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:What is the biggest advantage of ADW300?

ADW300 has its built-in wireless communication module which allow it to realize 4G LTE, WiFi, NB-IoT, LoRa upstream communication without using extra IoT gateways. For the application scenarios when the meters can't be of centralized installation, ADW300 will usually be the best option for monitor 3-phase circuits that were far from each other.

Q:How should I deal with RS485 network communication malfunction?

First, check if the wiring of RS485 communication line was loosen or wired incorrectly.(like reversely wiring the A,B terminal). Next,inspect if the meter's setting of address, baud rate, check bit was correct by using keypads on the meter.

Q:What if LoRa communication of meters malfunctioned?

First, use USB to RS485 serial converter to connect the meter with computer. Then use adjustment software to check if setting of meter is on consensus with the setting of master station.(setting of channel and spreading factor--SF) If setting remain the same, then it might be due to large interference of work site or the excessively far range between meter and host. In that case, it's recommended to use chuck antenna or set a new master station nearby.

Q:What's the difference between ADW300 and ADW300W

ADW300 has internal current transformers and can select compatible current transformer according to the site current to realized a secondary connection via CTs. ADW300W on the other hand, has external current transformers.(non-detachable or it will damage the meter) This kind of design extremely ease the wiring and installation if the work-site already has CTs.
