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:How to set the CT and PT ratio of the protection device?

The protection device can set the CT and PT ratio through the fixed value menu. For example, the current transformer is 75/5 and the voltage transformer is 10/0.1, then the CT ratio is set to 15 and the PT ratio is set to 100.

Q:For AM5, if you want to place single circuit protection and transformer protection, how to distinguish the model?

AM5-F is suitable for line protection and transformer protection.No need to distinguish between models when placing orders

Q:When the voltage is a three-phase three-wire system, does the current have to be connected with 2CT?

The voltage wiring mode and current wiring mode of the protection device can be set independently, and can be connected freely.

Q:How to confirm whether the anti-trip function is configured?

If the circuit breaker is equipped with anti-trip, the device does not must be equipped with anti-trip; if the circuit breaker does not have anti-trip, you need to configure the AM5-FT anti-trip module. (If DC48V is selected as the operating power supply, the anti-trip box is not optional, and the circuit breaker must be equipped with anti-trip function; if you choose AC anti-trip, please note that AC and DC general anti-tripping)

Q:How to purchase suitable protection devices?

Before ordering, it is recommended to consult related engineers, select the appropriate protection model, and then fill in the corresponding selection table, and place the order after confirmation by the engineers.
