To ensure safety and market access, the controller must adhere to international electronics standards. For the North American market, UL 60950-1 or UL 62368-1 certification is critical for electrical safety. For European markets, the CE mark is mandatory, specifically compliance with the EMC Directive (2014/30/EU) to ensure the controller does not interfere with other electronic devices. Furthermore, ensure the product is RoHS compliant, guaranteeing it is free from hazardous substances like lead and mercury, which is a standard requirement for modern sustainable procurement.
