This is a high-performance isolation element (transformer) that electrically isolates LAN cables. It isolates the network environment and prevents electric shock accidents through signal lines. It reduces common-mode noise in LAN cables and helps prevent problems with connected devices. Features: ・High voltage (AC4000V for 1 minute) ・Transmission bandwidth (100KHz to 100MHz) Usable environments: ・LAN/Ethernet (10BASE-T/100BASE-TX) Modular format: ・RJ45 (8-pin)
