AI-Powered supplier vetting

SummaryThe supplier operates in power testing products and related electronic, electrical, machinery, software, and information-system activities. It reports 3D design, ODM, OEM, SDK, new-product, and broad customization capabilities, with stated annual productivity of 1,500 sets for four listed testing-equipment categories. Procedures and records exist for corrective/preventive actions and customer complaints, while the supplier explicitly reports no quality assurance in quality-control processes. It has valid manufacturing contracts with associated subcontractors, but no in-stock capacity, overseas warehouse, or overseas showroom. Overseas service offerings include installation, debugging, maintenance, repair, and training, although the stated number of countries served overseas is zero. Financial evidence is incomplete and includes zero values for the listed 2024 financial metrics, so credibility cannot be established from the provided data.

Supplier typeThe supplier is positioned in the power-testing and electrical-equipment sector, with stated activities covering electronic products, software and auxiliary equipment, machinery, instruments, communication equipment, and professional design services. Its company description specifically presents one-stop power testing products and services.

After-Sales capabilityThe supplier has documented and followed procedures for corrective/preventive actions and customer complaints, and lists installation, debugging, maintenance, repair, and training services. However, it reports no overseas warehouse or showroom and zero countries where overseas services are offered, indicating limited demonstrated overseas coverage.

R&D capabilityThe supplier reports new products during the past year, ODM service, OEM service for popular brands, 3D software design, and an available SDK. These are explicit indicators of product-development and technical integration capability.

Production capacityAnnual productivity is stated as 1,500 sets each for four categories of high-voltage and related testing equipment, supported by listed machining, drilling, milling, welding, cutting, and wire-winding facilities. Valid manufacturing contracts with each associated subcontractor are also reported, although no in-stock capacity is available.

Customization capabilityThe supplier explicitly offers customization from samples and designs, full and minor customization, flexible customization, and 3D software design services. The same broad customization range appears in both its R&D and production-related information.

Product Q&A

Q:Can this tester operate independently without a computer?

Yes, the host machine features an embedded high-performance IPC with Windows XP, allowing it to run independently with its own screen and controls.

Q:Is GPS synchronization supported for remote testing?

Yes, the device has an embedded GPS synchronous testing function that allows synchronized testing by exchanging two testers in different places.

Q:What types of relays can this device test?

It tests traditional relays, protective devices, and modern microcomputer-based protective devices, especially transformer differential protection and standby power supply switching.

Q:What is the accuracy grade of the measurement?

The accuracy grade is 0.5, with a time measuring range of 0.1ms to 9999s and measurement accuracy of less than 0.1ms.

Q:Does the device support DC voltage output?

Yes, it provides independent special DC auxiliary voltage sources of 110V (1A) and 220V (0.6A) for DC relay or protective devices.
