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:What is the maximum output current and voltage?

The device outputs 30A/phase current and 125V/phase voltage. Parallel connection achieves 180A current, and 3-phase parallel current reaches 120A.

Q:Does the tester support synchronous testing across different locations?

Yes, it features a GPS synchronous testing function with an embedded synchronization card, allowing two testers in different places to exchange data via RS232.

Q:What operating system does the host machine use?

The host machine runs independently with an embedded high-performance IPC, 128M memory, and the Windows XP operating system.

Q:Can this tester be used for modern microcomputer-based protective devices?

Yes, it tests traditional relays and modern microcomputer-based devices, specifically excelling in transformer differential protection and standby power supply switching.

Q:What are the frequency and harmonic capabilities?

The fundamental frequency range is 20-1000Hz, and it supports harmonic time from 1-20 with an output precision of 0.5 degree.
