AI-Powered supplier vetting

SummaryThe supplier demonstrates broad customization and R&D capabilities, including ODM, OEM, SDK availability, multiple design tools, and documented design review, verification, and validation records. Production-related evidence includes SMT, assembly, and automated processing lines, inventory capacity, contracts with associated subcontractors, and standardized finished-product inspection instructions. Service management is supported by written procedures and records for corrective actions, complaints, supplier assessment, and quality assurance. The supplier has overseas agents or branches, export rights, and prior participation in MEE Middle East Energy, but reports no overseas warehouse or showroom and lists zero countries offering overseas services. Financial credibility cannot be assessed because only years are provided, without non-financial supporting results. No explicit certification holdings or customer case details are provided.

Supplier typeThe supplier operates or coordinates SMT, assembly, and automated processing facilities, maintains inventory capability, and has valid manufacturing contracts with associated subcontractors. It also holds self-operated import/export rights and has overseas agents or branches, indicating a manufacturing-oriented supplier with international service arrangements.

After-Sales capabilityThe supplier has documented and followed procedures for corrective and preventive actions, customer complaints, service-capability assessment, and quality assurance. Overseas agents or branches and prior participation in an offline trade show support service reach, while the absence of overseas warehouses and showrooms limits the evidence for localized after-sales infrastructure.

R&D capabilityThe supplier reports new products during the past year, ODM services, SDK availability, R&D responsibilities covering new-product development and production technology support, and use of AutoCAD, Pro/E, and SolidWorks. It also maintains auditable design input, output, review, verification, and validation documentation, supporting a demonstrated product-development process.

Production capacityProduction evidence includes SMT, assembly, and automated processing lines, standardized finished-product inspection instructions, inventory capability, valid contracts with associated subcontractors, and lead times within 15 workdays in both peak and off-seasons. These stated capabilities support a positive assessment of manufacturing and delivery readiness.

Customization capabilityThe supplier explicitly provides customization from samples, customization from designs, full customization, minor customization, and flexible customization. The same broad range is reported across R&D and design-service capability records, indicating substantial customization coverage.

Product Q&A

Q:What communication protocols are supported?

The meter supports RS485 with Modbus-RTU and DLT645 protocols, RJ45 Ethernet with Modbus-TCP, HTTP, and DHCP, as well as Profibus-DP interface.

Q:Can the meter be customized?

Yes, customization is available for phase (3p3l/3p4l), accuracy (0.2s/0.5s), rated voltage, rated current, frequency, analog inputs/outputs, and protocols.

Q:What is the measurement accuracy?

The accuracy classes are 0.5s and 0.2s for voltage, current, power, and active power. Reactive power is class 2, and harmonics are 1% (2nd-42nd) and 2% (43rd-63rd).
