TP-DCDC-1224 Passive PoE Injector 24V 24W DC-DC Converter 10/100

The TP-DCDC-1224 from Tycon Power is a compact and reliable Passive PoE Injector with an integrated DC-to-DC converter, designed to provide regulated 24VDC Power over Ethernet from low-voltage power systems. It accepts a wide 9-36VDC input and provides a regulated 24VDC passive PoE output, making it suitable for 12V and 24V battery-powered installations.

The unit combines DC-DC voltage conversion with a built-in 10/100Mbps PoE inserter, allowing power to be supplied over Ethernet cabling to compatible network equipment such as wireless access points, IP phones and security cameras.

With dual positive inputs, the TP-DCDC-1224 can be connected to two power sources, such as a primary supply and backup battery, providing greater flexibility for installations where power redundancy is required. The compact design helps maximise available installation space, while integrated protection helps safeguard the equipment against common electrical faults.

DC-DC Power Conversion

The TP-DCDC-1224 converts a variable low-voltage DC supply into a stable 24VDC output. The wide input range of 9-36VDC allows it to be used with a variety of 12V and 24V battery and low-voltage power systems.

This makes the unit particularly useful where network equipment needs 24V passive PoE but the available power source is a lower-voltage battery or DC supply.

Dual Power Inputs

The injector features two positive inputs and one common negative connection, allowing two power sources to be connected. This can be useful for applications requiring a primary power source together with a backup supply.

Using separate power sources can provide additional flexibility when designing wireless, security or remote networking installations where maintaining power availability is important.

Integrated Passive PoE Injector

The built-in PoE inserter applies the regulated 24VDC output directly to the Ethernet cable, allowing compatible PoE equipment to receive both network data and power through the same CAT5/CAT6 cable.

The unit uses the unused Ethernet pairs for passive power delivery:

• Pins 4,5: V+
• Pins 7,8: V-

The TP-DCDC-1224 is a passive PoE device and should only be connected to equipment designed to accept the corresponding passive PoE voltage.

Shielded Ethernet Connections

The unit accepts network data through a shielded RJ45 input and provides data and PoE power through a shielded RJ45 output. This makes it suitable for installations where shielded Ethernet connectivity is required.

Built-In Protection

The TP-DCDC-1224 incorporates multiple protection features designed to improve reliability and help protect connected equipment and the power system. These include:

• Short-circuit protection
• Over-current protection
• Reverse-voltage protection
• Over-voltage protection
• Surge protection
• Overload protection
• High-temperature operation capability

Applications

The TP-DCDC-1224 is suitable for a variety of low-voltage networking and PoE applications, including:
