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's the biggest advantage of ADW300?

ADW300 has its built-in wireless communication module which allow it to realize 4G LTE, WiFi, NB-IoT, LoRa upstream communication without using extra IoT gateways. For the application scenarios when the meters can't be of centralized installation, ADW300 will usually be the best option for monitor 3-phase circuits that were far from each other.

Q:How should I deal with RS485 network communication malfunction?

First, check if the wiring of RS485 communication line was loosened or wired incorrectly.(like reversely wiring the A,B terminal). Next, inspect if the meter's setting of address, baud rate, check bit were correct by using keypads on the meter.

Q:What if LoRa communication of meters malfunctioned?

First, use USB to RS485 serial converter to connect the meter with computer. Then use adjustment software to check if setting of meter is on consensus with the setting of master station. (setting of channel and spreading factor--SF) If the setting remains the same, then it might be due to large interference of work site or the excessively far range between meter and host. In that case, it's recommended to use chuck antenna or set a new master station nearby.

Q:What's the difference between ADW300 and ADW300W

ADW300 has internal current transformers and can select compatible current transformers according to the site current to realize a secondary connection via CTs. ADW300W on the other hand has external current transformers.(non-detachable or it will damage the meter) This kind of design extremely eases the wiring and installation if the work-site already has CTs.
