DC Power Supplies, Battery Chargers & Battery Simulators

Keithley & Tektronix power supplies offer a wide range of performance.
Get single channel models with superior accuracy and 0.1mA current
measurement resolution. New high voltage power supplies combine high
voltage with sensitive, low current measurement for high voltage device
testing and characterization and high voltage research. For multiple
source needs, select a dual channel or triple channel supply. All channels
are isolated and fully programmable. For testing battery-operated
devices, consider a battery simulator.
