It converts a three-phase AC supply into a regulated 800Vdc bus for AI and high-density server racks in hyperscale, colocation and enterprise data centers. One shelf delivers up to <strong>110kW<\/strong> from six hot-pluggable 18.5kW rectifier modules, managed by a hot-pluggable controller.<\/p>\n<p class=\"prod-description\">Distributing power at 800Vdc instead of a low-voltage bus reduces the current for the same power by a factor of about 15: at 110kW the shelf output carries approximately 139A (at 790Vdc), while a 52Vdc bus would need about 2,115A. Lower current allows smaller busbars and cables and reduces conduction losses in the rack.

Full 110kW output is available from 415 to 528Vac; from 311 to 415Vac the rating is 100kW. Output regulation accuracy is \u00b10.25% at 100% load, with ripple and noise \u22648Vp-p. For higher power, <strong>up to six shelves can operate in parallel<\/strong> with current sharing, for a total of up to 660kW.<\/p>\n<p class=\"prod-description\">The controller provides data center telemetry through an RJ45 Ethernet port (<strong>Redfish and SNMP<\/strong> northbound; PMBus\/SMBus to the rectifiers), a Web GUI, three-colour status LEDs and field firmware upgrade through the bootloader \u2014 see our note on <a href=\"\/?p=23940\">manageable power converters with PMBus and Redfish<\/a>. The shelf also supports a battery backup unit (BBU) interface.
