This article covers DC5.5x2.1 インターフェイスを備えた信頼性 30W スプリッター ネットワーク接続を強化する 57V から 12V へのコンバーター スプリッター.
Overview
This device is a PoE (Power over Ethernet) splitter that converts 57V input power to 12V output, delivering up to 30W through a DC5.5x2.1mm connector. It includes a gigabit data pass-through, allowing you to maintain full network connectivity while supplying regulated power to non-PoE devices. The ABS plastic housing is durable enough for long-term use in home offices or small network setups. ## Specifications | Item | Specification | |------|---------------| | Input Voltage | 57V DC | | Output Voltage | 12V DC | | Max Power Output | 30W | | Output Connector | DC5.5×2.1mm (female) | | Data Rate | Gigabit (1000Mbps) | | Housing Material | ABS plastic | | Standards | IEEE 802.3af/at (PoE) |
Connectivity & Compatibility
The splitter accepts input from IEEE 802.3af (PoE) and 802.3at (PoE+) switches or injectors. Its DC5.5×2.1mm output is compatible with many IP cameras, wireless access points, and other network devices that use this power connector. The gigabit data pass-through ensures no speed loss for video streams or data transfers. Note: it does not support PoE++ (802.3bt), and the input must be 57V for proper operation.
Product Info
This product is sold on at a price of around ¥2,000, making it very affordable. Warranty details are available on the product page. Only the splitter unit is included; cables are sold separately. Its market position is as an entry-level accessory for easily setting up PoE power delivery. Compared to other options, it offers excellent value, especially for first-time PoE users.
Best Use Cases
Adding a non-PoE IP camera or access point to an existing PoE network without extra wiring Powering legacy 12V devices in a small office from a central PoE switch Cleaning up cable mess by combining power and data into a single Ethernet run Network enthusiasts needing a simple, low-cost way to extend power to remote devices while keeping gigabit speeds
