Choose Cosail, Be a Powerful Player in Power Supply Burn-In Testing

In the field of power supply burn-in testing, the choices of leading enterprises have always been the ultimate endorsement of technical strength and product value.With more than ten years of deep industry experience, core technologies, full-scenario customized solutions, and extremely reliable product quality, Shenzhen Cosail Electronics Co., Ltd. has developed power supply burn-in equipment featuring energy efficiency, precision and stability.It has earned recognition from industry giants such as CASIC and Bull Group, becoming a core partner for quality control among top enterprises, and setting an industry benchmark with robust strength.

Building Barriers Through Technological Innovation, Breaking Into the High-End Market

Leading enterprises impose strict technical requirements on burn-in equipment. Cosail 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 invention patents and software copyrights, 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 won recognition from military-grade enterprises including CASIC.

Meanwhile, in line with the “Dual Carbon” strategy, Cosail integrates high-efficiency energy feedback technology with an energy feedback efficiency of over 92%, helping enterprises reduce power consumption by approximately 80%.In mass testing scenarios for large-scale manufacturers such as Bull Group, it achieves both lower testing costs and carbon emissions, meeting the core needs of leading enterprises for cost reduction, efficiency improvement and green production.

Full-Coverage Customized Solutions Precisely Matching Diverse Needs

Testing scenarios vary greatly among leading enterprises in different industries, and standardized equipment can hardly meet personalized demands.Cosail Electronics provides full-scenario customized solutions centered on customer needs, supporting all types of power supplies from consumer-grade to aerospace-grade.

• For leading consumer electronics enterprises such as Bull Group, we provide customized multi-channel parallel burn-in solutions supporting 8–32 channels of synchronous testing, equipped with an automatic fast-charging protocol identification module.These are suitable for mass production testing of chargers and adapters, balancing efficiency and precision, and helping reduce after-sales failure rates.

• For special power supply requirements of CASIC, we develop 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 automakers and energy storage companies, we offer wide-temperature high-voltage burn-in solutions covering a temperature range of −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 strict certification requirements for automotive and energy storage projects.

Upholding Extreme Reliability, Winning Long-Term Trust Through Quality

Leading enterprises demand far higher equipment stability than the industry average.Cosail Electronics implements strict control from component selection to production management.Core components are all selected from world-famous 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, Cosail burn-in equipment has long been used for high-volume charger testing.With precise temperature rise control and ripple detection, it identifies early failures such as loose connectors and capacitor bulging in advance, helping reduce after-sales failure rates by 30%–60%.

In CASIC laboratories, Cosail 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 stable “zero-fault, high-precision” performance is the core reason why leading enterprises continuously choose Cosail.

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.Cosail Electronics provides full life-cycle services from solution design to after-sales maintenance, with a 7×24-hour rapid response mechanism to ensure uninterrupted equipment operation in critical testing processes.

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 provide timely software upgrades and module expansion to ensure equipment continuously adapts to product and technological upgrades of leading enterprises.

This integrated “product + service” model makes Cosail Electronics not only an equipment supplier, but also a long-term strategic partner for quality upgrading among leading enterprises.

From strict verification at CASIC to large-scale mass production at Bull Group, Cosail Electronics has won over leading enterprises across industries through technological strength, customization capabilities and reliable quality.Amid intensifying competition in the power supply industry, recognition from top enterprises is both an honor and a responsibility.

In the future, Cosail 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 supply burn-in equipment and solutions, leading the industry’s development with proven strength.
