Description
The modular approach is needed with water cooling, several power cabinets or control placed far from the power section. The control board matches series Thyro-PX units, with TAKT, VAR and VSC, soft start and stop, regulation by U, U², I, I² and P, and ±0.5 % accuracy for voltage or current and ±1 % for power. MOSI start handles heaters with a hot-to-cold resistance ratio of up to 20. Firing pulses travel over optical fiber through E-O-E electro-optical boards, isolating the power circuits from control and keeping interference out. Circuits cover W1C–W3C on AC and B12/B18 on DC, and one controller can run several single-phase loads independently. The controller is a 75×284×204 mm module drawing 50 W and rated up to 40 °C, it is set up from a modular touch display or a PC and talks via EtherNet/IP, EtherCAT, PROFIBUS, PROFINET and Modbus TCP.
How to choose
There is no ready catalog number, the system is configured with the maker for the circuit, voltage and number of zones. With power and control separated, stacks and controller are replaced independently, and control cabinets can stand in a clean room far from the furnace. If a series controller up to 5000 A will do, Thyro-PX is simpler, and for electrolysis rectification there is the ready-made Thyro-PX DC.

FAQ
What can replace a high-power thyristor station rated at thousands of amperes?
For such installations Thyro-PX Modular is engineered together with the maker, with water-cooled stacks up to 690 V AC or 900 V DC.
Is Thyro-PX Modular suitable for arc furnaces?
Yes, the maker lists arc furnaces among its applications, along with transformer-fed electric furnaces for glass, metal and ceramics and the supply of hydrogen electrolyzers.
Why does Thyro-PX Modular use optical fiber?
Firing pulses are transmitted over optical fiber through E-O-E boards, so the power section is isolated from the controller and interference does not get into the control.
How many loads can one Thyro-PX Modular controller handle?
One controller runs several single-phase loads independently, working as a multi-zone controller. The module itself measures 75×284×204 mm and draws 50 W.
