1-channel LAN surge arrester mounted on a DIN rail, designed for surge protection of Gigabit Ethernet, compatible with 1000Base-T and 1000Base-TX standards. It contains a direct discharge of large surge currents individually from each of wire conductor. A small amount of intermediary components reduces the scattering and absorption of electromagnetic interference. Very carefully designed multilayer printed circuits, a special production process and modern electronic components, allowed to obtain excellent transmission parameters required in cabling 6 category.

Built-in 3-level surge protection using MOSFET technology, effectively eliminate overvoltages induced in cabling and introduce additional separation for ground loop potentials between LAN devices. MOSFET technology reduces also the level of overvoltages that reaches a protected device (UP voltage level) during overvoltage to a value that is a little higher than the rated operating voltage (Un). Obtaining such parameters is impossible in the case of the most commonly used conventional solutions.

Independent PoE protection circuits eliminate the overvoltages between pairs 1.2 - 3.6 and 4.5 - 7.8 in the LAN cable. This solution protects power supplies of LAN equipment against damage due to lightning surges or uncontrolled voltage increase, for example as a result of damage to the PoE power supply. The solutions used are compatible with each PoE standard, including Hi PoE.

PTF-61-EXT / PoE / DIN is mounted near the LAN end points such as: PCs, PLCs, IPC cameras, radio transmitters, IoT devices. It is equipped with a housing installed on a DIN rail. Grounding of the limiter is carried out by means of a DIN rail, which should be connected to the PE line. Correct connection to the LAN network is also very important, it has been described in the user's manual. Do not reverse the DEVICE side with the LINE side, it may cause a malfunction of the surge arrester or even damage.

Using PTF-61 surge arresters in the protection of single LAN connection

 

The PTF-61 surge arrester can be used on the LAN switch side, however, for many channels, PTU-6xx or PF-6xx multichannel surge arresters.
