Keithley
Instruments, Inc., a world leader in advanced electrical
test instruments and systems, announced 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.
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.
