Thyristor Switch for General Heating Applications, Supports Load Currents Up to 350 A

Efficient yet powerful, the Thyro-S power controller is Advanced Energy’s most compact digital thyristor switch.

  • Compact footprint with multiple operating voltages and current ranges
  • Load monitoring, alarm relays, and power measurement
  • Analog and digital communications with optional fieldbus communication options


The highly efficient Thyro-S® thyristor switch delivers accurate, reliable, switch-free performance. Connect to bus systems, use as a stand-alone unit, or use in combination with all established two-point controllers — PLCs or computer systems. With simple mounting, minimal space requirements, quick commissioning, and safe operation, Thyro-S switches are seamlessly integrated into various applications. Status LEDs provide a quick overview of system status and load percentage.


  • Easily install with compact unit footprint and simplified mounting design
  • Reduce peaks and perturbations via the optional Thyro-Power Manager
  • Customize faults, alarms, status, limits, and set points for easy integration to existing control systems
  • Secure isolation between control and power sections for safe operation
  • Optimize load control with up to five control methods


  • Designed for transformer loads
  • Scalable PLC/PAC integration for closed-loop, thermal process control; optional system interface connection of up to eight power controllers to bus module or BasicBus Module (Profibus DPV1,  CANopen, PROFINET, Modbus TCP/IP, EtherNet/IP, EtherCAT)
  • DIN-rail mounting up to 60 A systems
  • USB interface for Thyro-Tool software
  • 1-, 2-, or 3-phase versions (2-phase version for 3-phase load without deploying neutral conductor)
