About Lisun Electronics (shanghai) Co., Ltd. - Electronic Testers Supplier in China

Lisun Electronics (shanghai) Co., Ltd. is based in Shanghai, China and currently lists five active products. The catalogue is grouped under electronic meters, satellite receivers/transmitters and electronic testers, with a focus on electromagnetic compatibility (EMC) and electro‑static discharge (ESD) measurement equipment. The listed items fall under HS chapter 90, specifically HS codes 9030.40 for the KH3961 EMI Test System and 9030.89 for the EFT61000‑4 EFT Immunity Measurement unit. Materials noted include electronic components, steel housing and precision hardware assemblies, reflecting typical construction for laboratory‑grade test gear.

The product set includes an ESD61000‑2 electrostatic discharge simulator, a KH3961 EMI test system, a KH3962 EMI receiver system, an EFT61000‑4 EFT immunity measurement unit, and a SUG255 impulse withstand voltage tester. These instruments are designed for compliance testing of electronic devices against IEC 61000 series standards. The catalogue does not specify additional HS codes for the ESD simulator, impulse tester or the EMI receiver, but they belong to the same HS 9030 family used for testing apparatus.

Product Range and Specialties of Lisun Electronics (shanghai) Co., Ltd.

Lisun’s current catalogue covers five distinct test instruments. The ESD61000‑2 simulator is used for IEC 61000‑4‑2 ESD testing, typically delivering discharge pulses up to 30 kV with a rise time of 1 - 2 ns. The KH3961 EMI Test System and KH3962 EMI Receiver System are standard EMC test rigs that operate across 30 MHz to 6 GHz and support IEC 61000‑4‑3 radiated immunity and IEC 61000‑4‑6 conducted immunity tests. The EFT61000‑4 unit measures susceptibility to fast transient bursts as defined in IEC 61000‑4‑4, often configured for 150 V peak amplitude bursts of 1 - 5 µs. The SUG255 impulse withstand voltage tester provides impulse voltages up to 5 kV for surge testing in line with IEC 61000‑4‑5. In the broader industry, such equipment is commonly supplied with IEC‑type safety markings, CE or FCC declarations, and calibrated to ISO 17025 standards.

Typical grades for these devices include Class A/B performance for EMI receivers, and IEC‑specified dynamic resistance for ESD generators. Buyers frequently look for modular test heads, interchangeable antennas, and built‑in data logging capability, all of which are standard features in comparable test equipment from other manufacturers.

Trade and Export Information - Lisun Electronics (shanghai) Co., Ltd.

China is a leading exporter of EMC and ESD test instruments, with Shanghai serving as a major logistics hub for containerised shipments. HS 9030.40 and HS 9030.89 are routinely inspected under China’s export control regime and may require a test report confirming conformity to IEC 61000 standards. Major import markets include the United States, the European Union, and Southeast Asian manufacturing hubs, where buyers often request CE, FCC, or UL certifications alongside a Declaration of Conformity. Packaging for these precision devices typically involves anti‑static foam inserts, double‑wall cardboard, and wooden pallets for 20‑ft or 40‑ft containers, with FOB Shanghai or CIF destination as common Incoterms. Export documentation generally includes a commercial invoice, packing list, certificate of origin, and, where required, a test report or calibration certificate.

Regulatory bodies such as the EU’s RoHS directive and the US FCC Part 15 may affect the import of test equipment, so buyers should verify that the supplied units meet relevant electromagnetic emission limits and hazardous substance restrictions before clearance.

Sourcing from Lisun Electronics (shanghai) Co., Ltd. - Buyer Guidance

When sourcing from Lisun Electronics, buyers should request the latest IEC‑compliance test reports for each instrument, as well as calibration certificates traceable to an ISO 17025 accredited laboratory. Samples of user manuals and wiring diagrams are useful to confirm that the software interface supports the required test scripts and data export formats (CSV, XML). Because the catalogue does not list any certifications, buyers are advised to ask for CE, FCC or UL declarations and to verify that the steel housing complies with RoHS limits on restricted substances. Verify the model numbers, HS codes and material descriptions against the purchase order to avoid mismatches, especially for the KH3961 (HS 9030.40) and EFT61000‑4 (HS 9030.89) units.

Typical minimum order quantities for laboratory test equipment range from one unit to a small batch of five, with lead times of 30‑45 days for calibrated units and up to 60 days for custom‑configured systems. Payment terms often follow a TT advance or LC at sight, aligned with the chosen Incoterm.

What product categories does Lisun Electronics list?

Lisun Electronics lists five products under electronic meters, satellite receivers/transmitters and electronic testers, specifically ESD simulators, EMI test and receiver systems, EFT immunity measurement units and impulse voltage testers.

Which HS codes are associated with Lisun’s catalogue?

The KH3961 EMI Test System is classified under HS 9030.40 and the EFT61000‑4 EFT Immunity Measurement unit under HS 9030.89. The other three products are not assigned HS codes in the provided data but fall within the HS 9030 family for testing apparatus.

What standards are typically required for the ESD61000‑2 simulator?

Buyers normally require IEC 61000‑4‑2 compliance, which defines discharge voltage up to 30 kV, rise time of 1 - 2 ns, and repeatability within ±5 %. Certification such as CE or FCC is also commonly requested.

Are calibration certificates needed for the KH3961 EMI Test System?

Yes, an ISO 17025 calibration certificate is standard for EMI test equipment and should be requested to confirm frequency accuracy, dynamic range and antenna performance.

What is the usual packaging for these test instruments?

The instruments are typically packed in anti‑static foam inserts inside double‑wall cardboard boxes, then palletised on wooden pallets for sea freight. Containers of 20 ft or 40 ft are used depending on order size.

Which markets commonly import Chinese EMC test equipment?

The United States, the European Union and Southeast Asian manufacturing regions are the primary import markets for Chinese EMC and ESD test devices.

What documentation should a buyer ask for before placing an order?

Request a commercial invoice, packing list, certificate of origin, IEC compliance test report, calibration certificate, and any CE/FCC/UL declarations relevant to the product.

What are typical lead times for these products?

Lead times range from 30 days for standard calibrated units to up to 60 days for units that require custom configuration or additional certification.
