Keithley Launches New General Purpose Programmable Power Supply Product Line
Keithley
Instruments, Inc., a world leader in advanced electrical test
instruments and systems, announced today the availability of five new
general-purpose programmable DC power supplies designed to complement
the company’s existing line of specialty power
supplies and source
measurement instruments for component, module, and device
characterization and test applications. The Series 2200 family combines
superior voltage and current output accuracy at a cost-effective price,
flexible operation, and features designed to enhance ease of use in a
variety of device characterization or test applications. More
information on the Series 2200 is available on Keithley’s website: http://www.keithley.com/data?asset=55901
The five models in the Series 2200 line offer maximum voltage, current,
and power output levels designed to address a wide range of sourcing
requirements for characterizing components, circuits, modules, and
complete devices:
Model 2200-20-5: 20V, 5A, 100W
Model 2200-30-5: 30V, 5A, 150W
Model 2200-32-3: 32V, 3A, 96W
Model 2200-60-2: 60V, 2.5A, 150W
Model 2200-72-1: 72V, 1.2A, 86W
High output accuracy
The voltage output accuracy of Series 2200 power supplies is specified
at 0.03%; their current output accuracy is 0.05%. Both specifications
are significantly better than those of competitive general-purpose
supplies. In addition, their high output (1mV) and measurement (0.1mA)
resolution makes them 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 today’s 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.
Flexible operation
Series 2200 supplies include a variety of features designed to enhance
operating versatility. For example, each model provides 40 onboard
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 instrument’s front panel keys, automatically via an external
trigger, or by using programmable interface commands. Competitive
general-purpose power supplies don’t provide these capabilities.
Protection for the devices under test (DUTs)
Several Series 2200 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. These limits are in addition to the
current limit setting function, which controls the level of current that
can flow into the DUT. Also, a programmable timer can be used to turn
off the output after a specified time interval, so tests can be
preprogrammed to run unattended without worrying about excess voltage or
power being applied to the DUT for an extended period of time.
Superior ease of use
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.
Pricing and Availability
The U.S. list price of the Series 2200 instruments are as follows, with
shipments beginning in December 2011.
Model 2200-20-5: $925
Model 2200-30-5: $1090
Model 2200-32-3: $925
Model 2200-60-2: $1090
Model 2200-72-1: $925
