On May 24th, 2017, TÜV Rheinland Group (hereinafter as TÜV Rheinland) awarded a CB Certificate to the new smart switch, “ L/L+N wiring self adaptive lighting control switch”, developed by Wulian Co., Ltd. (hereinafter as Wulian), which marks the introduction of the product to the global market. Executives from TÜV Rheinland and Wulian, such as Shu Xu, Unit General Manager of Commercial Products of TÜV Rheinland Greater China, and Kun Hou, Unit General Manager of Electrical Accessories, Commercial Products of TÜV Rheinland Greater China, Ren Zhong, Vice President of Wulian, and Jian Zhu, Vice President of Wulian and Vice Chairman of the Board of zigbee alliance, all attended the certification awarding ceremony in Wulian’s headquarter in Nanjing.
With the development of artificial intelligence in recent years, the idea and products of Smart Home are winning the hearts of people. More and more businesses are aiming toward this rising industry, which brings forth intensified competitions between Smart Home products and technologies. As a leading Internet of Things (IoT) equipment and solutions supplier, Wulian continues to deliver innovative products in fields such as IoT sensors, controllers, mobile IoT, cloud computing, and Big Data. Wulian’s Smart Home products and solutions are being used in many key projects around the world, and the company has become one of the major promoters for the IoT Smart Home industry.
Among all the Smart Home products, due to its intelligent control and energy saving features favored by its users, Smart Switch has become one of the key examples. The wiring of the power distribution in switch cartridges can be categorized into L wiring (single Live line wiring) and N+L wiring (Neutral line + Live line wiring) distributions, and different wirings in power distribution can produce intelligent switch products with completely different designs. Although these switches’ functions and structures may seem identical, under different wirings in power distribution, L wiring switch and L+N wiring switch are just not compatible with each other. For this reason, Wulian exclusively developed the “L/L+N wiring self adaptive lighting control switch”, which has the absolute advantage in being compatible to all types of power distribution systems in the world.
Before introducing this new smart switch product to the market, Wulian applied for a Global CB Certificate from TÜV Rheinland. After communications and working together between the core technical teams from both sides, the new smart switch was able to finally pass all the stringent tests based on the IEC 60669 Standards, and meet the technical and quality standards of a technologically innovative product.
When the Smart Home concept is developing in an unstoppable trend, there are more and more unconventional electrical accessories being designed and introduced. Because of the nature of diversity and universality in these products, they have been widely used in all kinds of electrical appliances, electronic products, and power tools. When designing a circuit, two key elements are power control and the signal transmission. However, the variability in products often tends to cause some manufacturers to have misunderstandings on corresponding standards, which is usually accompanied by certain safety concerns, such as electrical shock, burning, explosion, mechanical durability, and structural stability.
In the field of electrical accessories, TÜV Rheinland is not only the world-leading service provider in product safety and certification, but can also provide testing and certification services for all types of new and innovative electrical accessories, such as household plugs/sockets, household converters, household wire reels, industrial plugs/sockets/connectors, connectors for electric vehicles, household wall switches, timers, and remote controls, based on the BQB, CE-RED, zigbee, FCC, IC, and TELEC standards. The internationally recognized test labels from TÜV Rheinland will help its clients in complying the regulations in different countries, such as Europe, the United States, Middle East, Brazil, Australia, Chile, Argentina, South Africa, Indonesia, India, Japan, and Israel, and thus successfully entering the international markets.
