Power supply Ubiquiti UACC-PSU-54V-1200W 1200W 100-240V

The Ubiquiti UACC-PSU-54V-1200W is an external power supply engineered for use with Ubiquiti ECS-24-PoE and ECS-48-PoE network switches. Delivering up to 1200W of output power, the unit accepts an AC input range of 100–240V at 50–60Hz and provides a 54V DC supply suitable for high-power PoE deployments. The compact metal enclosure measures 185mm x 73.5mm x 40mm and the power supply is finished in grey. The device meets CE, FCC and IC regulatory standards and is intended to provide reliable, continuous power for compatible Ubiquiti switches.

Advantages

The power supply offers high total output capacity (1200W) and wide AC input compatibility (100–240V, 50–60Hz), enabling operation in diverse electrical environments. Its compact form factor and moderate weight (0.75 kg) simplify installation and rack or shelf placement. Built to comply with CE, FCC and IC standards, the unit is designed for stable, standards-compliant performance with certified Ubiquiti ECS PoE switches.

How to use

Install the UACC-PSU-54V-1200W in accordance with the switch manufacturer’s installation instructions for ECS-24-PoE or ECS-48-PoE models. Connect the AC mains lead to a suitable 100–240V outlet and verify the input voltage and frequency match local supply. Attach the DC output to the designated power input on the compatible Ubiquiti switch using the provided or specified cabling. After connection, power on the unit and confirm the switch receives the required 54V supply and that PoE devices function as expected.

Recommendations

Use this power supply only with the specified Ubiquiti ECS-24-PoE and ECS-48-PoE models to ensure correct power delivery. Ensure adequate ventilation around the unit, secure AC connections to grounded outlets, and observe local electrical codes. For installations with multiple PoE devices, calculate total power draw to avoid exceeding the 1200W capacity.
