AI-Powered supplier vetting

SummaryThe supplier demonstrates established product development and customization capabilities, including 3D design, ODM services, SDK availability, and new product development within the past year. Production-related evidence includes SMT, DIP, automatic sensor production, debugging, and testing equipment, with documented finished-product inspection. Service management procedures exist for supplier assessment, corrective and preventive actions, and complaint handling. Overseas support is available through agents or branches in Singapore, including installation, training, repair, maintenance, and debugging. However, the supplier has no stated in-stock capacity, overseas warehouse, overseas showroom, or valid manufacturing-capacity contract with related subcontractors. Evidence of certification ownership, customer cases, and financial credibility is insufficient. The supplier also reports no established AI model for big-data-enabled management.

Supplier typeThe supplier’s stated business scope covers electrical signal equipment, power electronic components, electrical and intelligent instruments, lighting, IoT and information-security devices, charging stations, power-distribution control equipment, industrial automation systems, and related electrical equipment. Its facilities include SMT, DIP, sensor production, automatic debugging, and testing lines, indicating a manufacturer and technical equipment supplier rather than only a trading intermediary.

After-Sales capabilityThe supplier has documented procedures and records for corrective and preventive actions, customer complaints, and supplier-service assessment. It also provides overseas installation, training, repair, maintenance, and debugging through overseas agents or branches, including service coverage in Singapore; however, no overseas warehouse or showroom is available.

R&D capabilityThe supplier offers 3D software design, multiple forms of customization, ODM services, and an available SDK, and it reports new product development during the past year. Conversely, it states that it has not established an AI model for big-data processing and management decision enablement; this limits evidence of advanced digital innovation but does not negate its documented product-development capabilities.

Production capacityProduction evidence includes SMT, DIP, automatic electricity-sensor production, automatic debugging, and testing equipment, with written instructions uniformly followed for finished-product inspection and stated peak- and off-season lead times within 15 workdays. Capacity-related limitations include no in-stock service capacity and no valid manufacturing-capacity contract with related subcontractors.

Customization capabilityThe supplier explicitly supports customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also provides 3D software design and ODM services, directly supporting broad product-design and customization requirements.

Product Q&A

Q:What's 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.

Q:What is the warranty period?

We provide a comprehensive 2-year warranty for all our mechanical equipment.
