Thyro-XD — precision single-phase thyristor power controller, 30 A, 24–500 V, for lamp heaters
Country: USA · Model: Thyro-XD
Thyro-XD, the family's most precise unit, is a single-phase 30 A controller for 24–500 V AC networks holding ±0.25 % for voltage or current. It serves lamp heaters in semiconductor manufacturing, where epitaxy and rapid thermal annealing change temperature within seconds and must repeat cycle after cycle.

Description
The controller also suits industrial processes with strict demands on heating accuracy. The wide 24–500 V input means fewer versions to stock. Power accuracy is ±0.5 % with a phase-angle setpoint from 5 %, and a change in load resistance is detected in steps of 0.25 %, so the unit quickly sees a change in heater temperature and compensates mains fluctuations. Besides TAKT and phase-angle VAR there is a proprietary VT mode with reduced harmonic distortion, and a higher measuring rate lowers ripple and makes control more stable. In a closed temperature loop the unit works together with Impac pyrometers. The housing was made deeper and longer for natural convection, there are no fans, the internal temperature is lower, and according to the maker the same volume holds twice as many channels as earlier designs. Other networks (EtherNet/IP, PROFIBUS, PROFINET, Modbus TCP) connect through the Advanced Bus Module, and setup is done from a modular touch display or a PC.
How to choose
There is one model, 30 A single-phase, so the choice comes down to channel count and interface, and the maker prices it for multi-channel installations. A built-in semiconductor fuse protects the power section, mains frequency is 47–63 Hz, and marking is CE. It is not for furnace power heaters or ROT replacement (Soviet-era single-phase thyristor voltage regulators), which call for Thyro-A for 8–1500 A or Thyro-PX for 16–5000 A.

FAQ
What is the accuracy of the Thyro-XD controller?
±0.25 % for voltage or current and ±0.5 % for power with a phase-angle setpoint from 5 %, and a change in load resistance is detected in steps of 0.25 %.
Does Thyro-XD need a fan?
No, the housing is cooled by natural convection without fans, so units can be packed closely in small cabinets.
How do I connect Thyro-XD to EtherCAT?
EtherCAT and USB-C are built in, and for EtherNet/IP, PROFIBUS, PROFINET or Modbus TCP an Advanced Bus Module is added.
Can Thyro-XD control temperature from a pyrometer?
Yes, the controller works in a closed loop with Impac pyrometers and tracks temperature in real time.
