Tycon Power TP-DCDC-4856G-VHP: 36-72VDC In, 56VDC 70W Passive POE Out DC-DC Converter

The TP-DCDC-4856G-VHP from Tycon Power is a high-power DC-to-DC converter and passive PoE inserter that’s engineered for reliability in demanding outdoor environments. Delivering 70W of passive PoE power on all eight Ethernet wires, it’s an ideal power solution for Ubiquiti airFiber antennas and rugged outdoor PTZ security cameras. With dual isolated inputs and a broad input range, this unit offers robust power delivery, seamless integration, and the kind of resilience that network deployments depend on when weather, distance, and equipment footprints matter most.

• High-power passive PoE output: Supplies 70W of passive PoE power across all 8 Ethernet wires, enabling energizing of high-power devices without separate injectors near the equipment. This means fewer inline components and a cleaner, more reliable power path to your devices.
• Wide input voltage range: Accepts 36–72 VDC, accommodating a variety of DC power sources and simplifying installations in dispersed or remote locations where multiple power rails might be used.
• Two isolated inputs for redundancy: Features dual isolated power inputs, enabling redundancy or the use of two separate power supplies for added reliability in critical deployments. If one supply fails, the other can keep the link up and the device powered.
• Output tailored for outdoor network devices: The 56 VDC output is designed to power high-demand outdoor devices, including Ubiquiti airFiber radios and PTZ security cameras, ensuring stable operation even in challenging outdoor conditions.
• Rugged, field-friendly design: Built to withstand outdoor deployments, with a compact form factor and simple connection strategy that minimizes installation time while maximizing uptime for communications links and security networks.

How to install Tycon Power TP-DCDC-4856G-VHP

Installing the TP-DCDC-4856G-VHP is straightforward, and its dual isolated inputs give you flexibility for redundant power configurations. Follow these general steps to ensure a safe and reliable setup:

1) Plan your power and placement: Choose a mounting location that is protected from direct exposure to moisture and extreme temperatures, yet close enough to the power sources and the network device to minimize cable runs.

2) Prepare the power sources: Ensure your two power supplies (one or two) are within the 36–72 VDC input range. Use proper DC power sources rated for the combined load to avoid voltage drop or overheating.

3) Connect the inputs: Attach the first power source to the primary input terminals and, if using redundancy, connect the second power source to the secondary isolated inputs. Observe polarity carefully to prevent damage—positive to the positive terminal and negative to the negative terminal on each input.

4) Route the PoE output to the device: Use a standard Ethernet cable to connect the TP-DCDC-4856G-VHP’s PoE output to the powered device (for example, a Ubiquiti airFiber antenna or an outdoor PTZ camera). Because this is a passive PoE solution on all 8 wires, ensure your device is compatible with 56 VDC passive PoE on its Ethernet interface.

5) Secure and protect the installation: Fasten the unit to a wall, pole, or enclosure as appropriate. Use weatherproof conduit, sealant, and cable management to maintain reliability in outdoor environments.

6) Power up and verify operation: Once connections are secured, power on the supplies. Confirm that the powered device boots normally and receives both data and power. If the device does not come online, recheck wire polarity, cable integrity, and the input voltage to ensure it remains within the specified range.

7) Routine maintenance and checks: Periodically inspect cable connections, mounts, and the power sources. Look for signs of corrosion or wear and replace components as needed to sustain long-term performance.

The TP-DCDC-4856G-VHP is designed to deliver a clean, stable 56 VDC PoE signal to your network devices while keeping the power path simple and centralized. Its dual-input arrangement reduces the risk of downtime due to a single power supply failure, making it particularly well-suited for remote installations where maintenance visits are infrequent and uptime is critical.
