Lithium-Ion Batteries Rechargeable lithium-ion (“li-ion”) batteries (comprised of cells in which lithium ions move from a negative electrode through an electrolyte to a positive electrode during discharge—and the other way around when charging) were first described conceptually in the 1970s. Following initial prototype development in the 1980s, li-ion batteries became ...

Surge Protective Devices (SPDs) are designed to limit damage from electrical surges. Surges happen extremely fast and may pass through electrical breakers before the breaker can trip. This is because breakers are designed for over current protection, and not surges. Electrical surges can become powerful enough to damage or kill downline products that include electronics. Even if downline products ...

High—frequency heat sealing hf welding equipment is the first choice of plastic heat sealing equipment. The principle is different from plastic welding machine with conduction of heat because it is the use of high-frequency electric field polar molecules to produce plastic torsion friction heat, and thus to achieve the purpose of welding. The welding temperature is uniform in the outside ...

How poe works Many Internet connected devices, such as IP cameras, VoIP phones, WIFI radios, and Ip access card readers, use Power over Ethernet. A single network cable transmits data and power to the device, making installation simple. Data uses one set of wires, and power uses another set of wires in a network cable. Devices that plug power into certain wire pairs in an Ethernet cable are ...

One of the most important problems in the operation of electronic equipment in the residential blocks is the overvoltages. Direct damages of overvoltages lead to a loss of value (technical cost), whereas indirect damages result in the loss of opportunity (social cost). The assessment of these costs is of particular importance especially to countries, which are hampered by the current financial ...
