Ampt Battery Converters deliver full power in less than 1 millisecond to stabilize power during GPU load changes so compute runs without interruption.
Ampt converters are connected in parallel to scale DC power with the rack, row, or data hall using the same 80 kW building block.
Each Battery Converter delivers 80 kW (100 A) from a compact, rack-mountable 2U unit, packing high power into minimal rack space.
N+1 redundancy maintains full power to the GPU if a unit goes offline. On a 1.5 MW GPU rack, Ampt’s 80 kW converters only require 5% more installed compacity versus 100% more for a MW-class converter.
The Battery Converter delivers up to 99.2% peak efficiency by using MOSFET switching to lower electricity and water-cooling costs compared to IGBT switching used in MW-class converters.
Ampt Battery Converters have a built-in web application for local control, configuration, and testing, plus Modbus TCP for SCADA commands and telemetry.
The Battery Converter input follows the battery’s state of charge while its output holds a steady 800 VDC at the rack. The battery-backed DC bus ensures a stable load to the grid.
