About Wattsine Electronic Technology Co., Ltd. - Electric Power Generators Supplier in China

Based in China, Wattsine Electronic Technology Co., Ltd. lists seven active products in its catalogue. The portfolio concentrates on high‑frequency power equipment such as RF amplifiers and microwave generators, which fall under the broader categories of Electric Power Generators, Amplifiers, Light Emitting Diode and Electric Sensors. The sole product with a disclosed HS code is the “RF amplifier 2450mhz 5kw” classified under HS 8543.70, a heading for other electrical machines and apparatus. The remaining six items are various solid‑state microwave generators operating at 915 MHz, 2.45 GHz and 433 MHz with power ratings from 200 W to 6 kW.

All listed devices incorporate metallic housings combined with copper or brass RF components and semiconductor modules, typical for high‑power RF equipment. The frequency bands (433 MHz, 915 MHz, 2.45 GHz) correspond to ISM and licensed industrial bands frequently used in telecommunications, radar and heating applications. The power levels span 200 W, 500 W, 1 kW, 2 kW, 3 kW and 6 kW, providing a range that matches both laboratory test rigs and small‑scale production lines. No additional HS codes are provided for the other generators, but they are generally grouped under HS 8543.90 (other electrical machines).

Product Range and Specialties of Wattsine Electronic Technology Co., Ltd.

Wattsine’s catalogue includes a 5 kW RF amplifier (HS 8543.70) and six solid‑state microwave generators covering 433 MHz to 2.45 GHz with output powers from 200 W up to 6 kW. In the RF amplifier market, typical specifications include gain of 30 - 40 dB, efficiency above 70 %, and a harmonic distortion below - 40 dBc, while microwave generators are commonly evaluated on frequency stability (±0.1 %), power output tolerance (±5 %), and cooling method (forced air or liquid).

Industry standards for such equipment often reference IEC 60950‑1 for safety, IEC 61000‑4‑3 for electromagnetic compatibility, and FCC Part 15 for emissions in the United States. Buyers usually look for CE marking in Europe and RoHS compliance to limit hazardous substances. Typical material grades involve aluminum or steel enclosures with copper windings and silicon‑based semiconductor devices, delivering thermal resistance values around 0.5 °C/W for the power transistors.

Trade and Export Information - Wattsine Electronic Technology Co., Ltd.

China is a major exporter of RF and microwave power devices, with shipments commonly destined for North America, the European Union, and Southeast Asian markets. The HS 8543 family is monitored by customs authorities for compliance with safety and electromagnetic compatibility regulations, and many importers require pre‑shipment inspection certificates such as CE Declaration of Conformity or FCC test reports. Standard Incoterms used by Chinese manufacturers include FOB Shanghai and CIF Hong Kong, with container loads typically fitting 20‑ft or 40‑ft units depending on packaging.

Export logistics for 200 W to 6 kW generators usually involve anti‑static wooden crates or metal pallets, with each unit weighing between 8 kg and 25 kg. Volume calculations often allow 12 - 15 solid‑state generators per 20‑ft container when packed in protective foam inserts. Buyers should verify that the shipment complies with the destination country’s radio‑frequency spectrum allocation to avoid licensing issues.

Sourcing from Wattsine Electronic Technology Co., Ltd. - Buyer Guidance

When sourcing from Wattsine, request a full technical datasheet that lists frequency tolerance, output power, efficiency, cooling requirements and safety certifications such as CE or FCC. Independent test reports covering harmonic distortion, VSWR and thermal performance help confirm that the unit meets industry tolerances. Samples of the enclosure material and a photomicrograph of the semiconductor modules can be useful for quality verification before a larger order.

Typical minimum order quantities for solid‑state microwave generators range from a single unit for prototype testing to 10 units for production runs, with lead times of 4 - 6 weeks after order confirmation and receipt of required certifications. Buyers should arrange for packaging confirmation (anti‑static wrapping, moisture‑proof pallets) and consider insurance under CIF terms to cover transit risks.

What frequency bands are covered by Wattsine’s microwave generators?

The catalogue lists generators at 433 MHz, 915 MHz, and 2.45 GHz, which correspond to common ISM and licensed industrial bands used for communications, radar and heating applications.

Which HS code applies to the RF amplifier in the catalogue?

The “RF amplifier 2450mhz 5kw” is classified under HS 8543.70, the heading for other electrical machines and apparatus.

What certifications should a buyer request for these RF power products?

Buyers typically request CE marking for the European market, FCC test reports for the United States, and RoHS compliance certificates to confirm restriction of hazardous substances.

What are the typical power ratings and output specifications for the listed generators?

Power ratings range from 200 W to 6 kW; standard specifications include frequency stability within ±0.1 %, output power tolerance of ±5 % and efficiency values above 70 % for solid‑state designs.

How are the generators usually packaged for international shipment?

They are packed in anti‑static wooden crates or metal pallets with foam inserts, each unit weighing between 8 kg and 25 kg, allowing 12 - 15 units per 20‑ft container.

What is a common lead time and MOQ for these items?

Lead times are typically 4 - 6 weeks after order confirmation, and minimum order quantities can start at one unit for prototype testing, scaling up to 10 units for regular production.

Which regulatory tests are relevant for RF amplifiers and microwave generators?

Relevant tests include electromagnetic compatibility (EMC) per IEC 61000‑4‑3, safety testing per IEC 60950‑1, and harmonic distortion measurements (often required to be below - 40 dBc).

What documentation is needed to clear customs for HS 8543 items?

A commercial invoice, packing list, certificate of origin, and any applicable conformity certificates (CE, FCC) are normally required for customs clearance of HS 8543 goods.
