The power controller is a rack-mounted power adjustment unit that uses thyristors (also known as silicon-controlled rectifiers) and their triggering control circuits to regulate load power. Thyristors, also known as silicon-controlled rectifiers (SCR), which play an important role in electronic equipment, are widely used in various industrial sectors and are becoming indispensable components in automation.
In recent temperature control applications, the use of thyristors has become increasingly widespread. However, in China, they are known by various names, such as thyristor controller, silicon controlled rectifier (SCR) controller, thyristor control instrument, SCR control instrument, thyristor voltage regulator, SCR voltage regulator, thyristor power regulator, SCR power regulator, voltage regulator, power regulator, thyristor AC power control instrument, SCR AC power control instrument, power adjuster, power control instrument, voltage adjuster, and voltage control instrument, among others. The term "power adjuster" is one of the more common names used domestically.

PID regulator: Proportional-Integral-Derivative regulator, an automatic control device that adjusts the output by comparing the actual measured value with the set value, widely used in industrial process control (such as temperature, pressure, flow control of electric furnaces).
PLC: Programmable Logic Controller, a digital operation controller with microprocessor, used for logical control and sequence control of industrial equipment, and can realize linkage control with power regulators.
Neutral-grounded/ungrounded load: A classification of three-phase load connection modes related to whether the neutral point of the load is connected to the ground, which affects the stability and fault handling mode of the power supply system.
Delta load (inner/outer): A load connection mode where three load units are connected end-to-end to form a "delta" shape; "inner" and "outer" usually refer to the relative connection relationship between the load and the main circuit, which needs to be matched with the power regulator's output mode.
