What is the output waveform quality?

The system provides a pure sine wave with a Total Harmonic Distortion (THD) of less than 1.0%.

Does the system require a large power supply?

No, it does not have a large starting current problem. A small capacity power supply can fulfill tests equivalent to 30 to 60 times the power supply capacity.

What is the frequency range of the output?

The output frequency ranges from 20Hz to 300Hz, with a frequency adjustment sensitivity of 0.1Hz and instability less than 0.05%.

AI-Powered supplier vetting

SummaryThe supplier operates in power testing products and related electronic, electrical, machinery, software, and information-system activities. It reports 3D design, ODM, OEM, SDK, new-product, and broad customization capabilities, with stated annual productivity of 1,500 sets for four listed testing-equipment categories. Procedures and records exist for corrective/preventive actions and customer complaints, while the supplier explicitly reports no quality assurance in quality-control processes. It has valid manufacturing contracts with associated subcontractors, but no in-stock capacity, overseas warehouse, or overseas showroom. Overseas service offerings include installation, debugging, maintenance, repair, and training, although the stated number of countries served overseas is zero. Financial evidence is incomplete and includes zero values for the listed 2024 financial metrics, so credibility cannot be established from the provided data.

Supplier typeThe supplier is positioned in the power-testing and electrical-equipment sector, with stated activities covering electronic products, software and auxiliary equipment, machinery, instruments, communication equipment, and professional design services. Its company description specifically presents one-stop power testing products and services.

After-Sales capabilityThe supplier has documented and followed procedures for corrective/preventive actions and customer complaints, and lists installation, debugging, maintenance, repair, and training services. However, it reports no overseas warehouse or showroom and zero countries where overseas services are offered, indicating limited demonstrated overseas coverage.

R&D capabilityThe supplier reports new products during the past year, ODM service, OEM service for popular brands, 3D software design, and an available SDK. These are explicit indicators of product-development and technical integration capability.

Production capacityAnnual productivity is stated as 1,500 sets each for four categories of high-voltage and related testing equipment, supported by listed machining, drilling, milling, welding, cutting, and wire-winding facilities. Valid manufacturing contracts with each associated subcontractor are also reported, although no in-stock capacity is available.

Customization capabilityThe supplier explicitly offers customization from samples and designs, full and minor customization, flexible customization, and 3D software design services. The same broad customization range appears in both its R&D and production-related information.

Product Q&A

Q:Can you provide training for our team?

Yes, we provide free training at our factory. For on-site training, we can arrange it as well. Our team of 10 seasoned engineers has experience installing and commissioning equipment in many countries.

Q:What is your after-sale service policy?

We have a dedicated after-sale service team led by our duty manager. Engineers provide answers within 1 hour and resolve equipment failures within 24 hours.

Q:What is the warranty period for the system?

The warranty period is two years. The product can be replaced within 1 month, repaired for free for one year, and maintained for lifetime. Extended warranty is available for a small fee.

Q:What is the maximum output voltage and capacity?

The rated output voltage can reach up to 1000kV depending on the test object, and the maximum capacity is up to 20000kVA.

Q:What is the partial discharge level of the system?

The partial discharge level is controlled within 5pC at rated voltage. If the voltage reaches 600kV or above, it is less than 10pC.
