Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • When selecting frequency converters for supply, it is recommended that enterprises match key technical parameters such as output voltage and frequency regulation accuracy based on load type and motor power range. There is a significant difference in dynamic response requirements between industrial production lines and HVAC systems.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. In the chemical industry, special attention should be paid to industry application cases of explosion-proof model suppliers.
  • When purchasing frequency converters, it is usually necessary to pay special attention to the heat dissipation design and protection level. For applications in harsh environments such as mining machinery, the protection standard should reach IP65 or above.
  • For high torque application scenarios in the metallurgical industry, it is recommended to choose models with an instantaneous overload capacity of over 150%, while verifying the supplier's equipment operation data in the heavy industry field.
