The rack lives on the factory floor. Dust does not rate it.
Edge AI inspection cabinets sit beside presses and conveyor lines, breathing dust and absorbing vibration, while the same site's PV and battery plant needs distribution on the DC side — a category the AC rack catalog never shipped. Both belong to the factory engineer, not the IT ticket queue.
SITE CONDITIONS
| Environment | Dust and vibration duty in production halls |
|---|---|
| Source | PV + battery DC buses beside grid AC |
| Loads | Edge AI inference racks, bursty seconds-scale draw |
| Buffering | Ride-through until inverter or genset picks up |
| Management | Modbus TCP into SCADA, remote resets |
IT HARDWARE, FLOOR DUTY
Office-grade power does not survive hall duty.
Four gaps between the catalog and the plant.
| Gap | Condition at the rack | Failure it produces |
|---|---|---|
| Environment | Dust and vibration on the production line | Contact resistance climbs, fan life shrinks, connectors walk loose |
| Source mix | PV-storage DC bus beside grid AC | DC-side distribution is a new category, absent from AC catalogs |
| Load shape | Inference bursts on seconds-scale | Line-side sags from motor starts reach the compute cage unprotected |
| Staffing | No IT specialist on night shifts | A tripped edge node idles a line until someone drives in |
VOLTFAB RESPONSE
Rugged distribution on AC. LFP buffers on the DC bus.
Rack PDUs built for hall duty use secured HDOT outlets and locking cords, report over Modbus TCP so SCADA sees what the PLCs see, and let the NOC power-cycle a hung inference node remotely. On the PV-storage side, 51.2 V LFP packs on a UL 1973/9540A compliance path buffer the DC bus with CAN telemetry to the site controller, while hybrid LIC supercapacitor modules absorb sub-second sags at 100% DoD. Compute conversion runs through CRPS supplies at 12 V and 54 V with N+N redundancy — PDU MOQ from 10 pcs on 15–30 day leads.
PLANT BASELINE
Spec fields the plant engineer fills in.
Six lines that turn an IT catalog part into plant-rated hardware.
| Spec field | Plant requirement | VoltFab delivered value |
|---|---|---|
| Environment | Dust, vibration, secured connectors | HDOT outlets, locking cords, industrial build options |
| DC interface | Buffer the 48 V-class storage bus | 51.2 V LFP packs, UL 1973/9540A path, CAN telemetry |
| Compute conversion | 12 V / 54 V with redundancy | CRPS ladder, Titanium options, N+N hot-swap |
| SCADA visibility | Power data beside process data | Modbus TCP, SNMP v3, threshold alarms, remote switching |
| Milliseconds | Sub-second sag absorption | Hybrid LIC supercap modules, 100% DoD, -40~65°C |
| Program | Maintenance-window purchasing | PDU MOQ 10 pcs, 15–30 days; BBU MOQ 50 sets |
