Power Supply Patton 08055DCUI 48V 1A DC adapter for network equipment

Patton 08055DCUI 48V 1A DC adapter is a compact external power supply designed for network and communications equipment that require a stable 48-volt DC input. The adapter delivers up to 1 amp of current, enabling consistent operation of low-power devices such as PoE injectors, VoIP gateways and other compatible network appliances. Its small footprint makes it suitable for desk or rack-side placement, easing replacement and maintenance in installations where a dedicated 48V source is needed.

Advantages

This 48V 1A DC adapter provides stable voltage regulation to reduce power-related interruptions and supports continuous operation of connected network equipment. The compact housing allows flexible placement in constrained spaces while the externally accessible connector simplifies installation and replacement. The adapter's output ratings match common 48V network devices, reducing the need for custom or modified power solutions.

Suitable for

• PoE injectors and midspan devices that accept 48V DC input
• VoIP gateways and small PBX units with low power consumption
• Network appliances such as media converters and small switches requiring 48V
• Desk- or rack-mounted equipment where a compact external adapter is preferred

Key specifications

• Output voltage: 48V DC
• Maximum output current: 1 A
• Output power: up to 48 W (nominal calculation based on voltage × current)
• Form factor: compact external adapter suitable for desk or rack-side placement
• Connector type: standard DC output plug compatible with many network devices (verify polarity and plug size)
• Intended use: external power source for low-power network and communications equipment

How to use

Confirm that the target device accepts a 48V DC input and that its required current does not exceed 1 amp. Verify connector polarity and plug dimensions before connecting. With the adapter unplugged from mains, insert the DC plug into the device's power inlet. Connect the adapter to an appropriate AC mains outlet using the supplied or recommended mains lead. After connection, power on the target device and verify normal operation. For replacement of an existing adapter, remove the original power source first and compare voltage, current and connector compatibility.

Usage recommendations

Use the adapter in environments within the specified ambient temperature range of the host device and avoid exposure to moisture or direct heat sources. Ensure adequate ventilation around the adapter and route cables to prevent strain on the DC connector. If multiple devices are present, label power leads to prevent mismatches. For critical installations, consider a UPS or redundant power arrangement to maintain service during mains interruptions.
