Buyer pains we hear most

  • Per-unit calibration accuracy across temperature is hard to maintain
  • Isolation barrier failures are catastrophic
  • MID metrology alignment requires documented calibration chain
  • High-current PCBA needs careful thermal design and AOI

Typical product traits

  • Current shunt or CT-based sensing front end
  • Mains isolation barrier with reinforced creepage and clearance
  • High-current trace routing on copper-heavy boards
  • Display, communication, and pulse output options

Regulatory environment

Static meters for active energy

IEC 62053-21 / -22

Measuring Instruments Directive

2014/32/EU (MID)

Low Voltage Directive

2014/35/EU

Test plan considerations

  • Per-unit current shunt or CT calibration
  • Hipot isolation test on every unit
  • Linearity check across declared accuracy range
  • Documented calibration chain to traceable reference

Frequently asked questions

Do we need a written test plan?

Yes. A production test plan defines pass and fail criteria, FCT vectors, calibration steps, and serialization rules. We help draft one if your team has not written one yet, based on your firmware behavior and target field performance.

Do you support RoHS and REACH compliance?

Yes. We work with RoHS-compliant component selection and SAC305 lead-free solder by default. REACH substance documentation comes from supplier declarations forwarded with each batch.

Do you manage component sourcing?

Yes. We work from your approved vendor list (AVL) or build one with you, including dual-source identification for lead-time risk. We flag obsolete or long-lead parts during DFM review and propose alternates when needed.
