Frequently Asked Questions (FAQ)
It seems that models of thyristor differs depending on the type of heater, but what are the types of heaters?
They are classified according to the temperature characteristic of electrical resistance. Nichrome type has a small resistance temperature coefficient, pure metal type and molybdenum disilicide type have a large resistance temperature coefficient,
There are three types of silicon carbide (SiC) whose temperature coefficient of resistance shows U-shaped characteristic. The thyristors are suitable for voltage, current, and power feedback types, respectively.
