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's the difference of current input via direct connect or via CTs?

Normally, for 3-phase loads with rated current below 80A AC, we will use model of ADL400 whose current input is via direct connect. Specs of 'Rated Current: 10(80)A AC' was aimed for this model of ADL400 (current input via direct connect). 10 means basic current is 10A AC, 80 means rated current input is 80A AC. And for 3-phase loads with rated current over 80A AC, we will use model of ADL400 whose current input is via CTs (usually paired with -/5A CTs whose secondary current output is with 5A A

Q:How can I set the CT or PT ratio of ADL400?

Current ratio of ADL400 could be set by using the keypads on ADL400 and following the instruction of ADL400 manual. Also, setting need to be according to the CTs or PTs ratio which were paired with ADL400. For example, if the current input is via 250A/5A CTs, the CT ratio on ADL400 should be set to 250/5=50. And if the voltage input is via direct connect, PT ratio on ADL400 should be set to 1. When the problem hasn't been solved, please contact us for help.

Q:Could ADL400 be used in IoT Energy Monitoring System for factory or building?

ADL400 has standard RS485 interface and MODBUS-RTU communication protocol which allow it to be integrate with our IoT Energy Monitor Solution that can enable our users to remotely check all the data collect by energy meters like ADL400 on their mobile phone or PC. For more information, please Contact us or check in IoT Energy Monitoring Solution Introduction.

Q:What is Multi-rate/tariff function? How does it work?

First,multi-rate/tariff function was designed to be used for billing system. Second, the electricity price of different time duration in a day is different in some country. Energy meter with this function can measure the kwh data and assign them to several time duration in a day and put a label of spike/peak/flat/valley kwh on them respectively. And if such energy meter was connected to the billing system by using a IoT gateway, it can send the kwh data of different time duration which was with
