3 Phase UPS Connection Diagram
The online double-conversion UPS acts as the core of the system. It continuously converts incoming AC power to DC. Then it converts the DC back to clean, regulated AC power. This design fully isolates the load from input power disturbances such as voltage fluctuations, frequency variations, and electrical noise.
An external battery bank or battery cabinet is connected to the UPS to provide uninterrupted backup power during mains failure. The UPS automatically switches to battery mode without interruption, ensuring continuous operation of connected equipment.
The conditioned and regulated output power from the UPS is delivered to various critical loads. This includes servers, data centers, security systems, networking equipment, and industrial devices. This ensures maximum protection and reliability.
