Hardware · PCB
HWWe design mixed-signal boards for metering front-ends and power electronics, balancing accuracy, isolation, and cost for high-volume utility hardware.
WHY IT MATTERS Metering accuracy and field survival start at the board.
ENGINEERING
One discipline across power, data, and grid hardware.
Archai engineers grid-edge electronics as a single system — metering and AMI, PV power electronics, sensing, and MV distribution share one requirement-to-field engineering basis. Every design carries traceable evidence from specification through verification to deployment.
01 / DISCIPLINES
Eight disciplines, one basis.
Embedded firmware
FWReal-time metering and control firmware with secure boot and field-updatable images, built for years of unattended operation.
WHY IT MATTERS The meter must stay correct and serviceable long after install.
AMI communication
COMMSDLMS/COSEM stacks over PLC and RF-mesh, interoperable with head-end systems and utility programs.
WHY IT MATTERS Data only has value when it reaches the head-end reliably.
Metrology · calibration
CALAccuracy-class metering design paired with in-house calibration benches and traceable references.
WHY IT MATTERS Billing-grade measurement is non-negotiable.
Reliability · environment
RELEnvironmental, ingress, thermal, surge, and EMC engineering for outdoor and substation life.
WHY IT MATTERS Grid-edge hardware lives in the weather and on the line.
Mechanical · enclosure
MECHWe engineer housings, sealing, and mounting systems for outdoor and substation environments, designed together with the electronics they protect.
WHY IT MATTERS The enclosure is the first line of defence in the field.
Cyber · device security
SECSecure boot, device key management, and DLMS/COSEM security suites across the metering fleet.
WHY IT MATTERS Grid devices are infrastructure — security is part of correctness.
Edge software · HES/MDMS
SWHead-end and meter-data interfaces plus device provisioning and diagnostics tooling.
WHY IT MATTERS Deployment and operations need software as disciplined as the hardware.
02 / PROCESS
From requirement to field.
Four stages, each closing with a versioned deliverable tied to the design revision.
01DefineRequirements, interfaces, hazards, and field realities.→ SPEC
02DevelopElectronics, firmware, mechanics, and connected tooling.→ DESIGN
03ProveVerification against electrical and environmental limits.Every platform is verified against its electrical accuracy class and environmental envelope; results are captured as a versioned V&V report tied to the design revision, so field behaviour traces back to evidence. [ CONFIRM TEST ITEMS / STANDARD NUMBERS ]→ V&V REPORT
04DeployManufacturing transfer, field support, and lifecycle care.→ HANDOFF
03 / STANDARDS & COMPLIANCE
Designed to recognised standards.
Archai designs to recognised regional and protocol standards and maintains hardware compliance across its markets.
