Product Description
ST30 three-phase rectification thyristor trigger regulator board adopts 32-bit industrial grade high-performance microprocessor, high digital precision quality design, support network remote control and on-site control mode. The fuzzy-PID parameter is open-ended, which integrates open-loop voltage regulation, closed-loop constant voltage and constant current in one, to control the thyristor to achieve constant voltage current limiting or constant current voltage limiting. The fault alarm and interface parameters are displayed on the LED digital tube menu, and parameters are automatically stored after setting. The control board (regulator) has the functions such as phase loss protection, power-on soft start, soft shutdown, constant current output, constant voltage output, overvoltage protection, overcurrent protection, short circuit protection, and working status indication. It has three-phase full-control bridge rectification, double anti-star rectification and thyristor anti-parallel AC triggering mode, which can trigger thyristor below 1000A, suitable for resistive load and, inductive load, capacitive load, transformer primary side and other types of loads which adjust by voltage and current regulation in various fields of industry. It has been widely used in electrolytic and plating devices, battery charge and discharge devices, three-phase thyristor power supply devices, electric heating temperature control devices, arc discharge control and other equipment.
This trigger board adopts industrial-grade high-performance microprocessor, which continues to lead the innovation of core control algorithms and software technology in the industry. The structure of the control software package and the processing speed of the single-chip microcomputer ensures all the adjustment of the control loops to be finished during transform (conversion) time of the six thyristor bridges in the main circuit, so that the voltage and current loop sampling time can be less than 3.33mS (50HZ power supply) or 2.77mS (60HZ power supply) for superior performance.
ST30 three-phase digital rectification thyristor trigger regulator has a variety selections of given control signal, and supports analog input automatic control modes such as 0-5Vdc, 0-10Vdc, 0-10mA, 4-20mA, etc., and can also controlled by potentiometers (10K 2W) Manually. Flexible and convenient, with reliable and stable performance, strong anti-interference ability, unique anti-interference measures, normal operation in harsh interference environment, complete control panel self-diagnosis and load operation protection. It is also with power failure protection, over-voltage protection, overload protection, phase failure protection, etc. Therefore, regardless of the external or internal interference types and fault signals, the performance of the control board is safer and more reliable due to the above-mentioned protection functions. The outputs are completely isolated and has a wide application range. It has complete fault detection and alarm indication and protection function. All parameters of ST30 are digital, no temperature drift changes which improves the adjustment accuracy and power utilization efficiency.
