Industrial PoE Switch 3x1000M RJ45 + SC Fiber 12~48VDC Input and Voltage Booster

Mini Industrial 3-Port 10/100/1000T 802.3at PoE + 1-Port 1000X SC Ethernet Switch with 12~48VDC

Product Overview:

The LNK-IMC103GP Series is a compact industrial-grade Gigabit Ethernet switch designed for robust network performance in demanding environments. Featuring three 10/100/1000BASE-T PoE ports compliant with IEEE 802.3at standards, it delivers up to 30W per port to power devices such as IP cameras, wireless access points, and VoIP phones. The integrated 1000BASE-X SC fiber port provides reliable long-distance connectivity and noise immunity for backbone connections.

Equipped with an advanced voltage booster and wide-range 12~48VDC input, this switch ensures stable operation even with fluctuating power sources, making it ideal for solar-powered systems, renewable energy applications, and remote installations. Its hardened design withstands extreme temperatures, vibration, and shock, operating reliably in environments ranging from -40°C to 75°C.

This unmanaged switch offers plug-and-play deployment while meeting CE and FCC standards. It undergoes rigorous 100% burn-in testing to guarantee durability and longevity in industrial settings such as transportation networks, smart grid systems, and outdoor surveillance. The compact form factor and rugged metal housing make it suitable for space-constrained applications while providing an cost-effective solution for industrial Ethernet connectivity.
