MORNSUN LM75-20B24
75W Enclosed AC/DC Switching Power Supply with Universal Input and 24V Output
FAE Distributor's Review
The LM75-20B24 is a workhorse product we frequently recommend to our industrial control clients. Its standout features are its robust EMC performance (meeting CISPR32/EN55032 CLASS B without external components) and its wide operating temperature range of -30℃ to +70℃. This significantly simplifies system design and enhances reliability in harsh environments. Compared to similar models, its high efficiency and low no-load power consumption make it an excellent choice for energy-conscious applications.
