Fonte de alimentação ALLNET EM10951M 54V 1,85A saída, ficha DC 5,5×2,1 mm

ALLNET EM10951M is an external 54V DC power supply that provides a regulated 1.85A output through a 5.5×2.1 mm barrel connector. Designed for use with networking equipment and other devices that require a stable 54V source, this adapter is suitable for desktop placement or wall-mounted installations where a compatible voltage and connector are needed. The unit delivers consistent output to support continuous operation and reduce the risk of device resets due to power fluctuations.

Advantages

The adapter offers a steady 54V regulated output with a maximum current of 1.85A and a commonly used 5.5×2.1 mm DC plug, ensuring compatibility with many networking devices. Its external design allows for easy replacement or relocation without opening equipment. The regulated output helps protect connected devices from voltage spikes and provides stable performance for extended operation.

Suitable for

• Powering networking equipment such as switches, small routers, and PoE injectors that accept 54V input
• Replacing a failed external 54V adapter with a matching connector and current rating
• Desktop and wall-mounted installations where a compact external power supply is required

Key specifications

• Output voltage: 54 V DC
• Maximum output current: 1.85 A
• Connector type: 5.5 × 2.1 mm barrel plug
• Form factor: external/adaptable for desktop or wall use
• Output regulation: regulated DC output designed for stable voltage delivery

How to use

Confirm that the target device accepts a 54V DC input and that the 5.5×2.1 mm barrel connector matches the device inlet polarity and dimensions. Connect the barrel plug to the device while the adapter is unplugged from mains, then connect the adapter to the AC supply. Verify device operation and ensure there are no unusual noises, heating, or error indicators. Disconnect the adapter from mains before disconnecting the barrel connector.

Recommendations

Use the adapter in a dry, well-ventilated location away from direct heat sources. Ensure connector polarity and voltage compatibility before use. If the device draws close to the maximum current rating, monitor for extended heating and allow for adequate ventilation to maintain reliable operation.
