Keithley programmable supply has 0.03% accuracy
Wednesday 28 September 2011
Keithley Instruments has introduced five general-purpose programmable DC power supplies with models ranging from 20V/100A to 72V/1.2A.
The voltage output accuracy of Series 2200 power supplies is specified at 0.03%; their current output accuracy is 0.05%.
Output resolution is 1mV and measurement resolution is 0.1mA.
Remote sense terminals on the back panel and less than 5mVp-p noise help ensure that the voltage programmed is the voltage that the supply actually outputs.
A dual-line display shows both the programmed values and actual outputs for a continuous indication of the status of the power delivered to the load.
Features include 40 memory locations for storing frequently used test setups for later recall and reuse.
There is also a built-in list mode function supports the programming and storage of up to seven custom test sequences of up to 80 steps. Once saved, a sequence can be triggered to run manually using the instrument’s front panel keys, automatically via an external trigger, or by using programmable interface commands.
Series 2200 power supplies can be controlled easily over either a standard GPIB or USB interface.
