Ditek DTK-WM4NETS Wall Mount Ethernet and PoE Surge Protection

The DITEK DTK-WM4NETS is a commercial-grade, four-channel wall-mounted network surge protective device designed to protect Ethernet and Power over Ethernet (PoE) equipment against damaging transient overvoltages. Part of the DITEK NETS Series, the DTK-WM4NETS provides four independently protected Ethernet channels, data transmission speeds up to 10Gbps, 144-watt PoE power handling, and a 20kA-per-pair surge current rating. Its hybrid protection circuitry incorporates transient voltage suppression (TVS) diodes and gas discharge tubes (GDTs) to provide differential-mode and common-mode protection against electrical surges caused by lightning-related disturbances and switching events. Featuring shielded RJ45 female input/output connectors, rapid-replacement protection modules, and compatibility with IEEE 802.3af, 802.3at, and 802.3bt PoE standards, the unit supports network switches, NVRs, IP cameras, wireless access points, and network-connected access control equipment. The compact ABS housing measures 4.75 inches long by 2.93 inches wide by 2.36 inches high and supports wall mounting or optional DIN-rail installation. UL 497B listed and backed by a 10-year limited manufacturer warranty, the DTK-WM4NETS provides centralized Ethernet surge protection for commercial security, telecommunications, and network infrastructure installations.

DITEK DTK-WM4NETS Four-Channel 10GbE PoE Network Surge Protector, 20kA

The DITEK DTK-WM4NETS Wall-Mount Network Surge Protector provides centralized transient voltage protection for commercial Ethernet and Power over Ethernet installations requiring multiple protected network connections. Manufactured by DITEK Surge Protection as part of its NETS Series, the DTK-WM4NETS incorporates four independent surge protection channels with shielded RJ45 input and output connections, allowing multiple Ethernet cables to be protected before reaching sensitive network equipment. Designed for smaller networking installations where a full rack-mounted surge protection assembly may be unnecessary, the unit supports data transmission speeds up to 10 Gigabit Ethernet (10GbE) without the signal degradation associated with incompatible protective devices. Its four-channel architecture makes it suitable for protecting PoE network switches, network video recorders (NVRs), wireless access points, IP surveillance systems, networked access control equipment, and PoE lighting infrastructure. The wall-mounted configuration consolidates surge protection at a common equipment location, reducing the need to install separate single-channel surge protectors for every network cable. By limiting transient voltage exposure on connected Ethernet conductors, the DTK-WM4NETS helps reduce the risk of equipment damage and network downtime caused by electrical disturbances.

The DTK-WM4NETS incorporates hybrid multistage surge protection circuitry using transient voltage suppression (TVS) diodes and gas discharge tubes (GDTs). This combination provides protection against fast-rising transient overvoltages and high-energy surge events affecting Ethernet and PoE conductors. The manufacturer specifies a 20,000-amp surge current rating per wire pair, with protection provided in both differential mode (line-to-line) and common mode (line-to-ground). Published clamping voltage ratings are 7.22V for differential-mode protection and 75V for common-mode protection, measured under the manufacturer's specified testing conditions. The device is designed for service voltages below 60VDC and supports PoE power transmission up to 144 watts, accommodating compatible high-power Ethernet devices. Each protection channel includes shielded RJ45 female input and output connectors, allowing the device to be inserted in series with a standard Ethernet cable connection. The ABS housing measures 4.75 inches (121 mm) long, 2.93 inches (74 mm) wide, and 2.36 inches (60 mm) high, with a weight of approximately 9.6 ounces (272 grams). Manufacturer operating specifications include a temperature range of -40 F to 158 F (-40 C to 70 C) and relative humidity up to 95% non-condensing. The DTK-WM4NETS is UL 497B listed and conforms to applicable ANSI/TIA-568, RoHS, and CE requirements.

For modern Ethernet infrastructure, the DITEK DTK-WM4NETS supports IEEE 802.3af, 802.3at, and 802.3bt Power over Ethernet standards, including high-power applications requiring Type 3 and Type 4 PoE compatibility. Manufacturer documentation identifies support for 15.4W standard PoE, 30W PoE+, 60W Type 3 PoE, and 100W Type 4 PoE, with an overall power-handling specification of 144 watts. The unit's four-channel modular architecture allows individual surge protection modules to be replaced without replacing the entire wall-mount housing. The standard DTK-NETMS rapid-replacement module provides protection for Ethernet and PoE circuits, while the optional DTK-EXTMS module accommodates compatible PoE extender circuits. These module types can be mixed within the same housing according to the network's requirements, allowing one enclosure to support different protected Ethernet applications. The DTK-WM4NETS is particularly useful for commercial surveillance systems, distributed network switches, building automation equipment, networked door controllers, wireless access points, and low-voltage telecommunications installations where multiple cabling runs enter a common equipment location. Its shielded network connections also support a coordinated grounding arrangement for remote network equipment when properly terminated shielded twisted-pair (STP) cables and an appropriate grounding system are used. The related DITEK DTK-WM8NETS provides eight protected channels, while the DTK-RM12NETS, DTK-RM16NETS, and DTK-RM24NETS offer rack-mounted alternatives for larger network installations.

Installation of the DITEK DTK-WM4NETS four-channel surge protector involves mounting the compact enclosure near the network switch, PoE injector, NVR, or other equipment requiring protection. The unit's integrated mounting flanges support attachment to a suitable flat surface, while the optional DITEK DTK-DRK DIN-rail mounting kit provides an alternative arrangement for compatible network and equipment cabinets. Incoming Ethernet cables connect to the designated IN ports on the four protection channels, while outgoing shielded Ethernet patch cables connect from the corresponding OUT ports to the protected network equipment. DITEK specifies a minimum 3-foot (0.9-meter) equipment-side patch cable between the surge protector and protected equipment. The installation guide also requires a properly connected grounding conductor, with 14 AWG minimum ground wire and routing kept as short and direct as practical to maintain effective surge diversion. The shielded RJ45 connections can support grounding continuity to remote protected devices when the installation uses appropriately grounded shielded twisted-pair cabling. During commissioning, installers verify correct input/output orientation, grounding continuity, Ethernet link operation, PoE power delivery, and compatibility with the connected network devices. The rapid-replacement protection cartridges simplify servicing because individual modules can be exchanged without removing the complete wall-mounted assembly. The DTK-WM4NETS is a passive network surge protective device and does not generate PoE power, provide Ethernet switching, or function as an uninterruptible power supply. The housing must be installed in an appropriately protected location or within a suitable enclosure where environmental conditions require additional protection. Backed by a 10-year limited manufacturer warranty, the DTK-WM4NETS combines four-channel 10GbE protection, 20kA-per-pair surge capacity, high-power PoE compatibility, replaceable protection modules, and compact wall-mount construction for commercial security and networking applications.
