How long does delivery take?

Standard products take 10-15 working days. New customizations require an additional 5-7 days for samples. Large orders may take 15-30 days.

Can samples be provided and how are they charged?

Samples are available for serious customers. A sample fee is usually required but can be refunded or deducted after a bulk order. Lead time is 3-5 days.

What causes transformer failure and is there a warranty?

Failures are often due to overload, short circuits, or harsh environments. We provide a 1-year warranty covering free repair or replacement for quality issues.

AI-Powered supplier vetting

SummaryHANGZHOU UDWELLS TECHNOLOGY CO. Ltd. was founded in 2008 and reports a self-built plant exceeding 15,000 square meters, more than 10 production lines, Europe as a primary export market, and peak-season order fulfillment within 15 working days. It provides multiple customization options, ODM services, and has launched new products within the past year. The supplier also reports OEM service for well-known brands and quality assurance in its quality-control processes. However, no R&D audit documentation, SDK, approved-supplier list, written service procedures, corrective/preventive-action procedures, or complaint-handling procedures were available. Overseas warehouses, showrooms, agents or branches, and offline trade-show participation were not reported. Financial information is insufficient for a credibility judgment, and sustainability-related fire-drill and environmental-assessment status is unknown.

After-Sales capabilityTechnology engineers are responsible for technical support during production and after-sales service, but the supplier has no written procedures or records for effective service assessment, corrective and preventive actions, or customer complaint handling. It also has no overseas warehouse, showroom, agent, or branch, limiting evidence of structured or localized after-sales support.

R&D capabilityThe supplier reports new products within the past year, ODM capability, customization-related R&D services, and use of PS and CAD. It also reports OEM service for well-known brands. Countervailing evidence includes only one year of total R&D engineer experience, no available SDK, and no R&D design-input, output, review, verification, or validation documents for audit.

Production capacityThe supplier reports a self-built plant exceeding 15,000 square meters, more than 10 production lines, complete testing facilities, and peak-season order fulfillment within 15 working days. These explicit operating-scale and delivery statements support a production-capability advantage, although the number of quality-control staff is listed as unavailable.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, flexible customization, and minor customization. It also provides ODM services, demonstrating broad stated customization coverage.

Client casesThe supplier states that it provides OEM services for well-known brands and identifies Europe as a primary export market. These statements indicate some brand and export experience, but no customer names, project details, order references, or verifiable case documentation are provided.

Product Q&A

Q:What specifications are needed for production?

Please provide Input Voltage (with fluctuation range), Output Voltage and Current, Rated Power (VA/W), Frequency (50Hz/60Hz), Construction type (Toroidal/EI/R), Installation method, and Insulation Grade.

Q:Which should I choose: Toroidal or EI transformer?

Toroidal offers high efficiency and low interference but is larger and costlier. EI is smaller, lighter, cheaper, and easier to maintain, suitable for general industrial use.

Q:Is there a shielding layer in transformers?

Yes, a copper foil shielding layer can be added between primary and secondary coils to suppress high-frequency interference and enhance EMI resistance.

Q:How do you ensure quality and service life?

We use high-grade silicon steel and pure copper, apply VPI process, and conduct 100% factory tests including Hi-Pot, inter-winding, and load tests.

Q:What is the price and minimum order quantity (MOQ)?

Price depends on power and complexity. MOQ is lower for standard specs (e.g., 100pcs) and higher for custom specs (e.g., 500-1000pcs) due to mold costs.
