Product features:

1. Using supercapacitors or batteries as energy storage media.
2. Real time monitoring of DC bus voltage. When the DC bus drops below the compensation voltage, energy storage is released for bus compensation to maintain stable bus voltage.
3. Adopting high-speed DSP, with fast response speed and real-time compensation.
4. Modular design facilitates redundant configuration and operation maintenance.
5. Flexible access system, no impact on the system.
6. Complete protection functions.

Application scenario:

1. The frequency converter industry is widely used in power, chemical, textile, and other industries. Once lightning strikes or power grid faults occur, it can cause DC undervoltage shutdown of the frequency converter, affect normal processes, and cause significant losses. Therefore, a DC voltage support system is needed to maintain the normal operation of the frequency converter.

2. In other frequency converter applications, sudden loading or power loss in the power grid can cause the frequency converter to shut down, causing unplanned shutdowns in continuous production enterprises, resulting in huge economic losses and accidents. The installation of a DC voltage support system can timely support the busbar voltage from falling, wait for the restoration of the power supply, automatically exit after the power supply is restored, or ensure orderly production shutdown, ensure that the frequency converter does not power off, continue to work, improve power supply reliability, and avoid a large amount of economic losses for users.
