HOME / DESIGN GUIDES
Specify rack power like the people who build it.
Four working guides our engineers use to turn a chassis drawing or a floor plan into a buildable OEM program — the same math we run before quoting, shared up front.

PDU outlet mapping
Group C13/C19 loads by branch, hold 20% headroom per group, and lock phase balance at ±5% before the outlet map is frozen.

BBU runtime sizing
Ride-through seconds for generator handoff, or minutes for ordered shutdown — LFP capacity and C-rate decide which shelf you actually need.
Line page →
CRPS redundancy schemes
N, N+1 or N+N: what each costs in slots, copper and failure math — plus when 54V direct-to-rail beats 12V bus bars.

Busway ampacity planning
Run length, tap density and future growth set 250A vs 800A channel — plan splice points and feed drops before the ceiling closes.
Line page →OEM / ODM PARAMETERS
What you can change, per line.
Everything below is a program parameter, not a special favor — configured at pilot build and frozen into the test plan.
| Line | Electrical options | Mechanical options | Branding options | Docs |
|---|---|---|---|---|
| Rack PDU | Outlet mix, breaker rating, metering grade | 0U/1U, cord length 1.2–2.5m, color band | Laser logo, silk, retail box | Test report per serial |
| BBU | Capacity, C-rate, comms (CAN/PMBus) | RU height, cartridge count, cold-plate variant | Label silk, carton print | UN38.3 + MSDS pack |
| Supercapacitor | Module voltage, cell count, telemetry | 19"/23", housing color | Label silk | Cell COA + module report |
| CRPS PSU | Wattage, rail mix, fan curve, PMBus map | CRPS/mCRPS footprint, faceplate | Faceplate silk | Hi-pot + burn-in log |
| Busway | Ampacity 160–800A, tap metering | Run layout, splice/tap positions, finish | Channel stamping | Type-test certificate path |
HOW A PROGRAM STARTS
From RFQ to frozen spec.
Send the spec
Chassis drawing, outlet map, floor plan or a plain-English target — any of the four starts the engagement.
DFM in 48 hours
Engineering replies with feasibility notes, cost drivers and the two or three decisions that move price most.
Pilot & type test
First articles run the full QC gate; you keep the test log whether or not the program proceeds.
Freeze & ramp
Spec freezes, pilot run validates yield, mass production schedules against your deployment windows.
