Quality Assurance
DQA Verification: Reliable Power from Design to Delivery
We strictly follow the principle of separation of design and verification. At the beginning of new product development, the DQA verification center affiliated with the quality department conducts independent product verification to ensure the R&D design quality of the power supply from the design source. Quankang has an independent system, which can realize EVT, DVT, and PVT testing at different stages of product development.
