It uses RJ-45 interfaces and is finished in black plastic. The module is intended for setups where multiple low-voltage connections are needed in one location, such as linked TV equipment, PoE arrangements, or syringe-pump-style devices that accept DC power through RJ-45 connectors. By centralising power, it can reduce the number of separate adapters and the cable clutter that comes with them. The stated working temperature is 0C to 50C, storage temperature is -40C to 70C, and working humidity is 10% to 90% RH. These figures should be observed to keep the unit within its rated conditions. Before connecting any equipment, confirm that its voltage, polarity, and connector requirements match what this module supplies. The package contains one power supply box.\u003c\/p\u003e\n\u003ch2\u003eFeatures and Construction\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black four-port centralized DC power supply box with RJ-45 interfaces for TV, PoE, or syringe-pump equipment\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/8973\/2025-11-24\/original-image\/7d7b719a-5c7b-473b-b874-80672868d47b.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThe module is built around a four-port layout with RJ-45 interfaces and a black plastic housing. Its listed environmental tolerances cover typical indoor conditions, with a working temperature of 0C to 50C and working humidity of 10% to 90% RH. These details help you judge whether it suits the location where it will be installed.\u003c\/p\u003e\n\u003ch3\u003eMaterial and Build\u003c\/h3\u003e\n\u003cp\u003eThe outer housing is made of plastic in a black finish. Plastic keeps the unit relatively light, which can make it easier to position where space is limited. The black colour means it blends into dark equipment racks or cabinets without drawing attention. No additional coatings, shielding, or weatherproofing are stated in the source text, so the unit should be treated as suitable for dry indoor use within the quoted temperature and humidity ranges.\u003c\/p\u003e\n\u003ch3\u003eSize and Practical Fit\u003c\/h3\u003e\n\u003cp\u003eNo dimensions or weight are provided in the source text. Because of this, it is not possible to state the exact footprint of the unit or confirm clearance requirements. The four RJ-45 ports define the practical layout: four separate connections can be made from the one module. When planning an installation, leave enough room around the unit for the cables to bend naturally, and check the physical space available before ordering.\u003c\/p\u003e\n\u003ch2\u003eUses and Placement\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black four-port centralized DC power supply box with RJ-45 interfaces for TV, PoE, or syringe-pump equipment\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/8973\/2025-11-24\/original-image\/ab376184-b963-4783-a04b-463b68508211.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThe module is intended for Ethernet communication DC power supply applications that need several ports in one place. With four RJ-45 interfaces, it can serve TV equipment, PoE runs, or syringe-pump-style devices where individual power supplies would otherwise be needed. The black plastic housing and stated indoor tolerances suit installation in equipment cupboards, racks, or similar dry locations.\u003c\/p\u003e\n\u003ch3\u003eEvent or Professional Use\u003c\/h3\u003e\n\u003cp\u003eIn professional or event setups, several devices often need power in a single rack or table area. A four-port centralized module can reduce the number of separate power bricks, which may simplify packing, setup, and teardown. The RJ-45 connectors are familiar in networked audio, video, and data installations, so compatible cables are widely available. As no power output rating is given in the source text, always verify that the module meets the voltage and current needs of each device before use.\u003c\/p\u003e\n\u003ch3\u003eEveryday Home Use\u003c\/h3\u003e\n\u003cp\u003eAt home, the module can be used where a small group of compatible devices needs DC power through RJ-45 connections and you would rather not use several individual adapters. Its black plastic case is unobtrusive in a media cabinet or on a shelf. Keep it within the working temperature range of 0C to 50C and the working humidity range of 10% to 90% RH, and avoid locations where it could be exposed to moisture or extreme heat.\u003c\/p\u003e\n\u003ch2\u003eBenefits and Buying Value\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black four-port centralized DC power supply box with RJ-45 interfaces for TV, PoE, or syringe-pump equipment\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/8973\/2025-11-24\/original-image\/e0a85159-3653-4930-b393-e612dfd36447.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eConsolidating four connections into one module can cut down on cable clutter and the number of separate power supplies required. The stated temperature and humidity ranges give clear guidance on where the unit can be used. Reuse and low maintenance are supported by the simple plastic housing and the absence of any stated consumable parts.\u003c\/p\u003e\n\u003ch3\u003eReuse and Low Maintenance\u003c\/h3\u003e\n\u003cp\u003eThe module has no stated moving parts or replaceable filters, so routine upkeep is limited to keeping it clean, dry, and within its listed environmental limits. Because the four ports are built into one unit, the same module can be reused across different compatible setups rather than replaced each time a single adapter fails. Always disconnect power before cleaning or moving the unit, and do not use liquid cleaners on the plastic housing.\u003c\/p\u003e\n\u003ch3\u003eWhy Choose This Product\u003c\/h3\u003e\n\u003cp\u003eThis product is aimed at buyers who need a four-port DC power supply module with RJ-45 interfaces in a compact black plastic housing. Its listed working temperature of 0C to 50C, storage temperature of -40C to 70C, and working humidity of 10% to 90% RH give a clear picture of its operating limits. It is supplied as one power supply box. If your equipment requires a specific voltage or current that is not stated here, check with the seller before ordering.\u003c\/p\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black four-port centralized DC power supply box with RJ-45 interfaces for TV, PoE, or syringe-pump equipment\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/8973\/2025-11-24\/original-image\/fe7f3768-3994-466c-b1f7-2704cbe34fb6.webp\"\u003e\u003c\/div\u003e","brand":"qnaa1a-ru","offers":[{"title":"Black","offer_id":58866607423819,"sku":"CJZN132639301AZ","price":20.68,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1035\/6686\/8811\/files\/7d7b719a-5c7b-473b-b874-80672868d47b.webp?v=1792135584","url":"https:\/\/doverelle.com\/products\/four-port-centralized-tv-4ch-poe-syringe-box-dc-ethernet-communication-power-supply-module-plastic-black-rj-45-interface-0c-to-50c-working-temperature","provider":"Doverelle.com","version":"1.0","type":"link"}
