Ainuo Instrument Co.Ltd

What Ainuo Instrument Co.Ltd does

Ainuo Instrument Co., Ltd. is a privately held Chinese manufacturer of power electronics test and measurement instruments, founded in 1993 and headquartered in Qingdao, Shandong Province, with a second self-built industrial park in Jinan. The company organizes its offering into three core segments: source and load instruments (AC power sources from 500W to 2000kW, programmable and bidirectional DC power supplies from 1kW to 1000kW, electronic loads including regenerative variants, and four-quadrant power supplies); testing instruments (electrical safety analyzers for hipot, ACW, DCW, insulation resistance, ground bond, and leakage current testing per IEC 60601-1 and equivalent standards, plus motor stator/complete-machine testers and partial discharge testers); and measurement instruments (multi-channel and three-phase power analyzers with accuracy down to 0.03% of reading and bandwidth to 1MHz). Product differentiators include energy regeneration that returns absorbed power to the grid (typically >90% efficiency), high-speed dynamic loading up to 50kHz with current rise rates of 96A/μs, FLEX mode impedance simulation, photovoltaic I-V curve simulation, and four-quadrant operation.

The company serves industrial B2B customers across at least seven verticals: new energy vehicles (battery, OBC, DCDC, charging pile, EV electronics testing), photovoltaic and energy storage (inverter, PV module, storage converter testing), lithium battery and fuel cell testing, AIDC/data center power supply testing, household appliance and motor manufacturing, aerospace (400Hz ground power, intermediate frequency solid-state supplies, wideband static supplies), and quality inspection/metrology institutions. Revenue is generated through direct hardware sales via a quote-based pricing model, with go-to-market executed through a company website inquiry system, multilingual websites (Chinese, English, Russian, German), and active participation in international trade shows including FEIMEC and FIEE in Brazil, VIAF/VIMF and NEPCON in Vietnam, Thailand Sustainable Energy Week, and APEC in the USA. The company holds over 300 intellectual property rights including over 100 invention patents and has hosted or contributed to national and industrial standards development in electrical safety testing and power electronics measurement.

The business is founder-owned with no disclosed institutional investors, parent entity, subsidiaries, or M&A activity. After-sales service operates domestically in China through a dedicated service email and 24/7 telephone support. Pricing is not publicly disclosed and is handled via direct inquiry, with multi-year contract structures typical of industrial B2B equipment sales. No AI/ML capabilities, mobile applications, third-party integrations, or public APIs are disclosed in the available materials.
