About Wuhan Unique Mechanical and Electrical Equipment Co.,Ltd. - Electric Components Supplier in China

Based in Wuhan, China, Wuhan Unique Mechanical and Electrical Equipment Co.,Ltd. lists eleven active products across the electric components, electric testers, and tools & instruments categories. The catalogue focuses on rectifier modules used in telecom and industrial power applications, with model numbers such as 241122.125, EATON APR48-3G and HUAWEI R4850G2. Most entries carry the HS code 8504.40, which classifies them as static converters or rectifiers under Chapter 85 of the Harmonized System. Materials referenced include steel housings, copper busbars, aluminum heat sinks and printed circuit board assemblies. The supplier’s product set therefore spans a narrow technical niche within power conversion equipment.

Product Range and Specialties of Wuhan Unique Mechanical and Electrical Equipment Co.,Ltd.

The current catalogue consists of eleven rectifier modules, all designed for 48 V DC input and power ratings between 1.8 kW and 2.9 kW. Model identifiers include Eltek Flatpack S series (e.g., 241122.125, 241122.205), Eaton NPR48‑ES, and Emerson R48‑2900U, each built with steel or metal enclosures, copper busbars and PCB‑mounted semiconductor devices. The entries that include an HS code use 8504.40, the standard classification for static converters and rectifiers.

In the wider market, 48 V rectifier modules are commonly graded by output power, efficiency and thermal design. Buyers typically look for compliance with IEC 61800‑3, IEC 60950‑1 (or IEC 62368‑1 for newer designs) and RoHS restriction of hazardous substances. Certifications such as CE, UL and IECEx are frequently required for telecom and safety‑critical installations. Standard packaging involves anti‑static pallets or wooden crates, with each 20 ft container capable of holding roughly 200 - 250 modules depending on dimensions.

Trade and Export Information - Wuhan Unique Mechanical and Electrical Equipment Co.,Ltd.

Rectifier modules classified under HS code 8504.40 are exported from China to regions including Southeast Asia, Europe, the Middle East and North America, where they are integrated into telecom base stations, data‑center UPS units and small renewable‑energy inverters. Chinese exporters usually ship these items on FOB or CIF terms, using 20‑ft or 40‑ft containers with internal bracing to protect the steel‑cased units. Importing countries often require pre‑shipment inspection under the China Inspection and Quarantine (CIQ) system and conformity documentation such as CE or UL test reports.

Typical buyers request product specifications, test certificates and compliance statements before release of payment. The static converter category may be subject to additional regulations like the EU Low Voltage Directive and the US FCC Part 15 for electromagnetic compatibility. Suppliers from China often provide factory‑level quality control reports and can arrange third‑party inspection agencies to verify performance against IEC standards.

Sourcing from Wuhan Unique Mechanical and Electrical Equipment Co.,Ltd. - Buyer Guidance

When sourcing rectifier modules from Wuhan Unique Mechanical and Electrical Equipment Co.,Ltd., buyers should obtain the detailed data sheet for each model, confirming input voltage, output power, efficiency, operating temperature range and dimensions. Request RoHS compliance statements and, if required for the target market, CE, UL or IECEx certification test reports. Because the catalogue does not list MOQ, it is prudent to ask for the minimum order quantity and lead time, which for similar Chinese manufacturers ranges from 100 units and 4‑6 weeks production.

Samples of a single unit can be requested to evaluate thermal performance and mechanical fit before committing to larger volumes. Verify that the steel housing conforms to IP‑rated protection (commonly IP 20 or IP 54 for telecom equipment) and that the copper busbars meet the specified current rating. Confirm that the supplied HS code 8504.40 matches the customs declaration to avoid clearance delays.

What types of rectifier modules does Wuhan Unique Mechanical and Electrical Equipment Co.,Ltd. list in its catalogue?

The catalogue lists eleven rectifier modules, including Eltek Flatpack S series (e.g., 241122.125, 241122.205), Eaton APR48‑3G and NPR48‑ES, Emerson R48‑2900U, and a Huawei R4850G2 model. All are designed for 48 V DC input and power outputs from 1.8 kW to 2.9 kW.

Which HS code is associated with the rectifier modules offered by the supplier?

For the products that specify a code, the HS code is 8504.40, which covers static converters and rectifiers under Chapter 85. The few entries without an HS code should be verified with the supplier before customs filing.

What are the typical voltage and power specifications for the listed rectifiers?

All models operate at a nominal 48 V DC input. Power ratings range from 1,800 W (e.g., Eltek Flatpack S 48V 1800W) to 2,900 W (e.g., Emerson R48‑2900U). Efficiency values are not listed but comparable units usually achieve 95 % - 98 % conversion efficiency.

What material construction is common among the supplier’s rectifier models?

The modules are built with steel or metal housings, copper busbars, aluminum heat sinks and printed circuit board assemblies that contain power semiconductors and magnetic cores. This combination provides mechanical robustness and effective thermal dissipation.

Which certifications should a buyer request for these rectifier modules?

Buyers should request RoHS compliance statements and, depending on the target market, CE, UL or IECEx test reports. These certifications are standard for telecom and safety‑critical power equipment.

What packaging and shipping methods are normally used for 48 V rectifier modules exported from China?

Exporters typically pack the steel‑cased units on anti‑static pallets or in wooden crates, often within a 20‑ft or 40‑ft container. Shipping terms are commonly FOB or CIF, with internal bracing to prevent movement during transit.

What documentation is recommended to verify compliance before placing an order?

Request the full product data sheet, test reports (efficiency, thermal performance), RoHS declaration, and any applicable CE, UL or IECEx certificates. Additionally, obtain the HS code declaration (8504.40) and confirm the manufacturer’s quality‑control procedures through a third‑party inspection report.
