Note: DC power supply is a high-power DC output power supply, which is a high-voltage equipment. The program control system is customized for photovoltaic power station scenarios, which can better ensure the safety of on-site manual construction. However, high-voltage equipment is still a high-risk equipment. Please strictly follow the operating instructions and standardize wiring and operation. In the event of power protection, contact the manufacturer as soon as possible to solve the problem. Do not operate the wiring without authorization to prevent danger! ! !
