What is the price and MOQ?

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

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 you provide samples?

Yes, samples are available for serious customers. A fee is usually required but can be refunded after bulk order. Lead time is 3-5 days.

What are common reasons for transformer failure and is there a warranty?

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

AI-Powered supplier vetting

SummaryHANGZHOU UDWELLS TECHNOLOGY CO. Ltd. is a combined company with a strong technological base and significant production capacity. It offers OEM services for popular brands and operates more than 10 production lines. However, there are gaps in R&D documentation and service capability procedures. The company does not hold SDKs for development, nor does it have overseas facilities or participate in trade shows. Its primary export market is Europe, and it has proximity to major ports in China.

Supplier typeThe supplier is identified as a 'Combined' type company, indicating a diverse business scope.

After-Sales capabilityThe supplier provides technical support for production and after-sales service but lacks documented procedures for service capability and customer complaint handling.

R&D capabilityThe company lacks R&D audit documentation and SDK availability, indicating limitations in software development and innovation processes.

Production capacityThe supplier operates 27 production lines, indicating robust manufacturing capacity. Its annual production output ranges from US$1 Million to US$2.5 Million.

Customization capabilityThe supplier provides OEM services for well-known brands, demonstrating its ability to customize production.

Product Q&A

Q:What specifications are needed for a 220V to 12V step down transformer?

Please provide Input Voltage, Output Voltage & Current, Rated Power (VA/W), Frequency (50Hz/60Hz), Construction type, Installation method, and Insulation Grade.

Q:What is the difference between VA and W?

VA equals W for resistive loads. For inductive loads like motors, W is less than VA. Select based on apparent power (VA) with a 20%-30% margin.

Q:Should I choose a 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 the transformer?

Yes, a copper foil shielding layer can be added between primary and secondary coils to suppress high 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.
