The Agilent-Hp 6284A Power Supply has separate coarse and fine voltage and current controls that allow the voltage and current outputs to be varied from zero to the maximum rated values very easily and accurately. Crossover from constant voltage to constant current operation occurs automatically when the load current exceeds the value established by the current control settings. DC output voltage is 0 to 20 V; output current is 0 to 3 A. Easy-to read meter and simple front-panel controls.
