Thyristor power control panels
We design and build thyristor power control panels for precise power control in furnaces, heaters and thermal processes. With phase-angle and zero-crossing control, RS485 Modbus RTU communication and current up to 600 A per channel, we size the panel to your process. Sales and quotes from Ankara-based AOM, nationwide across Turkey.
- Proportional power up to 600 A per channel
- 4–10 channels per panel, up to 132 channels from a single unit
- Phase-angle and zero-crossing cycle control, RMS feedback
- Monitoring and adjustment from PLC/SCADA via RS485 Modbus RTU
- At least 40%+ energy savings measured in AOM projects*
* The lowest savings measured in AOM projects is 40%; the exact figure varies by process, heater type and existing control method.
What we do
Proportional power up to 600 A per channel; 4–10 channels per panel, up to 132 channels total from a single unit. Thyristor protection with semiconductor fuses, fan cooling, digital display.
Phase-angle control for heaters with low thermal mass and sudden current draw; zero-crossing cycle control for lower harmonics/EMI in high-thermal-mass furnaces and molds.
Closed loop with a thermocouple/PT100 temperature sensor, a PID controller or PLC, and the thyristor unit's RMS feedback: deviations are corrected instantly and the setpoint is held.
Current, voltage and power of every channel are read into a PLC or SCADA via RS485 Modbus RTU; consumption is monitored per line.
We convert contactor on/off control or electric hot-oil heating systems to be driven by an AOM thyristor panel; temperature is more stable and heating elements last longer.

Frequently asked questions
With contactor on/off control the heater runs at full power, overshoots the setpoint, switches off and waits to cool; thyristor control adjusts power continuously and proportionally between 0–100%. The lowest energy saving measured in AOM projects is 40%; the exact figure depends on the process, heater type and existing control method. There's also no wearing contact, so maintenance cost is lower.
Phase-angle control suits heaters with low thermal mass and sudden current draw (e.g. infrared lamps); zero-crossing cycle control, which reflects lower harmonics and EMI to the grid, suits high-thermal-mass furnaces and molds. We make the final choice together based on your process.
Yes. We convert your contactor on/off panel or electric hot-oil heating system to be driven by an AOM thyristor panel.
Yes. Our panels communicate via RS485 Modbus RTU; you can read the current, voltage and power of each channel from your PLC or SCADA.
