AI-Powered supplier vetting
SummaryGuangzhou Expansuccess Technology Co., Ltd. is identified as a China-based trading company in the electrical and electronics sector, offering customized power-supply solutions. Its stated product range includes transformers, high-precision DC power supplies, load meters, communication power supplies, and frequency-conversion power supplies. The supplier reports four production lines, 6–10 quality-control staff, and specified annual capacities across four product categories. It also reports export activity, with 71%–90% of sales from exports and self-operated import/export rights. However, the available information does not substantiate certifications, after-sales service systems, financial credibility, customer cases, or staff experience; the stated total staff experience is zero. The supplied establishment date is 2026, while exporting reportedly began in 2016, creating an unresolved timeline inconsistency.
Supplier typeThe supplier is explicitly classified as a Trading Company and operates as a Limited Company in China. Its business identity and legal structure are stated, although the information does not establish whether it owns or directly operates all manufacturing resources.
R&D capabilityThe supplier states that it provides customized power solutions and tailor-made products for different industries and application scenarios, indicating product-solution development capability. However, no patents, R&D team details, technologies, or innovation results are provided.
Production capacityThe supplier reports four production lines, 6–10 quality-control staff, and stated annual capacities of 100,000 DC electric-load sets, 30,000 frequency converters, 50,000 telecom power-supply sets, and 50,000 programmable-power-supply sets. These figures explicitly support production capability, although the reported total staff experience is zero and no manufacturing-process details are supplied.
Customization capabilityThe company explicitly describes its core offering as customized power solutions and states that its product range is tailor-made for specific customer needs, industries, and application scenarios. This is direct evidence of customization capability, though no customization examples or project records are provided.
Product Q&A
Q:What is a Variable Frequency Drive (VFD)?
A:
A Variable Frequency Drive (VFD) is an electronic device used to convert the frequency of an input AC signal into a desired output frequency. It is typically used to regulate the speed of electric motors or to adapt power systems to meet varying voltage and frequency requirements.
Q:What is a transformer? How does it work?
A:
A transformer is an electrical device that transfers electrical energy between two or more circuits through the principle of electromagnetic induction. Depending on the requirements of the power system, it can step up (increase) or step down (decrease) voltage levels.
Q:What is an electronic load tester?
A:
An electronic load tester is a device used to simulate the operating conditions of a power supply or battery under actual load scenarios. It facilitates the testing of the performance of power supplies, batteries, and other electrical equipment under controlled conditions.
Q:What is a DC power supply?
A:
A DC power supply provides a stable output of Direct Current (DC) voltage. It is commonly used to power various electronic devices, charge batteries, conduct laboratory testing, and for other similar applications.
Q:Can all products be customized?
A:
Yes, customization is available; however, you will need to provide us with your detailed customization requirements.
