Surge Protector EWIMAR PTF-68R-EXT/PoE — Gigabit LAN PoE, MOSFET, 8 Channels

EWIMAR PTF-68R-EXT/PoE is an 8-channel surge protector engineered for Gigabit Ethernet networks with Power over Ethernet (PoE) support. It uses MOSFET-based protection to limit transient overvoltages and protect LAN ports and connected PoE devices from spikes caused by lightning-induced surges, switching transients or ground potential differences. The unit is suitable for both indoor and outdoor PoE deployments where line-level protection and minimal impact on signal integrity are required.

Advantages

The MOSFET protection design provides low clamping capacitance and fast response to transient events while maintaining signal fidelity for Gigabit LAN links. Eight protected channels allow simultaneous safeguarding of multiple Ethernet pairs or independent PoE lines. The device is compatible with Gigabit data rates and PoE power delivery, offering a balance between robust surge attenuation and minimal insertion loss. Its compact form factor enables integration near switches, access points or camera junctions without significant space requirements.

Suitable for

• Protecting network switches and PoE injectors in office and industrial environments
• Safeguarding IP cameras and video surveillance systems, including outdoor installations
• Protecting wireless access points and point-to-point Ethernet links
• Use in telecom closets, distribution panels and equipment racks where multiple LAN ports require protection

Key specifications

• Number of protected channels: 8
• Supported network speed: Gigabit Ethernet
• PoE compatibility: supports Power over Ethernet pass-through/protection
• Protection technology: MOSFET-based transient suppression
• Signal integrity: designed for minimal impact on high-speed Ethernet links
• Installation: inline/port-level mounting near equipment or patch panels

How to use

Install the surge protector inline between the network cable and the device or port you wish to protect, following site cabling and grounding practices. Ensure the unit is placed so all protected pairs pass through the device and that PoE polarity and power class remain compatible with the powered device. Verify proper termination and continuity after installation, and test network connectivity at Gigabit speed to confirm signal integrity. If the protected location is exposed to the elements, mount the device in an appropriate weatherproof enclosure and provide correct bonding to the building ground.

Usage recommendations

Use this surge protector as part of a layered protection strategy: combine port-level protection with building grounding, upstream surge protectors and proper cable routing. Periodically inspect the unit after severe electrical events and verify continued network and PoE performance.
