- Multi-stage protection provided for all four pairs of conductors in Cat. 5e / Cat. 6
performance with minimal interference.
- An equal level of protection ensured for the core-to-core voltage used for PoE.
- Compact module can be easily installed in a tight space of CCTV camera’s junction box.
M-System’s model MDCAT is specifically designed to protect communication devices connected via Ethernet LAN from lightning surge entering through network cables.
Multi-stage protection is provided for all four pairs of conductors in Cat. 5e / Cat. 6 performance (1000BASE-T, 100BASE-TX and 10BASE-T) with minimal interference, tested for up to the maximum 100 meter segment length as defined in the standard. An equal level of protection is ensured for the core-to-core voltage used for PoE/PoE Plus.
Compact module can be easily connected in rolled-up LAN cables and installed in a tight space of CCTV camera’s junction box. It can also be snapped on a DIN rail for high-density mounting inside a central monitoring panel together with Ethernet switches. Individual earth wiring is not necessary when you ground the DIN rail.
Shield terminal, frame grounding, signal grounding may be provided or not depending on the protected devices. The MDCAT is provided as ‘grounding’ mode with a shortcircuit bar connecting the shield and the ground terminals. Removing the bar turns the module to ‘floating’ mode, so that a ground loop problem can be easily fixed. By separating the shield and the ground, the former terminal can be used for individual signal grounding.
