A power regulator is a panel-mounted power adjustment unit that uses a thyristor and its trigger control circuit to adjust the load power. The thyristor, which plays a very important role in electronic equipment, is widely used in various production departments and is becoming a An indispensable equipment for automation and efficiency.
The use of thyristors is obviously popular in new temperature control. However, it has different names in China, such as thyristor regulator, thyristor regulator, thyristor controller, thyristor controller, and thyristor voltage regulator. , thyristor voltage regulator, thyristor power regulator, thyristor power regulator, voltage regulator, power regulator, thyristor AC power controller, thyristor AC power controller, power regulator, power controller, Voltage regulator, voltage controller, etc. The name is power regulator, which is also one of the more common names in China.
Introducing an economical and reliable power regulator. The 3-phase thyristor power regulator uses a digital circuit to trigger the thyristor to complete voltage regulation and power regulation. The voltage regulation adopts the phase-shift control method, and the power regulation has a fixed period adjustment. There are two methods of power adjustment and variable cycle power adjustment. The control board has a phase-locked loop synchronization circuit, automatic phase identification, phase loss maintenance, power-on slow start, slow shutdown, radiator over-temperature detection, constant current output, current limit, Over-current maintenance, serial operating status indication and other functions. There are two ways to trigger the control panel: direct triggering of the thyristor module and triggering of the phase-shifted solid-state relay. Features of the control panel: 12-bit A\/D, output linearization The degree is high and the output starting control point is low.
The 3-phase power regulator is composed of a trigger plate, a special radiator, a fan, a casing, etc. The central part uses a 0 control panel and a German Siemencon thyristor module; the heat dissipation system uses a high-efficiency heat dissipation and low-noise fan. The whole machine is equipped with a control panel All functions. The current capacity of the whole machine has 7 levels from 40A to 800A.
The power regulator is used with an intelligent PID regulator or PLC with 0-5V, 4-20mA; it is mainly used for heating control of industrial electric furnaces and soft-start energy-saving operation control of large fans and water pumps. The load type can be 3-phase resistive load , 3-phase inductive load and 3-phase transformer load; 3-phase load can be center grounded load, center ungrounded load, inner triangular load and outer triangular load.
