Use Case
When a rack is engineered for a 100kW+ AI load, three 33kW HPR shelves in parallel provide the DC bus with fault tolerance that 18kW shelves cannot reach without more shelf slots. The near-98% efficiency and high power factor under dynamic GPU load are what stop the AC feed from becoming the bottleneck.
