Low-Power Consumption Design

The 24-port Gigabit PoE switch (SP5200-24PGE4GC) employs two innovative energy-saving technologies in its updated architecture:

   --- Link Down Idle Mode: Compliant with IEEE 802.3az Energy Efficient Ethernet standards, this feature automatically reduces port power consumption when no active connection exists.

   --- Dynamic Power Adjustment: The system intelligently calibrates power output based on detected Ethernet cable length. Connections using cables under 20 meters achieve optimal efficiency, as the switch dynamically scales down power usage to match shorter-distance requirements.

These dual mechanisms enable substantial energy conservation for connected devices. By minimizing unnecessary power allocation through automated cable-length analysis and idle-state optimization, the SP5200-24PGE4GC significantly reduces operational power demands while maintaining full network performance capabilities. This intelligent power management approach enhances energy efficiency across network infrastructures without compromising connectivity standards.

802.3at Standard PoE+ Power Delivery Switch

The SP5220-24PGE4GC PoE switch delivers IEEE 802.3at/af compliant power and data transmission, supporting 24 ports with simultaneous gigabit speeds and up to 30W per port. With a total power budget of 400W, this compact solution efficiently powers diverse PoE-enabled devices while maintaining cost-effective installation. Its intelligent power allocation ensures optimal energy distribution across connected PDs (Powered Devices), ranging from low-power sensors to high-demand equipment. The switch's standardized implementation guarantees compatibility with existing network infrastructure while providing scalable power management for modern workplace requirements.

Electrical Surge Safeguard

Designed to meet IEC61643-21:2000 standards, this 24-port Gigabit PoE switch delivers 6kV surge protection across its PoE ports. This safeguards the device against lightning-induced surges and electrical spikes, ensuring stable operation in demanding environments such as industrial sites or outdoor installations.

Software-Defined Expansion Ecosystem

The switch features four built-in mini-GBIC SFP slots that support dual-speed 1000BASE-SX/LX fiber-optic modules, giving administrators greater flexibility in selecting SFP transceivers based on both transmission distance and speed requirements.

With multi-mode fiber, the range extends up to 2 km, while single-mode or WDM fiber supports distances of 20/40/60/100/120 km. This makes the switch ideal for enterprise data centers and distributed network environments where high-speed, long-distance connectivity is essential.

Plug & Play 24-Port PoE+ Switch – Built for System Integrators
The SP5220-24PGE4GC from Benchu Group is an enterprise-grade 24-port Gigabit PoE+ switch designed for SMB networks. Delivering IEEE 802.3at PoE+ power across all ports, this Layer 2 switch combines 24 Gigabit Ethernet ports with 4 flexible combo uplinks (RJ45/SFP) in a compact rack-mountable chassis. Its integrated PoE+ capability eliminates the need for separate power injectors, providing a streamlined and economical networking solution for powering IP phones, cameras, and wireless access points.
