Application
The Murata D1U54 2 kW family is an industry-standard 1U front-end supply for AI/GPU servers, storage enclosures and telecom central-office racks. Cold-redundant operation with current sharing lets a rack survive a single supply failure without derating, and the PMBus interface exposes input, output and fault telemetry to the BMC. QS Compute supplies the 2000 W 12 V AC-DC models with the HA-series variable-speed airflow options used in high-density GPU chassis.
