Variable Frequency Drive 380V 7.5KW-450KW

Designed specifically for industrial fans (such as workshop ventilation fans, boiler induced draft fans, and dust removal fans), it core addresses the low efficiency pain point of traditional fans, which is "fixed speed at power frequency + damper adjustment". It supports precise speed regulation at 0.01Hz level and can dynamically match the air volume based on the flow of people in the workshop, boiler load and dust concentration. For instance, when the boiler induced draft fan operates at a reduced speed under low load, the electricity saving rate can reach 20% to 40%, and the investment can be recovered within one year. The soft-start and soft-stop function keeps the starting current within 1.2 times the rated current, preventing the fan blades from breaking due to instantaneous impact and extending the equipment's service life by 3 to 5 times. The built-in PID regulator can be linked with the CO₂ sensor and dust detector in the workshop to achieve closed-loop automatic control of a…
