Προστασία υπέρτασης PoE Digitus DN-95421

The DIGITUS Surge Protector provides surge protection up to 10 kV for network and PoE devices, designed for industrial environments. It supports Gigabit data transmission (10/100/1000 Mbps) and PoE standards up to PoE++ (IEEE 802.3af/at/bt). The single-port module features one RJ45 input and one RJ45 output and is intended for installation on a 35 mm DIN profile rail, which can also serve as grounding. The device is specified for a wide operating temperature range from -40 °C to +85 °C and offers protection against weather and lightning effects.

Advantages

Compact DIN-rail design allows simple snap-on mounting and integration into industrial cabinets. Supports Gigabit networks and full PoE compatibility up to PoE++ for protected power and data transmission. High surge protection rating up to 10 kV provides reliable defense against transient overvoltages. Wide temperature range and robust construction make the unit suitable for harsh environmental conditions.

Key specifications

• Surge protection level: up to 10 kV
• Data rates: 10/100/1000 Mbps (Gigabit)
• PoE support: IEEE 802.3af / 802.3at / 802.3bt (PoE, PoE+, PoE++)
• Ports: 1 x RJ45 input, 1 x RJ45 output
• Mounting: 35 mm DIN rail (snap-on)
• Operating temperature: -40 °C to +85 °C
• Application: industrial network and PoE devices, outdoor/weather-exposed installations

How to use

Mount the surge protector by snapping it onto a standard 35 mm DIN rail inside the distribution cabinet; the rail can serve as grounding. Connect the network cable from the network source to the RJ45 input and the protected line to the RJ45 output. Ensure PoE power levels and cabling meet the supported IEEE 802.3af/at/bt standards. Verify grounding and network continuity before putting connected equipment into operation.

Recommendations

For optimal protection, install one surge protector per network line feeding sensitive equipment such as IP cameras, PoE switches or access points. Confirm proper grounding of the DIN rail and use shielded cables if required by the installation environment.
