ABB’s Xtra VFI / double conversion mode delivers maximum efficiency by dynamically adjusting the DPA 500 UPS configuration to match the load. In Xtra VFI / double conversion mode, the UPS automatically configures the number of modules that are active to match the load power.
Critical part of the UPS is the battery bank that provides the energy needed to ensure that a continuous flow of clean power is available to the critical process that the UPS is powering.
When specifying a new UPS, its power rating must be well matched to the job in hand or else it could fail just when it is needed. However, picking the correct power rating is not as straightforward as it may seem
It is clear that the transformer-free UPS design is better, which is why it now dominates the market. Read more about Major technical specification differences and Major differences …
Data centers are set to increase in size, number and complexity, upping the challenge to UPS products. Also, increasinggly sophisticated modular and containerized data centers will require more versatile power protection schemes.
