DPA250 S4
DPA250 S4
DPA S4 redefines market standards with its advanced features, thanks to its transformerless IGBT converters. These converters feature a three-level topology with interleaving control to achieve a market-leading 97.6% efficiency at the UPS module level. This high efficiency not only reduces operating costs but also significantly contributes to sustainability.
The DPA S4 online double-conversion modular uninterruptible power supply incorporates the latest technological innovations. This modular UPS is based on a decentralized parallel architecture (DPA). This means that each UPS module is practically a standalone UPS, possessing all functional units for independent operation. By completely eliminating single points of failure within the UPS, DPA maximizes system reliability compared to other modular UPS solutions on the market.
