Product discontinued - has been replaced by PTU-58R-EXT/PoE
PTU-8R-EXT / PoE is patch-panel for Ethernet network integrated with high-end surge protection, containing 3 levels of protection. It uses automatic fuses MOSFET 1us response time, acting as a quick and effective decoupling element, creating a barrier during the surge. This gives a very high level of protection from surges and groung loop. Extreme Series is recommended for Ethernet protecting , where network devices (IP cameras) on masts or poles and roofs and are exposed to direct lightning.
The device is built on the basis of 2 removable 4-channel modules arranged in rack patch-panel. This ensures the seamless exchange in case of failure or the use of another series of modules, in order to adapt to the needs of the system. Free space for 2 modules can be used depending on demand modules Eco or Pro Series.
Housing mounted in the rack has a special holes and tabs for restraining LAN wire using band clips. Further holes allow the use of band clips for each cable, which increases the mechanical strength.
In assumption panel is intended for installation in 19" rack, but specially made holes allow mounting it on the wall. After installing the optional cover panel is protected against mechanical damage and accumulation of dirt.

Example of use
Protection is to suppress the high power shock pulse, resulting in relation to ground (gas tubes) and pulses induced between pairs of UTP wires during lightning. These pulses have a destructive effect on the Ethernet interface drivers, despite the use of galvanic insulation used on the hardware layer. PTU-8R-PRO / PoE is specially designed for powering CCTV from PoE switches.
To powering it are used 4,5 and 7,8 pins, which are connected together in order to increase the current flowing through the protection system. Due to the limited power decoupling resistors, the maximum power to the equipment should not exceed 30W at 48V. Decoupling resistors protect the safety components from damage in the event of an overvoltage a longer time and allow for gradation of security. The device should not be used to install Category 6.

The differences between the series PRO and EXTREME
Typical Pro series protection has decoupling elements in the form of special resistors, which, despite the small size of carry high power for a long time. Heating of the flowing current causes the increase of the resistance, which provides electrical decoupling between protective steps. This is necessary in order to ensure an adequate response to the surge of small and big power. Both resistors and PTC thermistors have a very high inertia time, which entails the risk of a pulse on the secondary side of the transformer and damage to the physical layer Ethernet controllers. This is caused by a sudden impulse current, which occurs when a high potential equalization between devices. This risk arises when the terminal devices (IP cameras) are installed on high poles, roofs or grounded metallic structures.

PRO series solution
Extreme Series is the latest solution in the form of super-fast circuit breakers, performed in MOSFET technology. They provide a very low electrical resistance during normal operation, so the system LAN does not cause any loss. When the current flow is controlled by the intensity and rise above the predetermined value, the input circuit automatically disconnected from the output circuit at the time of maximum 1us. This ensures complete isolation of the physical layer of the LAN cable to the time when the risk and results in faster build up of strain on the elements of protection, allowing faster reaction takes place on the resulting surge. Time surge can last continuously for any length of time and after his resignation electrical connection is automatically restored within 1us. This design significantly increase the efficiency and speed of tripping and contributes to its very high resistance to damage.
To avoid damage to the circuit breakers, it is necessary to connect the ground wire.
