| # Data Centre Nameplates |
|
|
| **Read an equipment nameplate and know if it is the unit the schedule asked for.** |
|
|
| Photograph the nameplate of a UPS, PDU, switchgear, generator, transformer, busway, battery, CRAH or chiller. This |
| runs OCR in your browser, pulls out the plate's fields — manufacturer, model, serial, voltage, phase, Hz, kVA, kW, |
| amps, MCA, MOCP, refrigerant, manufacture date — and **checks each one against the equipment schedule**, flagging |
| a mismatch instead of a silent pass. It builds an asset register and exports it to CSV. |
|
|
| Nothing is uploaded: the photo and the schedule stay on your device. |
|
|
| ## Try it |
|
|
| 1. Drop an equipment schedule as CSV (or click **Use sample schedule**). |
| 2. Drop a nameplate photo (or click **Try a sample nameplate**). |
| 3. Click **Read nameplate** and check the verdict, field by field, against the plate. |
|
|
| ## How it works |
|
|
| - **OCR** — `tesseract.js@5` (English LSTM), loaded from a CDN, plus an error model for the way OCR misreads plate |
| lettering (serifed `V`→`Vv`, `K`→`X` in `KVA`, `HZ`→`Hw`, codes split after their punctuation). |
| - **Extraction** — labelled-field parsing of `MODEL`, `S/N`, `MVA`, `MCA`, `MOCP`, `FLA`, `VOLTS`, `REFRIGERANT`, |
| `MFG DATE`, with voltages read as `480Y/277`, `13.8 kV` or `208/120`. |
| - **Matching** — model and serial codes compared with `O/0`, `I/L/1`, `S/5`, `B/8`, `Z/2` folded, so a misread is |
| not a false mismatch while a genuine voltage variant still fails. |
