The UD series is a compact, all-in-one power conversion platform for large-scale energy storage. Each model \u2014 SW-2500K-UD, SW-3450K-UD, and SW-5000K-UD \u2014 delivers 2500 kW, 3450 kW, or 5000 kW of rated output and comes with an integrated step-up transformer (2500\u20135000 kVA, 0.69\/6\u201335 kV, DY11), allowing the unit to tie directly into medium-voltage grids from 6 kV to 35 kV. Merging the PCS and transformer into one enclosure reduces land use, transport effort, and project cost while increasing power density.<\/p>\n

 <\/p>\n

On the DC side, the series operates on a 1500 V architecture with a wide voltage window and supports grid-forming modes such as VF, PQ, and VSG. Multiple units can run in parallel off-grid with black-start capability, extending deployments from tens to hundreds of megawatts. The cabinets are protected to IP54\/IP55 for reliable performance in cold, hot, and high-salinity environments, with coordinated multi-layer protection for system safety. For integration, CAN\/RS485\/Ethernet plus Modbus, IEC 104, and IEC 61850 protocols enable remote monitoring and smooth connection to large-scale energy management systems.<\/p>\n
