Delta, LITEON and the Component Makers Moving UpThin moat

Read the ecosystem lists published around the 800 VDC architecture carefully and there are two tiers. The data-center power system providers are the familiar names — ABB, Eaton, GE Vernova, Hitachi Energy, Mitsubishi Electric, Schneider, Siemens and Vertiv. Underneath them sit the power component providers: BizLink, Delta, Flex, LITEON, Megmeet and others¹. Vertiv competes today only with the first list. The question is how long the second list stays where it is.

The economics push in one direction. Component makers, mostly Asian contract manufacturers, operate at cost structures a US-based systems integrator cannot match, and they are already inside the racks. Historically what kept them out of the systems business was the integration difficulty — knowing how power, cooling, monitoring and service fit together in a live data hall. An open reference architecture, as the previous page argues, reduces exactly that barrier by publishing the answer.

This is the commoditization risk arriving from below rather than beside. It will not take flagship projects first; it will take the standardizable portions — busway, distribution, rack-level components — where the specification is settled and the buyer sees interchangeable parts.

The tell is mix, not share. Watch whether Vertiv's growth increasingly comes from integrated systems and services rather than discrete hardware. A company whose product line is being hollowed out from the bottom keeps growing for years while the average quality of its revenue quietly declines.
