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 production?
A:
Please provide Input Voltage, Output Voltage & Current, Rated Power, Frequency, Construction type, Installation method, and Insulation Grade.
Q:What is the difference between VA and W?
A:
VA equals W for resistive loads. For inductive loads, W is less than VA. Select based on apparent power (VA) with a 20-30% margin.
Q:Which should I choose, Toroidal or EI transformer?
A:
Toroidal offers higher efficiency and lower interference but is larger and costlier. EI is smaller, lighter, and more cost-effective for general use.
Q:Is there a shielding layer in transformers?
A:
Yes, a copper foil shielding layer can be added between coils to suppress high interference and enhance EMI resistance.
Q:How do you ensure quality and service life?
A:
We use high-grade materials, vacuum impregnation process, and conduct 100% factory testing including Hi-Pot and load tests.
