Decentralized Parallel Architecture – DPA™ - unique to ABB
The modular approach called Decentralized Parallel Architecture (DPA™) enables multiple units to be parallel connected for redundancy (n+1) where each module is a separate UPS in itself, sharing no common components with the other modules.
The direct benefit is: if one module has a problem, the problem cannot spread, and the power supply stays online. The unique architecture also has further benefits: the units are built for fast and easy maintenance, a module can be replaced in under 10 minutes by the crew.
