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