AI-Powered supplier vetting

SummaryWenzhou Yuanda Electrical Equipment Co., Ltd. is a China-based manufacturer established in 1993, with 280 employees, more than 10 production lines, 50 quality-control staff, and stated output capacities for voltage stabilizers, miniature circuit breakers, and AC contactors. The supplier reports ISO 9001:2015 certification and product certifications including UL, CE, and 3C, as well as design patent technology. Its stated processes include advanced design software, testing equipment, and controls from raw-material procurement through finished products. However, the available information does not verify contract manufacturing, inventory, overseas services, ODM/OEM, SDK, environmental, or fire-drill capabilities. No customer cases or financial-strength evidence is provided. The audit record identifies TUV Rheinland and a valid report period, but the audit result is recorded as “0” without an explained interpretation.

Supplier typeThe supplier is explicitly identified as a manufacturer and a limited company located in Zhejiang, China. It has operated since 1993, supporting classification as an established manufacturing supplier.

CertificationsThe supplier reports ISO 9001:2015 certification and product certifications including US UL, EC CE, and 3C; it also states that it has held an industrial production permit and received export-advanced-enterprise recognition for three consecutive years. A TUV Rheinland audit report is listed with dates from November 4, 2025 to November 3, 2026, although the recorded audit result of “0” is not explained.

After-Sales capabilityThe supplier states that its marketing center provides comprehensive pre-sale, in-sale, and after-sale service to customers worldwide. However, overseas warehouse, showroom, and overseas agent or branch capabilities are all marked unknown, so the depth and delivery model of after-sales support cannot be fully verified.

R&D capabilityThe supplier reports using PROE/CAD and other design software, integrating decades of low-voltage electrical manufacturing experience, and holding product design patent technology. ODM, SDK, private-mold, 3D-design, and new-product R&D capabilities are marked unknown, limiting confirmation of broader innovation services.

Production capacityThe supplier reports more than 10 production lines, 50 quality-control staff, and stated annual capacities of 1,000,000 voltage-stabilizer boxes, 5,000,000 miniature circuit-breaker boxes, and 2,000,000 AC-contactor bags. It also describes testing equipment and process controls from raw-material procurement through finished production, providing explicit evidence of substantial production and quality-control infrastructure.

Product Q&A

Q:What is a voltage stabilizer and how does it work?

A voltage stabilizer is an electrical device that automatically maintains a constant voltage level to protect equipment from power fluctuations. It works by detecting input voltage variations and using transformer-based technology to deliver stable output voltage through automatic buck/boost operations.

Q:What's the difference between a voltage stabilizer and a UPS?

While both provide power protection, stabilizers focus solely on voltage regulation, whereas UPS systems provide battery backup during power outages. Stabilizers don't have batteries but offer continuous voltage correction while power is available.

Q:How do I choose the right capacity stabilizer for my equipment?

Calculate the total wattage of all devices to be protected, add 20-30% safety margin, and choose the next higher standard rating. For motor-based equipment (like AC units), select a stabilizer with 3-4 times the rated power to handle startup surges.
