Purchasing Guide

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

  • For procurement requirements that require the use of three-phase frequency converters, it is recommended to match the model based on key technical parameters such as motor power range, voltage level, and output frequency accuracy. In industrial scenarios, additional consideration should be given to harmonic suppression function.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. Such suppliers have better stability in typical applications such as fans and pumps.
  • In dusty and humid environments such as food processing or textile machinery, it is recommended to choose a three-phase frequency converter with a protection level of IP65 or above, and verify whether the supplier has provided similar scenario solutions.
  • When purchasing, it is necessary to clarify whether there is a need for built-in PID control or extended functions such as braking units. Different applications such as assembly line speed regulation and heavy machinery start-up have significant differences in dynamic response requirements.
