Unmanaged POE Industrial Switches
PoE power supply switch refers to a switch that can provide network power supply for remote powered terminals through a network cable. It includes two functions: network switch and PoE power supply. It is a relatively common power supply device in PoE power supply systems.
PoE power supply switch refers to a switch that can provide network power supply to remote powered terminals through a network cable. It includes two functions: network switch and PoE power supply. It is a relatively common power supply device in PoE power supply systems. The port supports an output power of 15.4W, which conforms to According to the IEEE802.3af standard, the port supports an output power of 30W and conforms to the IEEE802.3at standard. It supplies power to standard POE terminal equipment through network cable power supply, eliminating the need for additional power wiring. A POE switch conforming to the IEEE802.3aT standard, the port output power can reach 15-60W. In layman's terms, a POE power supply switch is a switch that supports network cable power supply, which can not only realize the data transmission function of ordinary switches but also supply power to network terminals at the same time .

The report said that China, Japan, India, Australia, and South Korea in the Asia-Pacific region will have a total demand of 3.3 GW in 2011. China and Japan benefited from the support of the New Deal and their demand growth was the leading factor.
“The policy structure of major markets in the Asia-Pacific region is undergoing profound changes. China, India and Australia have started to build grid-connected photovoltaic power generation markets. Japan and South Korea are facing policy changes in order to revive domestic demand in the coming years.†Road.
Solarbuzz estimates that the scale of China's PV market can expand by up to 174% over the previous year in 2011, thanks to the national and provincial construction plans. China is a major producer of photovoltaic products and its output accounts for about half of the world's output. However, the domestic photovoltaic power generation market is still in its infancy.
Solarbuzz President Craig Stevens said that both China and India have several projects to be built in Jiwa, and their market growth is expected to rise. "But the biggest challenge for these projects right now is to safeguard financing in a constantly changing policy and regulatory environment."
"If these policies succeed in promoting the expected growth in the Asia-Pacific region, they will help reduce the impact of the European market's reduction of subsidies," he said.
According to the report, Japan’s newly installed PV capacity this year will be at least 1.29 GW, an increase of about 35% year-on-year. India’s newly installed capacity may also double year-on-year. As of June, the data show that the country will complete construction by 2013. A total of 1.5GW of grid-connected photovoltaic projects; the new plan of South Korea plans to add 1.2GW of photovoltaic capacity in the next five years.
POE (Power Over Ethernet) means that without any changes to the existing Ethernet Cat.5 cabling infrastructure, it is used for some IP-based terminals (such as IP phones, wireless LAN access points AP, network Cameras, etc.) can provide DC power supply technology for such devices while transmitting data signals. The POE technology can ensure the normal operation of the existing network while ensuring the safety of the existing structured cabling, minimizing costs. POE is also known as a power supply system based on local area network (POL, Power over LAN) or Active Ethernet (Active Ethernet), sometimes also referred to as Power over Ethernet for short. This is the use of existing standard Ethernet transmission cables to transmit data and data at the same time. The latest standard specification of electric power, and maintains compatibility with existing Ethernet systems and users. The IEEE 802.3af standard is a new standard based on the POE of the Ethernet power supply system. It adds related standards for direct power supply through the network cable on the basis of IEEE 802.3. It is an extension of the existing Ethernet standard and the first international standard for power distribution. standard
Solarbuzz, the industry watchdog, is expected to report rapid development of the Asia-Pacific photovoltaic market. By 2015, it will provide 26% of global demand, which is a significant increase from 11% in 2010.
