RDDY-3000 is a portable high-power outdoor power supply with a large lithium battery. It offers reliable 220V AC output, ideal for on-site testing and emergency backup.

The battery pack is the emergency power supply of the substation. In special circumstances where the AC incoming power supply disappears such as all substation transformers shut down or AC fault tripping in the station, the battery can ensure the normal operation of the AC and DC systems in the substation, effectively curb the expansion of the scope of the accident, and play a vital role in protecting the entire power supply. It plays an important role in the safe and stable operation of the system.
