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

Mã sản phẩm : KLZ.NET
Giá bán : Liên hệ
Mô tả :

Tiêu chuẩn IEEE 802.3af & IEEE 802.3at

Xuất xứ: Kumwell/ Thái Lan

Ứng dụng: bảo vệ đường truyền mạng LAN RJ45 Cat 5

Kumwell KLZ.NET series is intended to protect Local Area Networks (LAN) from overvoltage surges and electrostatic discharges created by switching transients in buildings. LAN systems are particularly prone to such disturb-ances because of the often long cable lengths involved which behave like antennas to such atmospheric disturbances.

It provides protection to all 4 lines in the UTP, and is Cat 5 capable.

Ground potential equalization between signal and protective (network or PC chassis) ground is provided.

PoE version (KLZ.NET-PoE) is designed to fulfil all versions of PoE applica-tions compatible with standards IEEE 802.3af and IEEE 802.3at.
