Mini Industrial 4-Port 10/100/1000T 802.3at PoE + 1-Port 100/1000X SFP Ethernet Switch with 12~48VDC Input and Voltage Booster

Industrial 4-Port PoE Switch with Voltage Booster Features

1. Flexible Fiber Connectivity
Equipped with 100/1000BASE-X SFP slots that support auto-detection for various SFP transceivers. This feature provides scalable fiber optic uplink options, enabling long-distance, high-bandwidth network expansion and seamless integration into diverse industrial backbone infrastructures.

2. High-Power PoE+ Capability
Features four 10/100/1000BASE-T RJ45 ports with auto-MDI/MDI-X and IEEE 802.3at PoE+ injection (Ports 1-4). This allows simultaneous data transmission and high-efficiency power delivery to connected devices like IP cameras, wireless access points, and industrial sensors, simplifying cabling and installation.

3. Robust Power Design & Versatile Budget
Operates on a wide 12-48VDC input range with an integrated voltage booster, ensuring stable performance in fluctuating power environments. It offers a substantial PoE budget—up to 120W at 48VDC—providing flexible power allocation for multiple high-demand powered devices (PDs) across various voltage inputs.

4. Industrial-Grade Hardware Resilience
Built with a dustproof (IP40) and sealed rugged metal housing, this switch withstands harsh conditions. Its industry-standard design ensures protection against particulate ingress and physical impact, while support for both DIN-rail and wall-mount installations offers versatile and secure deployment in control cabinets or on-site.

5. Extreme Environment Operational Reliability
Engineered for a wide operating temperature range from -40°C to 80°C (-40°F to 176°F). This exceptional tolerance, combined with support for 802.3x flow control for stable data transmission, guarantees uninterrupted and reliable network performance in extreme cold or heat, from outdoor solar farms to factory floors.
