AI-Powered supplier vetting

SummaryThe supplier manufactures and sells power transmission, distribution, control, charging-station, power-electronic, and photovoltaic equipment. It demonstrates broad customization and ODM/OEM capabilities, reports new-product development during the past year, and has SDK availability. Quality processes include seven inspectors, documented finished-product inspection instructions, traceability, quality assurance, complaint procedures, and corrective-action procedures. Production information indicates five lines and lead times within 15 working days in both peak and off-peak seasons. Overseas support is limited: no overseas warehouse, showroom, agent, or branch is reported, although the supplier has attended Middle East Energy Dubai and serves multiple export markets. Financial credibility cannot be assessed from the non-financial information provided.

Supplier typeThe stated business scope covers manufacturing and sales of distribution and control equipment, charging stations, power-electronic components, and photovoltaic equipment. The supplier also reports OEM service for well-known brands, indicating a manufacturer with OEM capability rather than a pure trading profile.

After-Sales capabilityThe supplier has a documented and followed customer-complaint procedure and has attended an overseas trade show. However, it reports no overseas warehouse, showroom, agent, or branch, and the number of overseas service countries is stated as zero, limiting evidence of localized after-sales support.

R&D capabilityThe supplier reports new-product development in the past year, ODM services, SDK availability, one national science and technology progress award, and two years of total R&D engineer experience. These indicators support innovation activity, although the limited stated R&D experience prevents assessing its depth comprehensively.

Production capacityThe supplier reports five production lines, multiple listed manufacturing and assembly facilities, seven quality inspectors, and lead times within 15 working days in both peak and off-peak seasons. These explicit indicators support operational production capability, although output scale is not assessed here because the provided output figure is monetary.

Customization capabilityBoth R&D and design-service records list customization from samples, designs, full customization, minor customization, and flexible customization. The supplier also reports ODM service, providing explicit evidence of broad customization capability.

Product Q&A

Q:What is the control power supply voltage of the SKT Series ATS?

The standard control power supply voltage is AC220V. Optional voltages include AC110V, AC208V, AC280V, AC180-280V, DC24V, DC12V, and DC48V (optional for 250A and below).

Q:Can the SKT Series ATS work with generators and solar inverter systems?

Yes. The SKT Series ATS is widely used in generator backup systems, solar energy systems, and other dual power applications requiring automatic source transfer.

Q:Does the ATS require a neutral wire (N) for operation?

It depends on the control voltage configuration and local power system. For standard AC220V control power, correct voltage between terminals is required. In some systems, L+L can also be used if the voltage meets the ATS control requirement.

Q:What happens if both power sources fail?

For the 3-position type ATS (I-0-II), the switch can automatically transfer to the OFF (0) position when both power sources are unavailable, improving system safety for fire-fighting or maintenance applications.

Q:Does the ATS include mechanical and electrical interlock protection?

Yes. The ATS is designed to prevent simultaneous connection of two power sources, ensuring safe and reliable transfer between main and standby power.
