PTF-1-PRO/PoE/DIN is professional surge protector designed for IP CCTV cameras mounted on DIN rail. It protect LAN connected devices before overvoltages, lightning,  and vandalism. Can be used to installations, where two end-point devices are placed outside of building like routers, switches, IPC cameras and other. For outside application additional IP66 housing must be used.

The protector eliminates overvoltages inside of each twisted pair over 6V up to 100A and 90V DC between wires and ground up to 4kA. The PTF-1 is compatible with UTP and FTP cable of 5 Cat standard, where 4-5 and 7-8 pairs are used only for Power Over Ethernet (PoE). It protect receivers before damages if power supply will be increased over 58V DC,

High quality printed circuits and low capacitance components give very small crosstalk and loss signal

To save high effectivity and fast reaction of protection, PTF-1 must be well grounded by shortest cable as is possible.
