Win one of two general purpose programmable power supplies delivering up to 100W
February 01, 2012 // Julien Happich
This month Keithley Instruments is giving away two of its Model 2200 power supplies, worth 735 Euros each, for EETimes Europe's readers to win. The Model 2200-20-5: 20V, 5A, 100W on offer is one of five general-purpose programmable DC power supplies recently launched by the company, designed for source measurement instruments for component, module, and device characterization and test applications. Part of the Series 2200 family, the unitís voltage output accuracy is specified at 0.03% and its current output accuracy is 0.05%.
The supplys high output (1mV) and measurement (0.1mA) resolution makes it well-suited for characterizing low power circuits and devices in applications such as measuring idle mode and sleep mode currents to confirm devices can meet todays ever-more-challenging goals for energy efficiency. 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. Each model in the Series 2200 provides 40 on-board memory locations for storing frequently used test setups for later recall and reuse. In addition, 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 instruments front panel keys, automatically via an external trigger, or by using programmable interface commands. Competitive general-purpose power supplies dont provide these capabilities. Several features help protect DUTs from damage during testing, including a programmable voltage limit value that prevents the supply from outputting excessive voltage (even if a voltage higher than the limit is entered into the instrument) and a programmable over-voltage function that causes the output to drop to less than 1V if the over-voltage limit is reached. A programmable timer can be used to turn off the output after a specified time interval, so tests can be pre-programmed to run unattended without worrying about excess voltage or power being applied to the DUT for an extended period of time. Multiple methods for adjusting the supplies voltage and current settings are provided, including a direct-entry numeric keypad on the front panel. In addition, a rotary knob with adjustable step size simplifies studying the response of a device-under-test (DUT) to voltage or current changes.
Series 2200 power supplies can be controlled easily over either a standard GPIB or USB interface. The USB interface is test and measurement class (TMC) compliant, so users can employ the standard SCPI command syntax. Standard instrument drivers are included to simplify integrating the power supplies into an automated test environment.
