Description
AIJK Series Thyristor Triggers
The AIJK series thyristor triggers are intelligent three-phase phase-shift triggers and frequency zero-crossing dual-purpose trigger controllers developed using microcontroller technology. They feature high control accuracy, strong stability, and comprehensive functions. This series is widely applicable to various industrial electric furnaces and electric heating equipment, and can be matched with various types of loads such as resistance wires, silicon carbide rods, silicon molybdenum rods powered by transformer step-down, and tungsten wires. It can also be used for motor soft starting and inductive load control.
The equipment adopts a fully opto-isolated design, possessing high reliability and anti-interference capabilities. Through intelligent power correction technology, it achieves a linear correspondence between output power and input signal, meeting the precise temperature control and stable operation requirements of industrial heating equipment.
Product Features
- Multi-Signal Compatible Input
