DITEK DTK-RM24NETS 24-Channel Network Surge Protector

The DITEK DTK-RM24NETS is a 24-channel, 1U rack-mount Ethernet and Power over Ethernet (PoE) surge protector designed to protect network switches, IP surveillance equipment, and connected devices from electrical transients. Supporting 10GbE data speeds, a 20kA per-pair surge current rating, and 144W power handling, it uses hybrid transient voltage suppression (TVS) diode and gas discharge tube (GDT) technology. The UL 497B-listed unit features shielded RJ45 connections, individually replaceable surge protection modules, and compatibility with IEEE 802.3af, 802.3at, and 802.3bt PoE standards.

DITEK DTK-RM24NETS 24-Channel Rack-Mount Ethernet and PoE Surge Protector

The DITEK DTK-RM24NETS Network Surge Protector provides centralized surge protection for up to 24 Ethernet or Power over Ethernet (PoE) circuits within a standard 19-inch equipment rack. Designed for commercial network infrastructure, IP surveillance installations, and access control systems, this 1U rack-mounted surge protective device helps safeguard network switches, network video recorders (NVRs), PoE injectors, wireless access points, and other connected electronics against transient overvoltages. The DTK-RM24NETS supports Ethernet data transmission speeds up to 10GbE and provides individual protection channels for network cable runs entering sensitive equipment. Its centralized configuration allows installers to protect multiple network connections within a single rack space, simplifying cable management and surge protection maintenance.

The DTK-RM24NETS uses hybrid transient voltage suppression (TVS) diode and gas discharge tube (GDT) technology to protect against differential-mode (line-to-line) and common-mode (line-to-ground) surges. Each channel provides a 20,000-amp surge current rating per pair, with a 7.22V differential-mode clamping voltage and 75V common-mode clamping voltage. The protector is designed for service voltages below 60VDC and supports up to 144 watts of power handling. It is compatible with IEEE 802.3af, 802.3at, and 802.3bt Type 3 and Type 4 PoE standards, accommodating connected devices with power requirements up to 100 watts under the IEEE 802.3bt Type 4 specification. The unit is UL 497B listed and meets the manufacturer's stated ANSI/TIA-568, RoHS, and CE requirements.

The rapid-replacement modular design allows technicians to remove and replace individual surge protection modules from the front of the device without removing the entire chassis from the rack. Each protection channel incorporates shielded RJ45 female input and output connections, supporting shielded network cabling and properly grounded installation configurations. The standard DTK-NETMS replacement module supports Ethernet and PoE circuits, while the optional DTK-EXTMS module provides surge protection for compatible PoE extender circuits. Installers can combine these module types within the same rack-mount housing to accommodate mixed network applications. The unit features a galvanized steel enclosure measuring 19 inches long, 2.9 inches deep, and 1.77 inches high, with an approximate weight of 4.4 pounds. It operates in temperatures from -40 F to 158 F (-40 C to 70 C) and environments with up to 95% non-condensing relative humidity.

The DITEK DTK-RM24NETS is intended for indoor installation in network equipment rooms, telecommunications closets, data cabinets, and security system racks. The manufacturer specifies installation near the protected equipment, with a minimum 10 AWG grounding conductor connected to the chassis grounding lug and a short, direct grounding path. Installation instructions establish a maximum measured ground resistance of 25 ohms, with 5 ohms or less recommended for optimal performance. Incoming network cables connect to the unprotected RJ45 inputs, while 3-foot RJ45 patch cables connect the protected outputs to network equipment. The DTK-RM24NETS provides a scalable protection solution for IP camera networks, PoE switches, access control equipment, VoIP systems, and commercial Ethernet infrastructure. Backed by a 10-year limited manufacturer warranty, its combination of 24-channel capacity, high-speed network compatibility, and field-replaceable modules helps simplify surge protection throughout professional network installations.
