Compact AC Power
With European and US outlet sockets to connect the load, the 801RP and 1251RP
programmable AC power sources are ideal for a wide variety of applications.
Universal, Power Factor Corrected (PFC) input allows these products 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 covers 500 Hz, making these products ideal for commercial
and defense avionics applications. A built in current measurement function
eliminates the need for an external current shunt or transformer. Load current
can be read directly on the large LCD display to 0.1 A. For additional protection,
a current limit function can be set from zero to the maximum current rating.
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 135 Vrms and 270 Vrms, provide maximum
current at the required voltage. The output frequency can be varied from
16 Hz up to 500 Hz to cover both avionics and utility power applications.
IEC 1000-3-2 Test Applications
The low total harmonic distortion of the output makes the 801RP and 1251RP
suitable AC sources for IEC 1000-3-2 Current Harmonics pre compliance testing.
Loads requiring up to 4.6 Arms at 230 Vrms with peak currents up to 12 A
can be tested with the 1251RP while the 801RP can supply up to 3.0 Arms.
This covers many loads that fall under the IEC standard.
Quality Control
For product quality test applications, the 801RP and 1251RP 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, both units are well
suited for commercial and defense avionics applications. Both unit can easily
be integrated into avionics ATE systems.
Functional Design
The small form factor and low weight of these units make them 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 3.5 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 RP Series units can be
outfitted with both GPIB and RS-232C using the -IF option. A front panel lock
out mode is supported on both models if operator interaction with the AC source
is not required or desired. NOTE: Model 801RP is only available WITH
option -IF (801RP-IF).
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, 801RP and 1251RP
units are 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. (Note: Transient
control does not apply to output phase angle).

 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 801RP and 1251RP 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 10 ms or longer voltage dropouts
- Measure rms current, voltage and apparent power
- 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
- Turn output on and off
