The LQ36P series three-phase thyristor AC regulator is a power controller that integrates phase shift voltage regulation and power regulation. The regulator has various protection functions such as overcurrent, phase loss, short circuit, wire breakage, overheating, and LED working status indication.
It can be widely used in various fields of industry, such as resistive loads, inductive loads, transformer primary side, etc. The main applications are as follows:
◇ Temperature control using nickel chromium, iron chromium aluminum, far-infrared heating elements, silicon molybdenum rods, silicon carbon rods, etc. as heating elements.
◇ Temperature control of salt bath furnaces, power frequency induction furnaces, quenching furnaces, and molten glass.
◇ Rectifier transformer and furnace transformer primary side control.
◇ Stepless smooth adjustment of voltage, current, power, etc.
◇ Constant voltage, constant current, and constant power control.
