BOX PTF-1-EXT / PoE is an external surge PoE IP with the highest possible degree of protection for the safeguards of network devices exposed to a large extent on the effects of lightning, etc.
The device has KRONE connectors and RJ-45, so it is possible to connect any cable infrastructure configuration.
Extreme Series is the latest solution in the form of a super-high-speed circuit breakers, performed in MOSFET technology. They provide a very low electrical resistance during normal operation, so it does not cause any loss in LAN system.
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.
Protection is to suppress the shock pulse high power, resulting in relation to earth (gas tubes), and pulse induced between pairs of UTP wires during discharge. These pulses have a destructive effect on the Ethernet interface drivers, despite the use of galvanic insulation used on the hardware layer.
Are used to power pins 4,5 and 7,8, 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 15W 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.
