DELTA SPT-POE/3-POE-DIN-E 4-Port DIN Rail PoE Switch/Extender, 3x PoE Out 30W, 10/100 Mbps, Unmanaged, -40 to 75°C

In industrial cabinets and remote enclosures, the DELTA SPT-POE/3-POE-DIN-E delivers both data and power over a single Ethernet cable. This unmanaged 4-port PoE switch/extender mounts directly onto a DIN rail and provides three PoE output ports, each capable of up to 30W, making it ideal for IP cameras, wireless access points, and other PoE-powered devices in harsh environments.

• Data rate: 10/100 Mbps Fast Ethernet, switching capacity 1 Gbps
• Power input: DC 48-57V via terminal block
• Mounting: DIN rail (35mm)
• Operating temperature: -40°C to +75°C
• Transmission distance: up to 100m standard, 250m in extend mode
• Special features: Extend mode, port isolation (VLAN), surge and ESD protection
• MAC address table: 1K entries, jumbo frame support up to 1536 bytes
• Management: Unmanaged, plug-and-play

Why choose it

Built for industrial networking, this switch operates reliably in extreme temperatures and provides robust protection against electrical surges. Its compact DIN rail housing saves space, while the extend mode allows longer cable runs for distributed devices. The port isolation feature enhances security by preventing direct communication between PoE ports, ideal for multi-tenant or surveillance applications.

Ideal use cases

• Powering IP cameras in outdoor or factory settings
• Connecting wireless access points in warehouses or campuses
• Extending network reach to remote sensors or controllers

Good to know

The switch is plug-and-play with no configuration required. It supports IEEE 802.3af/at PoE standards, automatically detecting powered devices. The rugged metal housing and wide temperature range make it suitable for deployment in unconditioned spaces such as attics, parking garages, or outdoor enclosures. For longer distances, the extend mode reduces data rate to 10 Mbps but extends reach to 250 meters, ideal for isolated devices.
