AI-Powered supplier vetting

SummaryThe supplier is a technology-driven enterprise integrating R&D, production, sales, and after-sales service, offering electrical testing equipment, specialized tools, meters, and related products. It reports new products within the past year, ODM capability, broad customization options, and OEM service for well-known brands. Overseas service is stated for Vietnam and Russia, including installation, debugging, maintenance, repair, and training, but the supplier has no overseas warehouses, showrooms, agents, or branches and has not participated in offline trade shows. Quality assurance and raw-material traceability are reported, while several service-control procedures lack written records. Financial information is inconsistent and insufficient for assessment.

Supplier typeThe supplier identifies as a technology-driven enterprise integrating R&D, production, sales, and after-sales service. Its listed products include electrical tools, intelligent meters, energy measurement equipment, fault-location and cable-testing equipment, and specialized instruments, indicating a manufacturer-oriented technology supplier.

After-Sales capabilityThe supplier states that it provides after-sales service and offers installation, debugging, maintenance, repair, and training in Vietnam and Russia. However, it has no overseas warehouse, showroom, agent, or branch, has not participated in offline trade shows, and its complaint-handling and service corrective-action procedures have no written records, limiting evidence of formal service execution controls.

R&D capabilityThe supplier reports R&D capability, new products within the past year, ODM services, and integration of R&D with production and after-sales service. It does not have an available SDK, but the available evidence still explicitly supports product-development capability.

Production capacityThe supplier is described as integrating production with R&D, sales, and after-sales service, and it lists a broad product range including tools, meters, and testing equipment. Quality assurance and raw-material traceability are reported, but the slices do not provide production capacity, factory scale, or output data.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also reports ODM service, providing direct evidence of broad customization capability.

Product Q&A

Q:What is the main function of the NRB300 Transformer Turns Ratio Tester?

It performs automatic variable ratio measurement, completing three-phase ratio, winding wiring, and group label measurement with one press, including ratio error calculation.

Q:What transformer combinations can this tester measure?

It measures Y/y, Y/d, D/y, D/d, ZN/y, ZN/d combinations, and handles unknown group transformers by measuring high and low side wiring.

Q:How does the tester handle high excitation currents?

When excitation current is large, the output voltage automatically reduces to meet the requirements of low rated voltage and large excitation current transformers.

Q:Does the device have data storage capabilities?

Yes, it features built-in power-down memory and a micro-printer to preserve and print measurement data long-term.

Q:What is the ratio measurement accuracy?

Accuracy is 0.1% for ranges 0.8-1000, 0.2% for 1000-2000, and 0.5% for 2000-10000.
