120W DC Output for Reliable NAS Power Backup

The UGREEN NAS UPS US3000 provides up to 120W of DC output power, making it suitable for compatible NAS systems that operate within its specified electrical limits. By supplying power directly through a supported DC connection, it provides a dedicated backup solution for network storage devices without requiring the NAS to depend solely on the main power supply.

Its 12V DC output supports a maximum current of 10A. The actual power required by a NAS depends on the device model, installed drives, and workload. Always confirm the NAS power requirements and the manufacturer's compatibility information before connecting the UPS.

12000mAh Lithium-Ion Battery Backup

The US3000 incorporates a 12000mAh lithium-ion battery rated at 43.2Wh. This integrated battery is designed to supply backup power when the primary power source becomes unavailable, helping a compatible NAS remain operational during short power interruptions.

Actual backup duration depends on the connected NAS, the number and type of installed drives, operating workload, battery condition, and power-management settings. UGREEN indicates approximately 10 minutes of backup runtime in a stated usage scenario, but this should not be treated as a guaranteed duration for every configuration.

The battery capacity is intended to support short-term power continuity and safe shutdown procedures rather than provide extended operation throughout a prolonged outage.

Zero-Second Power Transfer for Continuous Operation

Unexpected power loss can interrupt file transfers, storage operations, and other activities performed by a NAS. The UGREEN US3000 specifies a zero-second transfer time, allowing the battery backup to take over without a specified interruption when the main power supply fails.

This feature helps reduce the risk of abrupt shutdowns and interrupted write operations. However, it does not eliminate every possible cause of data corruption or hardware failure. Maintaining separate backups of important files remains essential for comprehensive data protection.

Smart Monitoring and Automatic NAS Shutdown

The UGREEN US3000 supports data communication with compatible NAS systems, enabling supported monitoring and power-management functions. When configured appropriately, the NAS can use the UPS connection to respond to a power interruption and initiate a controlled shutdown.

Depending on the compatible NAS model and software configuration, users can also configure supported startup and shutdown behaviour when power is interrupted or restored. These functions help reduce the need for manual intervention during unexpected outages.

Available features depend on the connected NAS, its operating system, firmware version, and configured settings. Confirm that the required UPS monitoring and shutdown functions are supported by your specific device.

Multiple Safety Protections for Stable Operation

The US3000 incorporates multiple safety protection mechanisms intended to support dependable battery backup operation. The manufacturer's product information describes nine-level safety protection designed to help protect the power system and connected equipment.

These protections contribute to safer operation during normal use and certain electrical fault conditions. For reliable performance, use the specified power adapter and compatible connections, keep the unit in a dry and well-ventilated environment, and avoid exceeding the rated output capacity.

Compact DC UPS Design for Storage Setups

Unlike a conventional AC UPS designed to power a variety of mains-powered devices, the UGREEN US3000 is a dedicated DC backup solution intended for compatible UGREEN NAS systems. Its compact design makes it suitable for home storage setups, office environments, and small-business installations where space efficiency is important.

The dedicated DC configuration provides a practical way to add backup power to a compatible NAS without selecting a larger AC UPS solely for that device. Compatibility, input requirements, output capacity, and supported communication features should still be checked before installation.
