Isolated and independent outputs provide maximum flexibility
Each output channel of the Series
2230G high power supplies is both
independent of the other channels
and electrically isolated from the
other channels. Therefore, these
supplies can power circuits that are
optically isolated or transformer-
isolated from each other and have
different reference points. The isolated
channels eliminate the need for a
second power supply to power one of
the isolated circuits.

Power two isolated circuits with isolated
output channels.
Furthermore, each channel can be
independently controlled so that
channels can be independently
turned on and turned off at any time.
These power supplies can power up
a circuit with multiple voltage levels,
such as a digital circuit with a 1.2 V
microprocessor and FPGA, a 1.8 V
memory, and 3.3 V digital I/O lines,
in a sequence that safely brings up
the lower voltages before the higher
voltages are powered.

Use the tracking function to power a DUT’s
bipolar circuits and test the DUT over its
specified operating voltage range.
Allowing control over each individual
channel minimizes noise in the circuit.
When a test requires only one or
two channels, the unused channels
can be turned off to minimize the
total output noise. Thus, circuits that
are sensitive to noise on their DC
power lines can be powered with the
minimum output noise from the Series
2230G power supplies.
Combine the two 30 V outputs of the
2230G-30-3 and the 2230G-30-6 in
series to output up to 60 V with either
3 A or 6 A load current capacity.
When higher load current is needed,
either two or all three channels of
each supply can be combined in
parallel. The 2230G-30-6 can supply
12 A from its two 30 V channels. If the
test circuit requires only a maximum
of 5 V, then all three channels can
be connected in parallel to supply up
to 15 A. The Series 2230G supplies
have display and control functions
to simplify the task of combining
channels in series and parallel. The
display indicates whether the series
or parallel mode has been selected
and shows the total series voltage or
parallel current output. The supply
also manages the channels to
ensure that each channel outputs an
equivalent value.
For powering bipolar analog circuits,
channels 1 and 2, the 30 V and
60 V channels of the Series 2230G
supplies can be connected to power
a positive and a negative circuit. The
supplies have a tracking mode so
that the outputs of both supplies can
be simultaneously changed with one
control operation. The magnitudes
of the two tracked channels either
change together or change in a
user-defined ratio when the voltage
is changed. Thus, a bipolar circuit,
module, or device can be easily
tested over its specified voltage
operating range.

Combine 30V channels in series to extend
voltage output to 60 V. Combine channels in
parallel to extend current output capacity.
For example, combine all three channels of a
2230G-30-6 to output up to 15 A.
