4-Port PoE Injector IEEE 802.3af/at Compliant Fanless Design Wall Mountable
Overview:
A 4-Port PoE injector (also known as a Power over Ethernet mid-span device) delivers both data and power through a single cable, eliminating the need for separate electrical wiring. As a versatile PoE power supply module, this model is among the most popular choices for network expansions, offering plug-and-play flexibility.
Key Features:
4x RJ45 PoE ports – Enables simultaneous power delivery to multiple devices such as IP cameras, wireless access points, and VoIP phones.
Dual-Function Port Groups – One set connects to standard Ethernet switches, while the other provides PoE+ compliant output (combining power and data transmission).
Mid-Span Design – Seamlessly integrates into existing networks without requiring switch upgrades.
Ideal for small to medium deployments, this 4-port PoE injector ensures reliable, high-efficiency power sourcing for your connected devices.
Power Over Ethernet (PoE) Injector – Reliable & Flexible Power Solution:
✔ Multi-Device Power Supply – Delivers stable PoE (Power over Ethernet) to HD network cameras, IP phones, Wi-Fi access points, and other 802.3af/at-compatible devices via Cat5e/Cat6 cables.
✔ High-Speed Data Transmission – Features 8x 10/100M RJ45 ports (4x PoE + 4x non-PoE) for seamless network expansion.
✔ Wide Voltage Input (90V~264V AC) – Supports global power standards, ensuring compatibility in different regions.
✔ Dual PoE Standards Support – Compliant with IEEE 802.3af (15.4W) and IEEE 802.3at (25.4W), offering flexible power options for various devices.
✔ Versatile Power Delivery Modes – Supports both Alternative A (data line pair 1/2+, 3/6-) and Alternative B (spare pair 4/5+, 7/8-) wiring methods.
✔ Silent & Compact Design – Fanless cooling system with natural heat dissipation, making it ideal for office, surveillance, and small network deployments.
✔ Space-Saving Installation – Compact size allows for desktop or wall mounting, perfect for clutter-free setups.
