The role of 48V 2U rackmount lithium battery
Provide uninterruptible power supply to critical equipment
Communication base stations
The communication base station needs to maintain stable operation at all times to ensure the smooth operation of the communication network. Mains power may fail or be interrupted, and a 48V 2U rackmount lithium battery can be used as a backup power source. When the mains power is interrupted, the battery can quickly supply power to the base station equipment (such as wireless transceivers, signal processors, etc.) to ensure the continuous operation of the base station, avoid communication interruption, and maintain the normal communication needs of users, such as voice calls, data transmission, etc.

Optimize power usage and management

In the electricity supply, there are peak and trough periods of electricity consumption. The 48V 2U rack-mounted lithium battery can be charged with low-cost electricity during off-peak hours. During peak hours, the stored energy is released to power the load. This can not only reduce the electricity cost of users, but also reduce the power supply pressure of the power grid during peak hours, and realize the optimal allocation of power resources.

Smoothing renewable energy output
For renewable energy power generation systems such as solar and wind energy, their power generation is intermittent and fluctuating. The 48V 2U rackmount lithium battery can store the excess electric energy generated by renewable energy, and when the renewable energy generation is insufficient, the stored electric energy will be released, so that the output power will be more stable and continuous, and the utilization efficiency and reliability of renewable energy will be improved.

Applied to specific devices and systems
Industrial automation equipment
In industrial production, many automation equipment has high requirements for the stability of power supply. The 48V 2U rack-mounted lithium battery can provide stable power for the control system of industrial robots and automated production lines, ensure the precise operation of equipment and the continuity of the production process, and improve production efficiency and product quality.
