AI-Powered supplier vetting

SummaryThe supplier demonstrates broad customization and R&D service capabilities, including OEM and ODM services, customization from samples and designs, and full or minor customization. It reports 10 production lines, 6–10 quality-control staff, defined finished-product inspection instructions, and lead times within 15 working days in both peak and off-season periods. The supplier holds ISO9001:2015 and CE-related certification evidence and reports high-tech products with independent intellectual property rights. However, it has no valid manufacturing-capacity contract with related subcontractors, no inventory, overseas warehouse, overseas showroom, overseas agents or branches, or overseas service countries, and it has not participated in offline trade shows. Financial information is only represented by year labels, so financial credibility cannot be fully assessed.

Supplier typeThe supplier appears to be a manufacturer with dedicated R&D, production, QC, procurement, sales, service, and HR departments, operating 10 production lines and producing electronics and automation-related products. Its reported independent intellectual property and production organization support classification as an original equipment/manufacturing supplier rather than only a trading intermediary.

CertificationsThe supplier reports an ISO9001:2015 certificate and CE capability for products. These are explicit certification-related credentials, although the slices do not provide certificate validity dates, scope, or issuing-body details.

R&D capabilityThe supplier reports high-tech products based on electronics and automation, independent intellectual property rights, OEM and ODM capabilities, and broad design-service options. Conversely, it reports no available SDK and no new products during the past year, so the evidence supports established technical capability but not clearly sustained recent innovation.

Production capacityThe supplier reports 10 production lines, 6–10 QC staff, product output examples of 400 pieces for each of five listed tester categories, standardized finished-product inspection instructions, and lead times within 15 working days year-round. However, it has no valid manufacturing-capacity contract with related subcontractors, so subcontracting capacity and contractual production assurance are weaknesses.

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

Client casesThe supplier states that it has provided OEM services to well-known brands and that its products have operated successfully in power, transportation, security, and other fields. These are customer and application references, but no customer names, project details, contract evidence, or independently verifiable case studies are supplied.

Product Q&A

Q:What protection functions can this tester verify?

It tests AC relay action values, low voltage microcomputer line protection (overcurrent, zero sequence), high voltage line protection, and microcomputer transformer differential protection.

Q:Can the device simulate multiple fault states?

Yes, it supports up to 5 states, simulating re-closing acceleration, single grounding, two-grounding, interphase short circuit, and three-phase short circuit.

Q:How long does the battery last during normal use?

The built-in 20Ah lithium battery provides approximately 8 hours of normal operation time.

Q:Is the device portable and easy to carry?

Yes, it is a hand-held unit weighing less than 2.75kg with dimensions of 255x210x78mm.

Q:What is the response time for voltage and current changes?

The rise and fall time for both voltage and current is less than 100 microseconds.
