Use case
Energy Monitoring Device Manufacturing
A three-phase energy monitor with current shunt or CT input. Volume 200 to 1500 units per batch. Each unit calibrated at the factory against a traceable reference, calibration data stored on board, calibration certificate generated.
Typical BOM characteristics
- High-current shunt or CT interface
- Reinforced isolation barrier
- Metrology IC or analog front end with high-resolution ADC
- Display, communication, or pulse output
Test plan example
- Hipot isolation test
- Per-unit calibration at three reference loads
- Linearity verification across declared range
- Calibration data write and read-back
- Calibration certificate generation per unit
Box-build scope
- PCBA into DIN-rail housing
- Terminal blocks for current and voltage inputs
- Label with model, serial, calibration date
- Pack with calibration certificate
Lead-time pattern
10 to 12 weeks NPI, 5 to 6 weeks repeat batch
