Active Bridge Rectifiers Reduce Heat Dissipation within PoE Security Cameras

Ryan Huff - PoE Applications Engineer Oct 1st 2013
Introduction Power over Ethernet (PoE) has been embraced by the video surveillance industry as a solution to an age-old problem: complicated cabling. For instance, a basic, traditional fixed-view security camera requires two cables: one for power (10W to 15W from a 24V AC or 12V DC), and a separate, coax cable for the video ...

LTPoE++ PSE & PD Controllers - Video Product Brief

Chris Gobok - Product Marketing Engineer Sep 21st 2012
Power over Ethernet, or PoE, is an increasingly popular way to deliver both power and data over existing Ethernet cable, thus freeing applications from the constraint of AC-power proximity. As the number PoE solutions has grown so has the applications’ appetite for power. A new proprietary standard, LTPoE++™, satisfies ...

High Efficiency PoE++ PD Controllers Provide up to 90W Delivered Power

Aug 27th 2012
MILPITAS, CA – August 27, 2012 – Linear Technology Corporation introduces the LT4275, LTPoE++™, PoE+ and PoE-compliant powered device (PD) interface controllers for applications requiring up to 90W of delivered power. PoE+ limits the maximum PD power delivery to 25.5W, which is insufficient to power today’s new class ...
