Programmable Functions Allow Simulation of Complex Line Conditions
The broad range of programmable functions available with the L-Series allow you to test for virtually any line occurrence. The -P and -PT programmable controllers are equipped with 16 transient registers that can be programmed from the front panel keypad or the IEEE-488 interface. Here are some capabilities of the L Series programmable controllers:
Set the voltage on each phase
individually with 0.1 volt resolution.
Set the frequency with 4 digit resolution.
Set phase angles for phase B and C with respect to phase A
with 0.1 degree resolution.
Set a power surge or blackout from 1 mSec to 2 hours duration
to simulate power utility generation
and distribution problems.
Set the starting point of the
sine wave anywhere from 0 to
360 degrees with 0.1 degree
programming to test for maximum
load in-rush current.
Select sweep of voltage,
frequency and/or phase angle to
test for catastrophic failure and
brown-out conditions.
Program voltage dropouts at
any phase angle, either by time or cycle count, to test for correct
operation in the vicinity of a
heavy intermittent load such as
an air conditioner or refrigeration
plant.
Select internal or external
synchronization signal and
measurement strobe function to
ensure reliable operation in a
complex measurement system
that includes an oscilloscope or
other recording device
Save custom setups in nonvolatile
memory for easy recall
(front panel or bus)
Link memory locations for
complex setup sequencing that
can cover many hours for
complex multi-line standard burnin
testing.
Included Windows™ Software Eases Transient Programming
All L Series AC sources shipped with
a programmable controller (-P, -PT or
HGA) include a Windows™ Graphical
User Interface (GUI) program. The GUI
supports all functions and capabilities
of the L Series controller used. The
following tasks can easily be performed
through this graphical user interface
using the IEEE-488 interface (National
Instruments PC IEEE controller required):
Control all output parameters
such as voltage, current limit,
phase and frequency.
Compile lists of transient programs on disk for quick recall
and execution
Measure and record key output
parameters such as volt rms,
current, peak current, real power,
and power factor.
Run RTCA/
DO160C
(requires option -
160) or MIL-STD
704D tests
(requires option -
704)
Monitor remote
control commands
over the
bus using the
built in command
viewer window to
quickly learn how
to program the L
Series yourself.
Drivers for popular programming environments such as LabViewT or LabWindows/CVIT are available as well for custom software development If needed, the front panel can
be locked out to prevent operator
intervention during test runs.
