A Greater Measure of Confidence
The Series 2200 Multi-channel Programmable DC Power Supplies combine two and three channels
of output power to cost-effectively characterize and test a wide range of devices, circuit boards,
modules, and products that require more than one power source. The Model 2220-30-1 supply
provides two channels, with each channel capable of outputting up to 30V and up to 1.5A. The Model
2230-30-1 includes two 30V/1.5A channels and adds a 6V channel with up to 5A output for power-
ing digital circuits. The Series 2200 Multi-channel Power Supplies offer an excellent combination of
performance, versatility, and ease of use to maximize the information from characterization or test as
quickly and as easily as possible. They perform as effectively in automated test systems as they do in
manual instrument configurations.
Independent and Isolated Outputs
Since each channel in the Series 2200 Multi-channel Power Supplies is completely independent and
isolated from each other, these power supplies can be used to provide power to two circuits that are
optically isolated or transformer-isolated from each other and have different reference points. Their
isolated channels eliminate the need for a second power supply to power one of the isolated circuits.
Additionally, each channel can be independently controlled, so channels can be individually turned
on and turned off at any time. Thus, these power
supplies can be used to power up a circuit, such
as a digital circuit, that requires multiple voltage
levels that must be turned on in a specified time
sequence. Furthermore, a timer capability allows
the user to set up an unattended test and to turn
off the channels after a programmed time inter-
val to protect a device-under-test (DUT) from
potential damage due to the continuous appli-
cation of power beyond a recommended time
interval. Both isolated and independent chan-
nels provide excellent versatility and flexibility to
address a wide range of test applications.
Accurate Power Delivery to the Load
With basic voltage setting accuracy and voltage
readback accuracy of 0.03% for each channel,
the exact voltage programmed for any channel
is applied at the output terminals. Plus, the rear
panel connections for each channel include
remote sense terminals that compensate for volt-
age drops in the power supply leads. This helps to ensure that the correct voltage is delivered accu-
rately to the load terminals of the DUT. Many multi-channel power supplies do not provide remote
sensing, which degrades from overall system accuracy. Great accuracy is not limited to voltage; the
basic current setting and readback accuracy is 0.1%, providing high quality load current measure-
• Dual and triple output
models with two 30V/1.5A
(45W) channels and a 6V/5A
(30W) channel on the triple
output supply
• All channels are independently
controlled and have isolated
outputs for maximum flexibility
• All channels have remote
sensing to ensure that
programmed voltage is
accurately applied to the load
• Two 30V channels can be
combined either in series to
double output voltage or in
parallel to double output current
• 0.03% basic voltage output
accuracy and 0.1% current
accuracy ensure quality test data
• Low noise, linear regulation with
<3mVpp ripple and noise
• Voltage and current outputs
for all channels are displayed
simultaneously for easy
observation of each output state
• Keypad entry allows fast, precise
entry of output values
• Standard USB interface for
automated testing
