Chống sét lan truyền cho đường truyền mạng RJ45, Cat 5

Mã sản phẩm : KZ01.DTBCAT5
Giá bán : Liên hệ
Mô tả :

Tiêu chuẩn IEC 62305

Xuất xứ: Kumwell/ Thái Lan

Ứng dụng: bảo vệ đường truyền mạng RJ45 Cat 5

These surge protection devices intended for computer networks are specially designed for securing a faultless data transfer within computer networks category 5. They protect input electronic circuits of network cards against damage caused by surge effects in the Lightning Protection Zones Concept at the boundaries of LPZ 0A(B)-1 and higher according to IEC 62305. It is recommended to use these pro-tection devices at the input of protected equipment.

KZ01.DTBCAT5 series is suitable for mounting on a wall. KZ01.DTBCAT5-2P protects two pairs and KZ01.DTBCAT5-4P protects four pairs of conductors.

KZ01.NET-20A RJ/RJ protects one line with two protected pairs. It is supplied in a plastic housing enabling bolt fastening on a wall. Alternatively, it can be attac-hed to the protected appliance with a double-sided tape. Connectors RJ45 are at the input and output side of the device.
