Recently, Toshiba announced the development of an AC/DC off-line LED controller IC for single-stage conversion PFCs for LED lamps and lighting equipment. The product is currently sampling and will be available in July this year.
The new product is an isolated flyback LED power controller for demanding design standards: support for thyristor dimming; active PFC with single-stage converter, improved PFC and reduced peripherals; no optocoupler And a detector for secondary secondary LED current control of the transformer. The standard 120-220VAC power factor (PF) exceeds 0.8-0.9, and the LED output current accuracy is +/-5%.

What is the Patch Panel? Why is the good choice for your Server Center and Data Center?
A patch panel is a steel panel with a number of ports helps organize a group of cables. Each of those ports includes a wire that goes to a different location. Patch panel could be small size with 2 ports, or very large size with hundreds of ports. They could also be installation for fiber optic cables, RJ45 cables, CAT5E / CAT6 / CAT6A/ CAT7 / CAT8 Ethernet cables, and many others.
