Since starting in 2013, Zhuai Jiuyuan has focused on new energy power conversion. We developed DC programmable power supplies for lithium batteries and energy storage and advanced various other R&D innovations. Our power supplies meet the precision, efficiency, and other requirements of contemporary test environments. The shared DC bus technology that we developed reduces energy usage and improves test precision. Our power supplies become the first option for power supply manufacturers and laboratories globally. We have developed, and continue to develop, power supplies to meet customer requirements in the changing energy market.
