Compact AC Power
Offering simple rotary front panel controls, the 2001RP Programmable AC Power
Source is ideally suited for a wide range of applications. Selectable input
voltage ranges allow this product to be used anywhere in the world to provide
a convenient source of variable utility power for the testing and evaluation
of domestic and commercial equipment. All common line voltage and frequency
combinations are covered. In addition, the frequency range extends to 5,000
Hz, making these products ideal for commercial and defense avionics applications.
Accurate measurement functions are available as an option to eliminate the need
for external test equipment in many test setups. Voltage, current, peak current,
power, and power factor can be read directly on the large LCD display or over
the bus. Overload protection is provided standard using a programmable current
limit function.
Easy To Use Controls
Front panel digital rotary encoders are used to set voltage and frequency. These
controls have an analog feel, with the precision and reliability of digital
circuits. Settings are read directly on the large high contrast LCD displays.
Dual output voltage ranges of 150 Vrms and 300 Vrms, provide maximum current
at the required voltage. The output frequency can be varied from 16 Hz up to
5,000 Hz to cover commercial, avionics and defense power applications.
IEC 1000-3-2 Test Applications
The low total harmonic distortion of the output makes the RP Series suitable
AC sources for IEC 1000-3-2 Current Harmonics pre compliance testing.
Quality Control
For product quality test applications, the 2001RP can be used to simulate
line conditions found anywhere in the world. This ensures products destined
for export will operate as designed.
Avionics Applications
As an affordable and reliable source of 400 Hz AC power, the 2001RP is well
suited for commercial and defense avionics applications.
Functional Design
The small form factor and low weight makes the 2001RP convenient to
use in a variety of locations. Removable rubber feet protect the work surface
if the unit is used in a bench top mode. The 5.25 inch height saves valuable
rack space when compared to conventional AC power sources at this power level.
 Remote or Local
Operation
For automated test equipment (ATE) applications, the 2001RP can be outfitted
with both GPIB and RS-232C using the -OP1 option. A front panel lock out mode
is supported on both models if operator interaction with the AC source is not
required or desired.
The optional remote control interface allows complete control of all AC source
functions and provides measurement data to the controller. This allows the RP
Series AC source to be used as a low cost AC test system. A Windows™ Graphical
User Interface (GUI) program is included with the interface option. Automatic
power cycling and transient generation is made possible with the use of this
GUI program. The GUI output control, measurement and transient screens are shown
here. For quality assurance applications, measured voltage, current and VA readings
can be logged to disk for documentation and analysis purposes. All data recorded
is time stamped to create a complete history of each test run. Up to eight often
used front-panel setups can be stored in non-volatile memory for quick recall
from the PC controller through the interface. With enhanced capabilities such
as data logging to file and Dynamic Data Exchange to other Windows programs,
many applications can be addressed without the need for writing custom code
 Extensive
Transient Control
With the addition of the remote control interface option, the 2001RP is capable
of producing transients with a high degree of user programmability. Setting up
transient programs is facilitated by a Windows Graphical User Interface program
that allows amplitude, frequency and event duration to be programmed from a PC.
Time resolution is 1 ms (0.001 sec) with a minimum time interval ranging from
10 to 40 ms, depending on the transient type. Transient programming allows the
effects of common line disturbances such as voltage surges, sags, drop-outs and
frequency fluctuations on the unit under test to be evaluated. Voltage drop out
transients can be programmed at random phase angles or at 0, 90, 180 and 270
degrees. |
|  AC Line Immunity Testing
Special application support is provided for pre-compliance IEC 1000-4
immunity testing, specifically IEC 1000-4-11 Voltage Dips and Interruptions,
IEC 1000-4-14 Voltage Fluctuations (draft) and IEC 1000-4-28 Frequency
Variations (draft). All IEC test windows provide on screen editing of
test parameters to meet various product category test requirements. These
test sequences can be saved to disk, enabling a library of IEC test sequences
to be created. Generic test files are supplied with the program for immediate
use. After a test run, a complete test report including the user provided
equipment under test data and test parameters used can be printed or saved
to disk.

SCPI Protocol Programming Commands
All functions of the RP Series are completely programmable over the GPIB or RS-232C
bus. For example, the following tasks can be performed over the bus:
- Set voltage to any level
- Change frequency
- Generate voltage dropouts, sags or surges
- Measure TRMS current, peak current, crest factor, TRMS voltage,true power,
apparent power and power factor
- Recall eight complete instrument setups from non-volatile memory with a
single SCPI command
- Reset the instrument
- Adjust current limit value
- Lock the front panel to prevent operator interference
- Switch between high and low voltage range
- Drop output voltage at specific phase angles for specified durations
- Turn output on and off
