Latching Relay & Geography Requirements
Relay as an electrical control device, when the input quantity (excitation quantity) changes to meet the specified requirements, an electrical appliance that causes the controlled quantity to undergo a predetermined step change in the electrical output circuit. The application scenarios are very wide, such as remote control, Telemetry, communication, automatic control, mechatronics, new energy vehicles, smart cities, etc.
There is an old Chinese saying: A radish has a pit. It means that different characteristics can meet different needs. As far as relays are concerned, different countries and regions have different requirements for relay performance, appearance, parameters, certification and so on. Then let us learn more about relay certification based on the different requirements for relay certification in different countries and regions. So what are the main relay certifications? What market are they mainly adapted to? Relay certification generally includes: UL certification, CE certification, TUV certification and so on. Next, we will take a look:
UL is the abbreviation of Underwriter Laboratories Inc. in English. UL Safety Testing Institute is the most authoritative in the United States, and it is also a larger private organization engaged in safety testing and appraisal. In European markets, such as Germany and Italy, there are cases where UL certification is required.
The CE mark is a safety certification mark and is regarded as a passport for manufacturers to open and enter the European market. All products affixed with the "CE" mark can be sold in the EU member states without meeting the requirements of each member state, thus realizing the free circulation of goods within the EU member states. Therefore, CE certification is required by most European countries, such as Germany, Austria, France, Italy, Sweden, Lithuania, Russia, etc.
The TUV mark is a safety certification mark customized by German TUV for component products, and is widely accepted in Germany and Europe. At the same time, companies can apply for CB certificates in combination when applying for the TUV mark, thereby obtaining certificates from other countries through conversion. International Electrotechnical Commission's certification IEC-620555-31 subsidiary certification-UC3 certification comes from the TUV laboratory. Everyone knows the importance of UC3 certification to relays, so India, New Zealand, Australia, Pakistan, and many European countries, such as Germany, France, Lithuania, Russia, etc., all attach great importance to UC3 certification.
Different countries and regions have different certifications for relays. Again, in the context of increasingly complex and strict market requirements, we are confident and able to bring more powerful relays to every market!
