Thyro-A+ — digital thyristor power controller with display, 1/2/3 phases, 16–650 A, 230–500 V
Country: USA · Model: Thyro-A+
Thyro-A+ extends the Thyro-A line to 16–650 A at 230–500 V, with more precise measurement, a display and setup without potentiometers. It controls heaters in heating, melting, drying and forming, and the single-phase 1A version replaces single-phase ROT thyristor regulators (Soviet-era single-phase thyristor voltage regulators).

Description
The 1A version runs full-cycle TAKT, phase-angle VAR on every half-wave, fast half-cycle QTM for resistive loads without a transformer, combined VT and SWITCH with soft start and stop. 2A and 3A handle three-phase loads, 2A in the economical circuit without neutral. The ±1.5 % error is the same for voltage and current, while Thyro-A is coarser on voltage. Heaters whose resistance changes up to 6 times during heating are fine, and a current-limited start removes magnetizing inrush on transformers. Parameters come from the optional display or Thyro-Tool Pro, EasyStart shortens commissioning, and an SD card stores a parameter set and moves it to another unit. BasicBusModule puts up to 8 controllers on one bus and adds dASM mains load optimization, which coordinates switching and cuts consumption peaks. A semiconductor fuse protects the power section, and units up to 60 A mount on a DIN rail.
How to choose
Size the current with a margin over the heater current, and note that sources disagree (the maker's page gives 16–650 A, an older datasheet only 16–280 A), so confirm ratings above 280 A before ordering. Mains tolerance is −57 %…+10 % of the 230–500 V rating. Thyro-A covers 8–1500 A without a display, and Thyro-PX goes up to 5000 A and 1000 V.

FAQ
What can replace a ROT-630M regulator?
A single-phase Thyro-A+ 1A, which fits instead of regulators from ROT-63 to ROT-630M where ±1.5 % accuracy and a digital link are needed. Selection by duty, current and voltage is confirmed by a sales manager.
How does Thyro-A+ differ from Thyro-A?
It measures more precisely, ±1.5 % for voltage and current, and adds an optional display, setup without potentiometers, an SD card for parameters and SWITCH mode with soft start.
How do I connect Thyro-A+ to PROFINET?
Through BasicBusModule, which puts up to 8 controllers on one bus and also supports PROFIBUS DPV1, EtherNet/IP, Modbus TCP, EtherCAT and CANopen. AOP profiles are available for Rockwell Studio 5000.
Can a transformer be fed through Thyro-A+?
Yes, the load can be resistive or a transformer, and the built-in current-limited start eliminates magnetizing inrush.
