SM800 - Laboratory Power Supply

Product Overview

Delta Elektronika SM800 Laboratory Power Supply

Delta Elektronika's 800 W laboratory, bench power supplies, some with two output autoadjusted ranges. The outputs are very stable and accurate and settings can be made either manually of by digital control. The potentiometers can be digital decoders. Very low noise, electrically but also audible. Many features including build-in data interfaces Ethernet, RS232, GPIB, IEEE488. Replaces SM7020D and SM3004D.
