Any type of sudden electrical surge can damage electronic equipment beyond practical repair. The DPE-SP110 Outdoor PoE Lightning Protector helps protect your network equipment from damage caused by lightning or other static buildup. In the event of an electricity surge, the DPE-SP110 will cut off or divert all the excess electricity while continuing to let through the amount of power necessary for your equipment to work as normal. This lightning protector is water-resistant, making it ideal for installation in outdoor environments.

High Surge Capability

The DPE-SP110 is built around a durable design featuring a higher surge capability and lower clamping voltage. The 10 kA impulse discharge current provides reliable surge protection, while the lower clamping voltage means the unit will activate faster by triggering at a lower voltage threshold. The DPE-SP110 is also IEC 61643-21-compliant, meaning it automatically covers all other existing international standards such as the ITU-T K-Series and IEC 61000-4-5.

High Speed PoE Connectivity

The DPE-SP110 can function as a transmitter for a PoE switch to deliver power and data through an Ethernet cable. This device helps protect all 8 pins and is compatible with all types of RJ45 cables. The DPE-SP110 can handle data rates of up to 1000 Mbps, and is backwards compatible with older 10/100 Mbps ports, while also providing support for both PoE and PoE+ standards.

Optimal Efficiency

Most traditional lightning protectors use either Gas Discharge Tube (GDT) and Silicone Avalanche Diodes (SAD) technology or a combination of both, resulting in unstable current and limited surge capabilities. When used in the field these lightning protectors have shown to be unreliable and still damage the connected equipment. The D-Link DPE-SP110 and DPE-110I feature an innovative patented design that balances surge current on each line to maximize surge capability, significantly enhancing reliability.

Safety Information:
Please read this safety information carefully. By installing or making use of the lightning protector, you acknowledge and agree to the statement herein.
- This product is sold pursuant to the terms and conditions set forth in the Warranty document. You acknowledge your review and acceptance of all terms and conditions of such Warranty.
- Proper installation is required for the ground cable to achieve its highest surge capability.
- Lightning protectors and lightning: It is a common misunderstanding that lightning protectors will protect equipment from lightning. Even the most effective lightning protectors cannot always fully protect equipment from the sudden increase in electrical pressure of several millions of volts transmitted by a lightning strike.
- A lightning/surge protector is a passive device with a variable life span, depending on the number of surges it receives. Its service life also varies depending on the amount of energy absorbed during each electrical surge. It is difficult to assess the current status of the lightning/surge protector based on its outer appearance or physical shape. For optimal performance, we strongly recommend that you replace your lightning/surge protector every two (2) years.
