Purchasing Guide

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

  • For procurement requirements that require the use of isolators, it is recommended to first clarify key parameters such as input/output voltage range, isolation withstand voltage value, and signal transmission rate. Industrial automation scenarios typically require an isolation strength of 10kV or higher.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. For example, in the medical equipment field, suppliers need to verify their actual cases in EMC protection.
  • There are significant differences in the performance requirements for isolators in different scenarios. The power system focuses on high isolation voltage, while communication equipment pays more attention to low signal delay. Before procurement, specific application scenarios need to be evaluated.
  • In industrial control systems, it is recommended to choose isolator models that support wide temperature operation (-40 ℃~85 ℃) and have passed long-term reliability testing, while also paying attention to the supplier's project experience in the energy industry.
