SCR Power Controller

SCR Power Controller Knowledge Card

An SCR (thyristor) power controller regulates the power delivered to electric heating loads and holds the process temperature steady. It suits duties that need continuous power control, zone-by-zone temperature control and long-term stable operation.

What it solves

• Unstable heating power and drifting furnace temperature.
• Insufficient accuracy where several temperature zones must be controlled.
• Constant power, constant voltage, constant current or communication-based control.

Typical applications

Industrial furnaces, single-crystal and polycrystalline silicon furnaces, diffusion furnaces, sintering and vacuum furnaces, glass and glass fibre, metallurgy and heat treatment.

Selection parameters

Input voltage, load type, rated current, rated power, control method, number of temperature zones, communication interface, installation environment and cooling conditions.
