Programmable DC Electronic Loads
8600 Series
The 8600 Series programmable DC electronic
loads provide the performance of modular system
DC electronic loads in a compact benchtop form
factor. With fast transient operation speeds and
high 16-bit measurement resolution, these
standalone DC loads can be used for testing and
areas for quick system recall. All load parameters
such as voltage, current, slew rate, and width
can be set via the front panel or programmed
remotely. The 8600 Series provides standard
USB (USBTMC-compliant), GPIB, or RS-232
serial interfaces for remote communication.
evaluating a variety of DC sources such as DC
power supplies, DC-DC converters, batteries,
battery chargers, and photovoltaic arrays.
To ensure the reliability of your testing, the 8600
Series provides a power-on system self-test and
numerous protection features: overtemperature
The DC loads can operate in constant current
(CC), constant voltage (CV), constant resistance
(CR), or constant power (CW) mode and be
(OTP), overvoltage (OVP), overcurrent (OCP),
overpower (OPP), and local/remote reverse
voltage (LRV/RRV) protection.
configured to provide a dynamically changing load
to the DC source with fast load switching times.
Versatile internal, external, and remote triggering
options allow the dynamic load behavior to be
synchronized with other events.
Special Applications
The 8600 Series provides a built-in battery test
mode to measure the ampere-hour (Ah)
characteristic of a battery and a unique CR-LED
Increase productivity by saving your test
parameters into any one of the 100 memory

Flexible operation
Transient operation
A
A level

Slew Rate
t
Transient operation enables the load to periodically
switch between two load levels (A/B). A power
supply’s regulation and transient characteristic can
be evaluated by monitoring the supply’s output
voltage under varying combinations of load levels,
duty cycle, and slew rate. The 8600 Series can
simulate these conditions in CC, CV, CW, and CR
mode.

Not limited to just switching between two levels,
list mode lets you generate more complex
sequences of input changes with several different
levels. Up to 7 groups of list files can be saved
and executed in CC mode via internal or external
trigger. Each list can contain up to 84 steps with
varying slew rates and a minimum width time of
20 μs per step.
Low voltage operation
The 8600 Series can operate at low voltages for applications such as fuel cell and solar cell testing.

The 8600 Series can execute multiple test
sequences in automatic test mode. Up to 100
different sequences can be linked to run steps of
various operating modes and loading conditions.
Each sequence can also be programmed with
upper and lower limit Pass/Fail criteria. When
applied in production testing, you can easily
judge whether the test parameters of your
devices are within the specification limits and
adjust your process according to the Pass/Fail
verdict.

The built-in battery test function uses CC mode
to calculate the battery capacity using a fixed
current load discharge. Users can specify cut-off
voltage level, capacity level, and time stop
conditions.
Built-in rise and fall time measurement
External analog programming and
monitoring interface
In addition to front panel and remote interface
control, current values can also be programmed
with an analog control signal. The electronic
loads can be externally controlled from zero to
full scale with a 0-10 V input signal. A BNC
output is available on the rear for monitoring
the current with a 0-10 V output signal.

at a specified voltage level.
Application software
PC software is provided for front panel emulation,
generating and executing test sequences, or
logging measurement data without the need to
write source code. Additionally, this application
software integrates with NI Data Dashboard for
LabVIEW apps, which allows users to create a
custom dashboard on a tablet computer or
smartphone to remotely monitor 8600 Series
DC loads via this PC software.
■ Remote monitoring on iOS, Android or
Windows 8 compatible tablets or

■ Create an unlimited number of external list
files to be executed from PC memory

Oscilloscope display
The 8600 Series can measure the rise or fall time from a specified start and stop voltage level of
the measured input without the need for an oscilloscope. This function can also be used as an
internal timer to count how long the input has been enabled.

In CC mode, users can control the rate or slope

or as fast as 2.5 A/µs depending on the model
and selected current range.

Slew Rate
(1)
Fast pulse trains with large transitions may not be achievable.
(2)
The slew rate specifications are not warranted, but are descriptions of typical performance. The actual transition time is defined as the time for the input to change from 10% to 90%, or vice versa, of the
programmed current values. In case of very large load changes, e.g. from no load to full load, the actual transition time will be larger than the expected time. The load will automatically adjust the slew rate to fit within the range
(high or low) that is closest to the programmed value.
