To ensure a consistent power output, JUMO offers thyristor controllers with a current limiting function and optional control algorithms. The thyristor controllers and solid state relays are suitable for resistive and resistive-inductive loads. Ultimately, the maximum temperature that can be reached when heating electrically-powered industrial furnaces depends on the heat sources (e.g. electric arc furnaces, melting furnaces, or furnaces for case hardening). Infrared radiators and high-temperature heating elements made of silicon carbide or molybdenum disilicide can also be controlled.
