Economical Triple-Channel Programmable Power Supply from Keithley Outperforms Competitive Supplies
CLEVELAND --(Business Wire)--
Keithley
Instruments, a world leader in advanced electrical test instruments
and systems, announced today the addition of an economical
triple-channel power supply to the company's Series 2200 line of
programmable DC power supplies. The Model 2231A-30-3 195W Triple-Channel
DC Power Supply combines the advantage of greater output accuracy than
competitive power supplies, with features that enhance its ease of use
in circuit
design and university student
labs for device testing applications that require multiple power
sources. Like the rest of the Series 2200 line, the Model 2231A-30-3
complements Keithley's broad source and measurement instrumentation
offering. More information on the Model 2231A-30-3 is available on the
company's website at www.keithley.com/data?asset=58151.
The Model 2231A-30-3's output levels address a wide range of sourcing
requirements for characterizing components, circuits, modules, and
complete devices. Two of the output channels are typically used for
powering analog circuits, with each capable of outputting up to 30V @
3A; the third channel, typically used for powering digital circuits, can
output up to 5V @ 3A. (In contrast, competitive three-channel supply's
analog outputs are limited to just ±[email protected].) These maximum output
levels, combined with voltage setting and reading resolution of 10mV and
current setting and reading resolution of 1mA, allow generating a wider
range of output power and reading a wider range of load currents.
High Voltage and Current Output and Readback Accuracy With
basic voltage setting accuracy and voltage readback accuracy of 0.06%
for each output channel, Model 2231A-30-3 users can be confident the
exact voltage they program for any channel is the level applied at the
output terminals. It also offers 0.2% basic current setting and readback
accuracy and less than 5mVp-p ripple and noise to ensure high quality
load current measurements.
Isolated and Independent Outputs for Greater Testing Flexibility than
Competing Supplies Each output channel is completely isolated,
so the Model 2231A-30-3 can power three isolated circuits with different
reference points, eliminating the need for multiple supplies. Many
competitive multi-channel supplies do not offer isolated outputs on the
high voltage channels and cannot properly power isolated circuits. In
addition, because the Model 2231A-30-3's outputs are isolated, one
output can be turned effectively into a negative source by connecting
its high terminal to the common reference point of a bipolar circuit.
The low terminal of a second output can be connected to the same common
reference point. The result is a positive output and a negative output.
If the two 30V channels are used in this configuration, both outputs can
be changed at the same time by using the supply's tracking function.
That allows varying both channels at the same time while keeping the
magnitude of their outputs the same.
Each channel can also be turned on or off independently, so the Model
2231A-30-3 can be used to power up a circuit that requires turning on
multiple voltage levels in a specified time sequence. It can also power
up both the analog circuitry and the digital circuitry of a printed
circuit board or a complete device, all with the same instrument. A
programmable timer allows setting up a test to run unattended, turning
off the outputs after a specified interval.
Reconfigurable Outputs and Easier-to-Understand Output Displays For
applications that require supplying more than 30V or 3A, the power
supply's 30V outputs can be combined by wiring them in series to produce
a 60V output or wiring them in parallel to produce a 6A output. To make
this easy for the user, series and parallel modes manage control of the
two outputs and display the total voltage and current outputs for the
combined channels.
Optional USB Control An optional adapter provides the
flexibility to control the supply manually or remotely. The Model
2231A-001 USB Adapter allows controlling the supply via a PC's USB
interface, then transferring readings from the outputs to the PC so they
can be combined with other test data to allow a more thorough analysis
of DUT performance.
Flexible Operation and High Ease of Use A variety of
features enhances the operating versatility and simplify operation of
the new supply:
-
Frequently used instrument settings can be saved to one of 30 internal
memory locations to save time when conducting repetitive tests.
-
A rotary knob with adjustable step size simplifies studying a DUT's
response to voltage or current changes. A numeric keypad offers an
alternative method of entering values precisely.
-
Voltage and current outputs for all channels are shown simultaneously
on the bright vacuum fluorescent display, unlike competitive units,
which can display only one channel at a time.
