy fieldbus integration with optional BasicBus Module and available bus protocols, such as Ethernet/IP, EtherCAT, Profibus, Profinet or Modbus TCP/IP.

The optional Thyro-A+ display enables intuitive operation of the SCR power controller. It also allows long-term data recording of process parameters, as well as status messages. With an optional SD card, data and parameter settings can easily be loaded and saved to the SCR power controller. An easy handling is supported by the EasyStart feature for easy Thyro-A+ commissioning. The Thyro-A+ provides all useful customers information on one display either directly at the unit or being mounted on the electrical cabinet door.

• Save space and simplify installation with a compact unit footprint and a DIN-rail mountable design (up to 60 A system rating)
• Precisely regulate power, including load management, for optimal control and energy consumption
• Easily integrate with existing control systems; customize faults, alarms, status, limits, and set points
• Increase process efficiency; optimize load control with five control types and three operating modes
• Scalable PLC/PAC integration for closed-loop control; optional system interface connects up to 8 power controllers to BasicBus Module (Profibus DPV1, Modbus RTU, DeviceNet, CANopen, Profinet, Modbus TCP/IP, EtherNet/IP, EtherCAT)
• Securely separate control and power units and optimize load control; use up to five control methods and three operating modes
• 1-, 2-, or 3-phase versions (2-phase version for 3-phase load without deploying neutral conductor)
