About Beijing V-Young Tech.Development Co., Ltd. - Electric Transformers Supplier in China

Beijing, China hosts Beijing V-Young Tech.Development Co., Ltd., which currently lists five active products. The catalogue covers items in the Electric Transformers and Converters & Switches categories, including a DC‑DC converter, DC‑DC power supplies, a Toroidal transformer (Chock Coi), a PCB‑mounted AC‑DC converter module, and a high‑frequency transformer/inductor/coil. Each product falls under the HS chapter 85 group for electrical machinery, with sub‑headings commonly used for power conversion equipment. The supplier’s listing reflects a focus on compact power conversion and magnetic component solutions for industrial and electronic applications.

The five products span both low‑voltage DC conversion and high‑frequency magnetic devices, indicating capabilities ranging from 5 V to 400 V DC outputs and operating frequencies up to several megahertz. Typical specifications for such items include efficiency levels above 85 %, ripple voltage under 5 % of output, and insulation class B or F for transformers. The catalogue does not specify certifications, so buyers should verify compliance with IEC standards such as IEC 61800‑1 for converters and IEC 60076 for transformers. The product mix suggests suitability for OEMs, system integrators, and equipment manufacturers requiring reliable power conversion blocks.

Product Range and Specialties of Beijing V-Young Tech.Development Co., Ltd.

The catalogue’s DC‑DC converter and DC‑DC power supplies are standard isolated or non‑isolated modules used in telecom, automotive, and industrial control. In the market, buyers usually request output voltage tolerance of ±2 % and efficiency class up to IEC 60950‑1 compliance. Toroidal transformers (listed as Chock Coi) are typically rated in the 10 W to 500 W range, with core losses measured in milliwatts and a common IEC 60076‑2 grade. PCB‑mounted AC‑DC converter modules combine compact size with input ranges of 85‑264 VAC and output regulation within ±3 %.

High‑frequency transformers, inductors, and coils are employed in switch‑mode power supplies and RF applications, where inductance values from 10 µH to several millihenries and self‑resonant frequencies above 10 MHz are common. Industry standards often cite IEC 60384‑14 for inductors and IEC 61800‑3 for high‑frequency converters. Buyers typically look for copper winding resistance below 0.1 Ω, temperature rise under load not exceeding 30 °C, and compliance with RoHS restrictions on hazardous substances.

Trade and Export Information - Beijing V-Young Tech.Development Co., Ltd.

China is a major exporter of power conversion and magnetic components, with the majority of shipments directed to Europe, North America, and the Asia‑Pacific region. HS chapter 85 codes covering transformers (8504.30), converters (8504.40) and inductors (8504.50) are routinely inspected under the ASEAN‑China Free Trade Area and EU customs procedures. Common buyer requirements include CE marking for the EU market, UL certification for North America, and IEC test reports for efficiency, temperature rise, and dielectric strength.

Export logistics for these items typically involve 20‑ft or 40‑ft containers with anti‑static or ESD‑protected packaging, and Incoterms such as FOB Shanghai or CIF Los Angeles are frequently used. Suppliers from China often provide product data sheets, third‑party test certificates, and material safety data sheets (MSDS) to satisfy import regulations. Buyers should confirm that the supplier can meet packaging standards like ISPM 15 for wooden pallets if used.

Sourcing from Beijing V-Young Tech.Development Co., Ltd. - Buyer Guidance

When sourcing DC‑DC converters or power supplies, request a detailed datasheet specifying input/output voltage ranges, efficiency curves, ripple voltage, isolation voltage, and operating temperature. Verify that the unit complies with IEC 61800‑3 and, where applicable, has undergone UL 60950‑1 or IEC 60950‑1 testing. For transformers and inductors, ask for core material data (e.g., silicon steel or ferrite), inductance tolerance, loss measurements, and a certificate of compliance with IEC 60076‑2.

Samples should be shipped in anti‑static packaging and accompanied by a test report from an accredited laboratory. Confirm the minimum order quantity - often 100 units for modules and 500 units for bulk inductors - and typical lead times of 4‑6 weeks after order confirmation. Ensure that the supplier can provide RoHS compliance statements and, if needed, a CE Declaration of Conformity before shipment.

What product categories does Beijing V-Young Tech.Development Co., Ltd. offer?

The supplier lists items under Electric Transformers and Converters & Switches, specifically a DC‑DC converter, DC‑DC power supplies, a Toroidal transformer, a PCB‑mounted AC‑DC converter module, and a high‑frequency transformer/inductor/coil.

How can I obtain technical specifications for the DC‑DC converters?

Request the supplier’s datasheet, which should detail input voltage range, output voltage, efficiency, ripple, isolation voltage, operating temperature and compliance with IEC 61800‑3.

Which certifications should I request for the transformers?

Typical certifications include IEC 60076 test reports, CE marking for EU shipment, and, where required, UL certification for North American markets. RoHS compliance statements are also standard.

What are typical minimum order quantities for the PCB‑mounted modules?

Buyers in this segment usually face a minimum order of around 100 units per SKU, though exact figures depend on the specific module size and customization.

What lead time is common for high‑frequency inductors?

Lead times of 4‑6 weeks are common after order confirmation, assuming standard specifications and no custom winding requirements.

How are the products packaged for international shipment?

Items are typically packed in anti‑static or ESD‑protected cardboard, placed on pallets with stretch wrap, and comply with ISPM 15 when wooden packaging is used.

Which HS codes are applicable to the items in this catalogue?

The products fall under HS chapter 85, with sub‑headings such as 8504.30 for transformers, 8504.40 for converters, and 8504.50 for inductors, which are the standard classifications used by customs for these types of electrical equipment.
