The Rohde & Schwarz HMC8043 is a three-channel programmable linear DC power supply engineered for laboratory, industrial, research, and educational applications. Each of the three galvanically isolated outputs delivers 0 to 32 V DC at 0 to 3 A, with a maximum power rating of 33 W per channel and 100 W total output power. The instrument combines high-resolution voltage and current control with exceptionally low ripple and noise, making it suitable for precision testing and system development.
