Socomec has announced the DELPHYS XL+ uninterruptible power supply (UPS) system, designed to increase rack density in data centers. The hardware has been launched as a commercial product featuring modular, doorless architecture.
Why it matters
As modern data centers struggle with increasing power demands and limited floor space, hardware that integrates power density with high-efficiency cooling is critical to scaling operations. This system addresses those constraints by optimizing the power path for large-scale infrastructure.
The system utilizes 125kW hot-swappable silicon carbide power modules to reach 98 percent efficiency in online double-conversion mode. This architecture reduces cooling requirements by 12 percent compared to the market average and cuts the operational footprint by up to 30 percent.
The players
Socomec
An industrial group specializing in low-voltage energy storage and power management hardware for critical infrastructure.
The details
The DELPHYS XL+ employs a doorless configuration, which eliminates the traditional requirement for clearance space to swing doors open in narrow aisles. Internally, the unit relies on silicon carbide — a high-performance semiconductor material that handles high voltages more efficiently than traditional silicon — to minimize energy loss during power conversion. All serviceable components are accessed via hot-swappable power modules, allowing maintenance crews to replace parts without interrupting power flow to the server racks.
Timeline
September 29-30, 2026: The DELPHYS XL+ made its official debut at Data Centre World Asia.
The Tech Race
The transition to silicon carbide technology in UPS hardware reflects a broader industry movement to extract higher power densities from standardized rack footprints. This development directly competes with legacy insulated-gate bipolar transistor (IGBT) designs that have dominated the data center power market for the last decade.
Data center operators can expect to gain floor space through the unit's doorless physical design, which removes the need for wide access aisles. Maintenance teams will transition to a modular workflow, as the hot-swappable power modules allow for component replacement without decommissioning the unit.
The takeaway
The DELPHYS XL+ represents a shift toward more compact, high-efficiency power infrastructure that prioritizes modular repairability over legacy fixed-chassis systems. Engineers and facility managers should monitor the rollout of this system to benchmark their facility's cooling overhead against the 12 percent reduction metric.
