Ubiquiti UACC PSU 54V 1200W Hot Swappable AC DC Power Module 54V 18.35A

Ubiquiti UACC-PSU-54V-1200W Hot-Swappable 54V Power Module

The Ubiquiti UACC-PSU-54V-1200W is a proprietary hot-swappable AC-to-DC power module designed for compatible UniFi equipment with modular power-supply bays. It delivers a regulated 54V output for high-power enterprise networking applications.

When connected to 200–240V AC input power, the module provides up to 1,200W of total output. When operated from 100–120V AC, its maximum output is reduced to 1,000W. This input-voltage distinction is important when calculating available system and PoE power.

The hot-swappable design allows a compatible host device to support power-supply servicing or redundant power configurations without a complete shutdown, subject to the host device’s supported power mode, installed modules, active load, and manufacturer procedures.

Power Output

The UACC-PSU-54V-1200W provides 54V DC output at up to 18.35A. Maximum output depends on the available AC input voltage: the module supplies up to 1,200W on 200–240V AC circuits and up to 1,000W on 100–120V AC circuits.

Actual system and PoE availability is determined by the host device, the number and type of installed power modules, the selected shared or redundant operating mode, the AC input voltage, and the host device’s own power consumption.

Hot-Swappable Modular Design

The module is designed for insertion into a compatible UniFi hot-swappable power-supply bay. In supported redundant configurations, a module can be serviced without shutting down the host device when the remaining power supply can safely support the active system and PoE load.

Power Connection

An IEC C14 connector accepts compatible AC power cables and supports 100–240V AC input at 50/60 Hz. A power cable is included with the module.

Compatibility

This is a proprietary 54V CRPS power module and is not a universal replacement supply. Compatibility must be confirmed by exact host model, required output voltage, module wattage, connector and mechanical format, supported firmware, and the manufacturer’s approved power configuration.

Ideal Applications

• Replacement power supply for compatible UniFi enterprise switches
• Adding a second approved module for power redundancy
• Increasing available power on host systems that support 1,200W modules
• High-density PoE, PoE+, PoE++, and PoE+++ switch deployments
• Enterprise and campus networks requiring serviceable power modules
• Network installations requiring hot-swappable power-supply maintenance

Compatible Products

The UACC-PSU-54V-1200W must be installed only in UniFi equipment that explicitly supports Ubiquiti 54V, 1,200W hot-swappable power modules. Matching the output voltage alone does not establish compatibility.

• Ubiquiti ECS-48-POE Enterprise Campus 48 PoE Switch – officially specified with two hot-swappable 1,200W AC/DC power modules and supports shared or redundant power operation.
• Ubiquiti ECS-24-POE Enterprise Campus 24 PoE Switch – officially supports configurations using two 1,200W power modules for increased shared-mode or redundant-mode PoE availability.

Important: This is a proprietary 54V CRPS module. It is not interchangeable with the UACC-PSU-54V-600W, UACC-PSU-12V-550W, UACC-PSU-12V-150W, EdgePower modules, standard ATX power supplies, or other power modules merely because they use a similar enclosure or connector.

Input-voltage limitation: The module supplies up to 1,200W only with 200–240V AC input. Maximum output is 1,000W when connected to 100–120V AC. The host device may reserve part of this power for its own operation, so module output should not be presented as the final available PoE budget.

Hot-swap limitation: Do not remove an active module unless the remaining power source can support the host device and its current PoE load. Follow the host device’s installation and power-redundancy instructions.
