Description
Single-phase 1PX comes in two voltage classes. The 500 V type runs from 230 V −20 %…500 V +10 % and is built for 16, 37, 75, 110, 130, 170, 280, 350, 495, 650, 780, 1000, 1500, 2100, 2900 and 5000 A, the 690 V type from 500 V −20 % to 690 V +10 % for 80–2000 A. 2PX and 3PX serve three-phase loads, and above catalog currents the maker offers water-cooled stacks. A 32-bit processor takes 1.5 million measurements per second at 15-bit resolution, and power accuracy is ±1 %. Besides TAKT and VAR there is sequential voltage control VSC, which cuts distortion and reactive power, plus soft start and stop, with regulation by U, U², I, I² or P. Up to three analog setpoint inputs, three U, I, P actual-value outputs, three alarm relays and load circuit monitoring are on board. The 2.8-inch Thyro-Touch display with logger and SD card speeds up setup and fault analysis, built-in dASM lowers peak demand, and communication runs over PROFIBUS, PROFINET, EtherNet/IP, EtherCAT or Modbus TCP.
How to choose
The model follows from the load current, the 500 or 690 V class and the 1PX, 2PX or 3PX circuit. Housing size and weight grow steeply with current, so check them early when laying out the cabinet. For rectified current in electrolysis there is Thyro-PX DC for 1000–1800 A DC, and for typical heating up to 1500 A Thyro-A is enough.

FAQ
What can replace a ROT-2600E regulator?
A single-phase Thyro-PX 1PX, whose range overlaps regulators from ROT-63 to ROT-2600E (Soviet-era single-phase thyristor voltage regulators). Selection by duty, current, load type and voltage is confirmed by a sales manager.
Which Thyro-PX replaces a 700 V ROT version?
The 690 V type, with a network from 500 V −20 % to 690 V +10 % and currents of 80–2000 A.
Does Thyro-PX work with molybdenum disilicide heaters?
Yes, the MOSI start mode is meant for heaters whose hot resistance is up to 20 times higher than the cold one.
What supply does the Thyro-PX control circuit need?
The control circuit has its own AC or 24 V DC supply, separate from the power section.
