Multi-Range Programmable DC Power Supplies
9115 Series
1200 W Multi-Range DC Power Supplies
Any 9115 series model can replace several supplies on your bench or in your rack. Unlike conventional
supplies with fixed output ratings, these multi-range power supplies automatically recalculate voltage and
current limits for each setting, providing full output power in any Volt/Amp combination within the rated
voltage and current limits.
For benchtop applications, this series provides a numerical keypad for direct data entry along with
convenient cursors and analog style knobs to quickly make incremental voltage or current changes. System
integrators benefit from the standard USB (USBTMC-compliant), RS-232, GPIB, and RS-485 interfaces
supporting SCPI commands. Alternatively, users can control the power supply, execute test sequences or
log measurements using the provided PC software application. This software also integrates with Data
Dashboard for LabVIEW apps enabling iOS, Android or Windows 8 compatible tablets or smart phones to
remotely monitor select measurement indicators.
The 9115-AT provides automative power test waveforms compliant to DIN 40839 and ISO 16750-2
standards that can simulate common test conditions for electrical and electronic devices installed in
automobiles.

Multi-Range Operation
The multi-ranging feature of the 9115 Series
offers exceptional flexibility by providing any
combination of the rated voltage and current up
to the maximum output power of the supply.
These wide ranges of voltage and current allow
users to replace multiple supplies on a bench or
system rack.

Programmable voltage rise/fall times
The power supply is capable of programming the
slope of the output voltage during changes
etween voltage settings by allowing users to set
b
the rising and falling edge times of the voltage.
Master/Slave operation
More than one unit of the same power supply
model can be connected in parallel or series
onnection to increase the overall current or
c
voltage output respectively. Using the RS-485
interface, the power supplies can operate in
master/slave mode. In this mode, the master unit
can control all other power supplies connected
in parallel or series. Additionally, the RS-485
interface can be used for multi-unit control of
up to 31 daisy chained units.
Test sequence execution in list mode
The list mode feature lets users store, recall, and
run program sequences in the power supply’s
internal memory. A total of 10 steps can be
configured for each sequence (up to 10). These
sequences can then be saved into a program
configuration that can run one sequence after
another, which allows for a maximum of 100
steps in one program configuration.
External analog control interface
The power supply output voltage and current can
be controlled from zero to full range by either
external DC voltage sources (0-5 V or 0-10 V)
or resistances (0-5 kΩ or 0-10 kΩ). The DB25
analog control interface also provides a source
for monitoring the voltage and current output.
Parallel Configuration
Series Configuration
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 smart phone to remotely monitor 9115 series power supplies via this PC software.
• Remote monitoring on iOS, Android or Windows 8 compatible tablets or smart phones via NI Data Dashboard for LabVIEW apps. Quickly develop a custom
dashboard consisting of one (smart phone) or several (tablet) indicators, charts or gauges to monitor your power supply.
• Log voltage, current and power values as well as time stamp, CV/CC and output status.
• Save and load list files to/from the power supply’s internal memory.
• Create an unlimited number of external list files to be executed from PC memory. Save and recall list files to/from the PC.

Model 9115-AT Automotive Test Functions
In order to ensure electronic systems used in a vehicle are able to function
in an automotive environment, automotive component manufacturers test
electronic modules to industry standards. The 9115-AT provides built-in
simulations compliant to these automotive test standards to help automate
and speed up development time.
SO 16750-2
I
This standard applies to electric and electronic systems/components
for vehicles. It describes the potential environmental conditions and
specifies tests and requirements recommended for the specific mounting
location on/in the vehicle. These test simulations include measurement
of discontinuities in supply voltage, voltage drops, tests applicable to
equipment with reset functions, and tests to insure modules do not
malfunction during an engine start routine with cranking.
Simulate the effect when a conventional fuse element
melts in another circuit.
DIN 40839 (ISO 7637)
This standard insures EMC (electromagnetic compatibility) in road vehicles by
injection of supply line transients. The 9115-AT can output a 12 V or 24 V
system voltage sequence, which simulates the behavior in supply voltage
reduction caused by an engine starter motor circuits (Fig. 1).
