Load characteristics and matching: It is very important to choose the appropriate load type and power capacity. Thyristor power controllers are suitable for resistive loads and can handle inductive loads too, but capacitive loads may cause problems. Matching of load power is also crucial, too high or too low power capacity will affect equipment efficiency and lifespan .
Voltage and current regulation range : The voltage regulation range of power controllers is limited. The output voltage of common thyristor controllers is generally between 0 and 380V. If the application requires higher voltage, appropriate equipment should be installed .
In addition, overcurrent protection cannot be ignored, although the controller itself is protected, external protection device is still INDISPENSABLE .
Control signals and feedback: Accurate input of control signals is crucial to the regulation effect. If the output signal of the temperature controller is inaccurate or the wiring is incorrect, the controller will be affected. Feedback signals such as sensor damage in the current and voltage monitoring link or poor contact of the feedback line can also affect control effect .
Installation and wiring issues: Wiring is complex. Ensure the correct connection of input power, output load and control signals, and also consider the protection device. Incorrect phase sequence or reversed connection of control signals can cause abnormal operation of the equipment or even shutdown. The installation location should be far away from electromagnetic interference sources, such as transformers or large motors, to prevent control signal distortion and short circuits.
Heat dissipation and environmental conditions: The power controller generates heat when in operation, so good heat dissipation conditions must be ensured. Blockage of the radiator or poor ventilation at the installation location can trigger the overheat protection of the equipment, affecting the work progress. Prolonged use in damp, dusty or corrosive gas environments will damage the internal components .
Overvoltage and overcurrent protection: Appropriate overvoltage and overcurrent protection devices should be installed to ensure that the equipment can protect itself in time in case of abnormality .
Parameter selection and maintenance : When selecting thyristors, consider the rated voltage and current, and leave sufficient safety margin. Regularly maintain equipment to ensure it operates properly .
