Utilizing AI adjustment algorithms with curve fitting capabilities, it achieves a smooth and even curve control effect. | |
Control | Utilizing closed-loop technology for silicon-controlled rectifier module triggering control, phase-shifting triggering control method, the output voltage, current, or power is continuously adjustable, featuring constant voltage, constant current, or constant power characteristics; the current loop is the inner loop, and the voltage loop is the outer loop. When sudden load is applied or the load current exceeds the current limiting value, the output current of the voltage regulator remains within the rated current range, ensuring normal operation of both the output and the regulator. Meanwhile, the voltage loop also participates in the adjustment, keeping the output current of the regulator within the rated current range while maintaining constant output current and voltage with ample adjustment leeway; thereby achieving the protection of heating elements from excessive current and voltage surges, ensuring safe and reliable control effects and precision. | |
