Product Description

1.5.3Battery Mode

The Liebert® GXT3™ enters Battery Mode when utility power fails or is outside acceptable values. The battery system supplies power through the DC-to-DC converter to the inverter to generate clean AC power for the connected loads.

When the Liebert GXT3 enters Battery Mode, the UPS sounds a half-second beep at 10-second intervals. When approximately 2 minutes of run time remains, the beeps sound every 5 seconds to warn that the battery is getting low (this Low Battery Warning is user-configurable).

In Battery Mode, the AC Input indicator goes Off and the Battery Level indicators illuminate. Each battery level indicator represents a 20% capacity level. As capacity decreases, fewer indicators remain illuminated. Refer to 7.0 - Troubleshooting.

For approximate battery run times, refer to 9.0 - Specifications.

NOTICE

Turning Off the Liebert GXT3 when it is in Battery Mode will result in loss of output power. If the UPS is turned Off manually, it must be manually restarted after utility power returns.

If the UPS is turned Off by a communication signal or because the batteries are depleted, it will operate as selected in the configuration program for Auto-Restart (Refer to 5.2.1 - Configuration Program).

1.5.4Battery Recharge Mode

Once utility power is applied to the Liebert GXT3, the Battery Charger begins charging the batteries.

1.5.5Frequency Converter Mode

All models of the Liebert GXT3 are capable of frequency conversion. Frequency Conversion Mode can be selected using the configuration program. Allowable frequency operating modes include:

•Auto Sensing - 50Hz or 60Hz – Bypass Enabled

•Auto Sensing - 50Hz or 60Hz – Bypass Disabled

•Frequency Converter - 50Hz – Bypass Disabled

•Frequency Converter - 60Hz – Bypass Disabled

The default for all models of the Liebert GXT3 is “Auto Sensing - 50Hz or 60Hz – Bypass Enabled.”

This modularity contributes to a more efficient use of resources and minimizes operational costs.

The UPS also incorporates advanced technologies such as double-conversion online architecture, which provides the highest level of power quality. This technology ensures that the output power is consistently clean and stable, effectively eliminating harmful voltage fluctuations and frequency variations. Consequently, connected load receives a pure sine wave output, preventing potential damage or operational issues with sensitive equipment.

Another key feature is the high efficiency rating of the Emerson UPS, which exceeds 95 percent in typical operating conditions. This high efficiency translates to reduced energy costs and a smaller carbon footprint, aligning with modern sustainability goals. The cooling system is designed to be efficient as well, ensuring optimal performance while maintaining a compact footprint.

The user-friendly interface enhances operability, featuring an intuitive LCD display that allows for easy monitoring of critical power parameters. Users can access real-time data related to battery health, load levels, and operational status, which aids in effective management of the power supply.

Battery management is another critical aspect of the Emerson UPS. It employs advanced battery management technologies to ensure optimal battery life and performance. Features such as intelligent battery testing and monitoring help predict potential battery failures before they occur, allowing for proactive maintenance and minimized downtime.

In summary, the Emerson 10-30 kVA, 208V UPS offers a combination of modularity, high efficiency, advanced technologies, and effective power management features that cater to the demanding needs of critical applications. With its reliable performance and user-friendly operation, this UPS solution is an excellent choice for organizations looking to protect their valuable equipment from power disturbances.
