AI-Powered supplier vetting

SummaryThe supplier demonstrates broad electrical, power-electronics, automation, IoT, software, and related equipment business coverage. It has documented procedures for corrective and preventive actions, complaint handling, supplier-service assessment, and finished-product inspection. Its capabilities include 3D software design, ODM, SDK provision, new-product development, extensive customization, SMT/DIP production, automated sensing, debugging, and testing. Overseas support is available through agents or branches in Singapore, including installation, training, repair, maintenance, and debugging. However, the supplier has no reported in-stock capacity, overseas warehouse, overseas showroom, or valid manufacturing-capacity contract with related subcontractors. Evidence is insufficient for certification holding and customer cases.

Supplier typeThe stated business scope covers electrical signal equipment, power-electronic components, instruments and meters, software, intelligent equipment, lighting, IoT and information-security devices, charging stations, power-distribution control equipment, and industrial automation systems. Its facilities include SMT and DIP assembly lines plus automatic sensing, debugging, and testing equipment, indicating a manufacturer and technical equipment supplier rather than a purely trading-oriented entity.

After-Sales capabilityThe supplier has documented complaint-handling and corrective/preventive-action procedures with records, and overseas service capability through agents or branches in Singapore covering installation, training, repair, maintenance, and debugging. However, it reports no overseas warehouse and no overseas showroom; these are logistical limitations but do not negate the documented service functions.

R&D capabilityThe supplier provides 3D software design, ODM, SDK access, and multiple forms of customization, and reports new products during the past year. Nevertheless, it states that it has not established an AI model for big-data processing and decision-enabled management, which is a stated sustainability and digital-management gap rather than proof of insufficient product innovation.

Production capacityProduction evidence includes SMT and DIP assembly lines, automatic electricity-sensor production, and automatic debugging and testing equipment; finished-product inspection instructions are uniformly followed. Lead times are stated as within 15 workdays in both peak and off-seasons, but the supplier reports no in-stock capacity and no valid manufacturing-capacity contract with related subcontractors, limiting evidence of flexible or backup capacity.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, flexible customization, 3D software design, and ODM services. These combined statements provide direct evidence of broad customization and design-development capability.

Product Q&A

Q:How is the ACR10R series installed?

This series of meters adopts din rail installation, which can be easily and quickly installed in the user's metering box.

Q:How does the ACR10R series collect current?

This series of meters use a split core CT to measure current, and is convenient and quick to install. The maximum support is 300A (transformer), 20000A (Rogowski coil).

Q:What is the working principle of the counter current meter?

The counter current detection meter needs to be used with inverter, and the inverter reads the current and direction collected by the meter through RS485 communication in real-time and adjust output power, to achieve anti-backflow function.

Q:What is the refresh speed of the electricity meter data?

250ms.

Q:Does the meter support connecting multiple inverters?

The inverter can collect the same meter data through the data collection(gateway). This function requires the inverter manufacturer to debug IF you place an order directly,please make sure to note the required technical parameters in the remarks IF you have any other requirements,please contact me/.
