KINGARD 48 V 30 W Gigabit PoE Injector

This injector delivers up to 30 W at 48 V over a single Ethernet cable to any 802.3af or 802.3at powered device. It handles 10/100/1000 Mbps data rates and uses pins 4, 5, 7 and 8 for power transfer. The unit requires no extra adapter and is ready for new installations.

Installers powering IP cameras.

The injector supplies power continuously on the PoE port without 802.3af/at detection, so it must only connect to equipment designed for PoE. Devices lacking PoE inputs or requiring detection handshake should use a different power method.

Always-on 30 W PoE output without detection

Because the injector feeds power regardless of the connected device, the single deciding specification is the absence of 802.3af/at compliant detection. Verify that the target device accepts passive 48 V PoE on pins 4, 5, 7 and 8 before connecting.

Questions about this item

Does the 30 W PoE output need any periodic maintenance or component replacement?

No, the injector has no moving parts or user-serviceable components, so it requires no scheduled maintenance or replacement under normal use.

What limit appears first when the injector runs continuously at full 30 W load?

The 30 W power ceiling is the first constraint; the unit delivers up to 30 W and will not exceed it regardless of demand.

How much heat or noise does the injector produce when powering a device all day?

It is a fanless, silent design; only mild warmth is generated during continuous operation.
