AI-Powered supplier vetting

SummaryThe supplier demonstrates documented service-control procedures, complaint-handling processes, quality assurance, manufacturing coordination, and finished-product inspection instructions. It offers broad customization, ODM and OEM services, recent product development, multiple engineering tools, SDK availability, and digital ERP-based process management. Manufacturing and export capabilities are supported by SMT, assembly, and automated processing lines, in-stock capacity, valid subcontractor contracts, and self-operated import/export rights. Overseas agents or branches and trade-show participation are reported, but no overseas warehouse or showroom is available, and the stated overseas-service country count is zero. Evidence is insufficient to confirm certifications, financial credibility, or specific customer cases.

Supplier typeThe supplier operates or coordinates SMT, assembly, and automated processing lines, maintains valid manufacturing contracts with associated subcontractors, has inventory capacity, and holds self-operated import/export rights. It also reports overseas agents or branches and participation in MEE Middle East Energy, indicating a manufacturing-oriented supplier with international service exposure.

After-Sales capabilityThe supplier has documented and followed procedures for corrective and preventive actions, customer complaints, and service-capability assessment. It accepts multiple quotation and payment terms, reports lead times within 15 working days in both peak and off-season, and has overseas agents or branches; however, no overseas warehouse or showroom is available and the stated overseas-service country count is zero.

R&D capabilityThe supplier reports new products during the past year, ODM capability, SDK availability, R&D engineers responsible for new-product development and production support, and design tools including AutoCAD, Pro/E, and SolidWorks. It also maintains auditable design documentation and uses ERP for digital management, providing explicit evidence of structured innovation and development capability.

Production capacityProduction capability is supported by SMT, assembly, and automated processing lines, uniformly followed finished-product inspection instructions, inventory capacity, valid contracts with associated subcontractors, and documented service-capability procedures. Export activity is reported at 41%–50% of total sales, and peak- and off-season lead times are both within 15 working days.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. The same broad customization coverage is reported across both R&D and design-service information, supported by ODM capability and engineering design tools.

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).

Q:What are the optional modules available?

Optional modules include MD82 (8DI+2DO), MA84 (8AI+4AO), MLOG (TF card), MCM (RS485), MCE (Ethernet), MCP (Profibus-DP), and temperature sensors.

Q:What is the warranty period?

The product comes with a 2-year warranty.
