Product Descriptions :
- KPS3030DA/KPS3050DA is DC switching power supply with constant voltage and constant current operation method. KPS series have some advantages such as large output current (KPS3030DA output current with 30A, KPS3050DA output current with 50A), light weight, over temperature protection inserted in the machine and so on. KPS series can be used as laboratory research and develop system power supply, it also can be used as production and maintenance aging test power supply. they are the necessary device for technology and research, production, teaching institution
- Power supply appears overheating operation status, output will be closed.
- When machine internal temperature recovery normal, power supply output recoveries default condition
