In the field of power supply burn-in testing, the choices of top-tier enterprises represent the ultimate endorsement of technical strength and product value. With over a decade of deep cultivation, core technologies, full-scenario customized solutions, and extremely reliable product quality, Shenzhen Kesi Electronics Co., Ltd. has developed power burn-in equipment featuring energy efficiency, precision and stability. It has successfully won recognition from industry giants such as CASIC and Bull Group, becoming a core partner for quality control among leading enterprises, and setting an industry benchmark with robust capabilities.
Building Barriers Through Technological Innovation, Breaking Into the High-End Market
Leading enterprises impose strict technical requirements on burn-in equipment. Kesi Electronics has built core competitiveness through full-stack R&D capabilities. Core members of the R&D team each have more than 10 years of industry experience, leading the development of over 50 industry invention patents and software copyrights in total, forming a complete technical system from hardware design to software development.
Among them, the newly patented Power Supply Burn-In Test Device with Under-Voltage Protection Module precisely solves the industry pain point of front-end equipment damage caused by grid-connected inverter faults, providing dual safety protection for high-power power supply testing. Its technological foresight has earned recognition from military-grade enterprises including CASIC.

Meanwhile, keeping pace with the “Dual Carbon” strategy, Kesi integrates high-efficiency energy feedback technology with an energy feedback efficiency of over 92%, helping customers reduce power consumption by approximately 80%. In large-scale testing scenarios for mass producers such as Bull Group, it achieves simultaneous reduction in testing costs and carbon emissions, aligning with the core needs of leading enterprises for cost reduction, efficiency improvement and green production.
Full Coverage of Customized Solutions, Precisely Matching Diverse Needs
Testing scenarios vary greatly among top enterprises in different industries, making standardized equipment unsuitable for personalized demands. Kesi Electronics delivers full-scenario customized solutions centered on customer needs, supporting all product categories from consumer-grade to aerospace-grade power supplies.
For leading consumer electronics enterprises such as Bull Group, we provide customized multi-channel parallel burn-in solutions supporting synchronous testing of 8–32 channels, equipped with automatic fast-charging protocol identification modules. These adapt to mass production testing of chargers and adapters, balancing efficiency and precision while helping reduce after-sales failure rates.
For special power supply requirements of CASIC, we deliver extreme-environment burn-in systems supporting vacuum, low-temperature, high-impact and 400Hz special frequency testing, with full-process data traceability and encrypted storage, fully meeting military-grade quality control standards.
For leading new energy vehicle manufacturers and energy storage enterprises, we offer wide-temperature-range high-voltage burn-in solutions covering −40°C to 85°C, integrated with 10kV high-voltage insulation protection and dynamic load switching. These accurately reproduce extreme working conditions of automotive and energy storage power supplies, satisfying stringent certification requirements for automotive and energy storage projects.
Upholding Reliability as the Bottom Line, Winning Long-Term Trust Through Quality
Leading enterprises demand far higher equipment stability than the industry average. Kesi Electronics implements strict control from component selection to production management. All core components are sourced from internationally renowned brands, and the equipment’s Mean Time Between Failures (MTBF) exceeds 2,000,000 hours, supporting stable 7×24-hour uninterrupted operation to fully meet large-scale, long-cycle testing requirements.
In Bull Group’s mass production workshops, Kesi burn-in equipment has long been responsible for high-volume charger testing. With precise temperature rise control and ripple detection, it detects early failures such as loose connectors and capacitor bulging in advance, helping reduce after-sales failure rates by 30%–60%.
In CASIC laboratories, Kesi equipment has withstood rigorous extreme environment simulations, maintaining accurate parameter collection and stable operation, providing solid support for reliability verification of aerospace-grade power supplies. Such “zero-fault, high-precision” stable performance is the core reason why leading enterprises continue to choose Kesi.
Full-Cycle Service Support, Building an In-Depth Cooperation Ecosystem
Large-scale production and R&D iteration of leading enterprises rely on comprehensive service support. Kesi Electronics provides full life-cycle services from solution design to after-sales maintenance, with a 7×24-hour rapid response mechanism to ensure uninterrupted operation during critical testing stages.
For installation and commissioning of large-scale equipment, we provide one-on-one dedicated support, including equipment calibration, operation training and MES system integration, enabling automatic upload and traceability of test data. We also conduct regular on-site maintenance and precision calibration, and timely provide software upgrades and module expansion to ensure equipment continuously adapts to product and technological upgrades of leading enterprises.
This integrated “product + service” cooperation model makes Kesi Electronics not only an equipment supplier, but also a long-term strategic partner for quality upgrading among leading enterprises.
From stringent verification at CASIC to large-scale mass production at Bull Group, Kesi Electronics has won over leading enterprises across industries through technological strength, customization capabilities and reliable quality.
As competition in the power supply industry intensifies, recognition from top enterprises is both an honor and a responsibility. Going forward, Kesi Electronics will continue to focus on technological innovation and scenario adaptation, continuously improve its product portfolio, and empower more leading enterprises to achieve quality upgrading with higher-performance power burn-in equipment and solutions, leading the industry’s development with proven strength.
