The three-zone thyristor-based control panel is designed to precisely regulate power in strand annealing furnaces with a capacity of up to 120 kW. Accurate temperature profiling over the strand’s length during the annealing process is made possible by the separate control of voltage, current, or power that each zone offers.

These panels reduce power fluctuations, increase energy efficiency, and ensure consistent thermal performance across all zones by utilising cutting-edge thyristor technology. They are ideal for continuous strand annealing applications that require high precision and repeatability, as they feature inbuilt closed-loop temperature feedback that provides uniform heating for both resistive and inductive loads.
