PoE adapter Microconnect POEINJ-30W-IND

The Microconnect POEINJ-30W-IND is a single-port industrial PoE injector that supplies up to 55 V DC at 0.55 A over two-pair Ethernet output, delivering 30 W of power to remote powered devices. It supports 10/100/1000 Mbps data rates, provides 6 kV (10/700 µs) surge protection on the power output, and includes PD detection and classification to ensure power is applied only to standard-compliant devices. The injector is designed for indoor DIN-rail mounting, accepts 12–48 V DC input, operates from -40 °C to 65 °C, and reaches an effective link distance of up to 100 m over Cat5e/Cat6 cabling.

Advantages

The unit delivers up to 30 W to PoE PDs while remaining backward compatible with IEEE 802.3af devices, combines gigabit Ethernet data with power over two-pair output, and protects connected equipment with built-in surge protection. Its compact industrial housing with DIN-rail bracket simplifies installation in control cabinets or communication racks, and the internal detection chip prevents non‑standard devices from being powered.

Suitable for

• Powering wireless access points
• Supplying IP/network cameras
• Feeding VoIP phones and high-power Ethernet terminals
• Use in industrial or commercial network cabinets with DIN-rail mounting

When it may not be suitable

This injector is intended for indoor use only and requires a 12–48 V DC input supply; it is not suitable for direct connection to AC mains without an appropriate DC source. Devices that require more than 30 W of delivered PoE power or distances beyond 100 m over copper cabling may need an alternative solution.

Key specifications

• Surge protection: 6 kV (10/700 µs) on output
• Input voltage: 12–48 V DC
• Operating temperature: -40 °C to 65 °C
• Max cable distance: up to 100 m over Cat5e/Cat6
• Mounting: DIN-rail bracket
• Weight: 0.38 kg

How to use

Install the POEINJ-30W-IND onto a standard DIN rail inside an appropriate indoor cabinet. Connect a compatible 12–48 V DC supply to the injector input, then connect the data input from your network switch to the data port and the PoE output to the powered device using Cat5e/Cat6 cable. The built-in detection and classification circuitry will verify the PD before applying power. Verify that total cable length does not exceed 100 m for reliable operation.

What to consider before purchase

• Ensure available DC supply is within 12–48 V range
• Confirm the PD’s power requirement does not exceed 30 W
• Plan for DIN‑rail mounting space inside the enclosure
• Check required cable length and category (Cat5e/Cat6) for 100 m maximum

Usage recommendations

Use shielded or unshielded Cat5e/Cat6 cabling for runs up to 100 m, mount the injector in a ventilated indoor cabinet, and pair it with a stable 12–48 V DC power source. Verify device compatibility with IEEE 802.3at/802.3af standards to ensure proper detection and safe power delivery.
