## Long description

EWIMAR PTF-51-EXT/POE/MICRO is a compact external surge protector designed to safeguard PoE-powered devices and low-voltage signal lines from transient overvoltages. Built for installation on external cables and network equipment, the device diverts surge energy away from PoE, Ethernet and similar signal conductors, reducing the risk of damage from lightning-induced spikes or switching transients.
Advantages
The compact form factor allows placement close to entry points or equipment racks without occupying significant space. Designed specifically for PoE and signal lines, the protector offers targeted protection for data and power pairs while maintaining signal integrity. Installation on external cabling provides an additional layer of defense before surges reach sensitive devices. The unit is intended for use with low-voltage systems and minimizes downtime and repair needs by limiting peak transient voltages.
Suitable for
 Protection of PoE cameras, access points and VoIP devices
 Surge diversion on Ethernet links and low-voltage signal lines
 External cable entry points and outdoor networked equipment
Key specifications
 Application: external surge protection for PoE and low-voltage signal conductors
 Form factor: compact inline unit suitable for installation on cable runs
 Compatibility: designed for use with PoE-powered devices and Ethernet-type signal lines
 Protection type: transient overvoltage diversion for data and power pairs

How to use
Install the surge protector in-line on the external cable feeding the PoE or signal device, positioning it as close as practical to the cable entry or the protected device. Ensure correct wiring and secure connections according to the equipment’s cabling standard; maintain proper grounding or bonding of the overall installation as required by the site to ensure effective surge diversion. Verify that the protector’s mechanical mounting and environmental rating are suitable for the intended outdoor or exposed location.
Usage recommendations
