IP 66, IP68 คืออะไร IP - Ingress Protection Ratings Is a standard used to measure the ability to protect the things inside of electronic devices. In the case of CCTV It is an indication of the ability of the camera body to protect the internal circuit from the external environment. Which translates as being durable in the use of the camera This standard was developed by the European Commission for Electro Technical Standardization (CENELEC) (NEMA IEC 60529 Degrees of Protection Provided by Enclosures - IP Code). Solid defense ability And the second principle is the ability to prevent liquid The standard display format is IPXX, which XX is…

RoHS standard RoHS environmental standards When choosing to view electronic products or in the Datasheet of various electronic devices Would have seen a circular symbol With the letter "Pb" and expected with a oblique line Or have written "RoHS Compliant" or will write "Pb-Free", "Green" or whatever That means that those devices Passed the requirements called "RoHS" (the symbol of each brand is different Because there is no official symbol What is RoHS? RoHS Stands for Restriction of Hazardous Substances Is the preparation for 2002/95 / EC of the European Union (EU) on the issue of the use of hazardous materials in the use of equipment and electrical…

Will be widespread in Europe and Asia, but in America it is not as excited as it should be Because if talking about the American system, it will go to TQM, Balanced…

UL 94 flame classifications There are two types of pre-selection test programs conducted on plastic materials to measure flammability characteristics. The first determines the material's tendency either to extinguish or to spread the flame once the specimen has been ignited. The first program is described in UL 94 which is now harmonized with IEC 60707, 60695-11-10 and 60695-11-20 and ISO 9772 and 9773. The second test program measures the ignition resistance of the plastic to electrical ignition sources. The material's resistance to ignition and surface tracking characteristics is described in UL 746A, which is similar to the test procedures described in IEC 60112, 60695 and 60950. UL 94…

Types of wires AWG Types of wires The power cord is divided into two major types: Cables for low-voltage lights and for high-voltage lighting in this article will discuss the wires used in buildings, which are classified as low voltage cables. For Thailand Low voltage cables must be in accordance with TIS 11-2531 or TIS-11-2531 standards. In accordance with standards, low voltage cables will have many sizes. (Cross-sectional area) from small to large Which can withstand voltage from 300 volts to 750 volts. Power cables according to TIS 11-2531 standards will be divided into categories according to size Voltage resistance and usage are as follows              1 Ivy line…
