The DPA 250 S4 online double conversion modular uninterruptible power supply represents the latest technological innovation. This modular UPS is based on decentralized parallel architecture (DPA™), where every UPS module is practically its own UPS, having all the essential functional units needed for independent operation. DPA increases system reliability and availability compared to other modular UPS solutions in the market, as there is inherent redundancy between the UPS modules on all functional levels.
