The power EMS brand built for the AI rack.
VoltFab exists to make rack power accountable again: five product lines — Rack PDU, BBU, supercapacitor, CRPS PSU and busway — engineered, built and burn-in tested on one factory floor, with a supply chain already turning toward the 800VDC era.
MILESTONES
From PCBA floor to 800VDC roadmap.
PCBA line foundation
The first SMT line goes live as a PCBA build floor for industrial power boards — inheriting the placement, reflow and inspection discipline every later line still runs on.
Power category expansion
Board builds grow into finished power units: the floor adds power-test benches and takes on complete PSU and adapter programs instead of PCBA alone.
Five product lines formed
Rack PDU, BBU, supercapacitor, CRPS PSU and busway are organized as product lines under one quality system and one export-compliance chain.
Test & burn-in buildout
A dedicated AOI wall, X-Ray station and 100% burn-in aging room turn quality control from a department into the factory's exit gate.
AI rack generation
ORv3 48V backup, 54V CRPS shelves and busway programs ship for GB300-ecosystem racks drawing 30–142 kW per enclosure.
800VDC era layout
Engineering shifts to the next architecture: ±400V / 800V DC distribution, HVDC-ready PDU and busway platforms, and layered battery-plus-supercap backup.
HOW WE'RE ORGANIZED
One main floor, five satellite line sites.
The main EMS floor owns what must never fragment: SMT, assembly, test, burn-in and the compliance chain. Around it, each product line runs a dedicated satellite site — ems-pdu, ems-bbu, ems-supercap, ems-crps and ems-busway — with its own engineering bench but the same ISO 9001 system behind it. Buyers get specialist depth per line without giving up single-floor accountability.
WHAT WE HOLD TO
Three rules we build by.
Forge ahead
Adopt the next architecture before the order forces it: 54V rails, ORv3 backup, hybrid supercap buffering and 800VDC distribution all entered our roadmap as engineering programs, not sales answers.
Nameplate honesty
The nameplate is a contract. Efficiency, metering accuracy and ratings are the numbers we test to and sign — if a spec cannot survive the burn-in room, it never reaches the label.
One-floor accountability
SMT, assembly, test and aging share one floor and one serial record, so when a buyer asks why a unit failed, one vendor answers with data — not a chain of suppliers pointing at each other.
