Descripcion
The RP Series consists of four models, 801RP, 1251RP, 2001RP and 2003RP. These units are ideal sources for general purpose AC power applications that require variable voltage and frequency at power levels up to 2000 VA. The 2003RP provides three phase output, all other models provide single phase output. With simple knobs used to set voltage, frequency and current limit, the RP Series provides an inexpensive source of AC power in a small and lightweight package. All RP Series power source models can be used in table-top mode or rack-mounted.
Controller Capabilities
The RP Series uses a precision digital sinewave generator to produce a low distortion output . Dual LCD readouts clearly display programmed settings for voltage, current limit and frequency. Load current is measured using true RMS sensing and can be displayed on the front panel as well. Adjusting voltage, frequency and current limit is accomplished using a set of digitally encoded rotary knobs. For ATE applications, both IEEE-488 and RS232C interfaces are available as an option.
Applications
The wide output frequency range of 16 Hz to 500 Hz (801RP and 1251RP) or 16 Hz to 5000 Hz (2001RP and 2003RP) make the RP Series suitable sources for both commercial and avionics applications. Dual voltage ranges provide maximum output current at any programmed voltage up to 270 Volt (801RP, 1251RP and 2003RP) or 300 Volt (2001RP). The built in rms. current measurement function eliminates the need for external current shunts or transformers to monitor load current. For front panel operation, the RP Series features simple and intuitive controls for setting voltage, frequency and current limits. Current drawn by the load can be read directly on the large LCD display with 100 mA resolution (801RP and 1251RP) or 1 mA resolution (2001RP and 2003RP). With the addition of the RS232C and IEEE-488 interface option, the RP Series sources can be used in automated test environments. Since the RP Series offers a high power to size ratio, requiring limited rack height, they can be used to upgrade existing ATE stations or build new ones.
The 2003RP provides three phase output and is a very cost effective AC power source for Avionics applications, especially in the -AV version.
The included PC control program (requires -IF option for 801RP and 1251RP or -OP1 option for 2001RP and 2003RP) supports transient generation to simulate real-world AC line conditions like brown-outs, voltage sags, surges and frequency fluctuations.
Remote Control
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¢â 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. If needed, the front panel can be locked out to prevent operator intervention during test runs.
The 2001RP and 2003RP offer additional features over the bus such as the ability to select the turn-on or turn-off phase angle of the output voltage. This capability, combined with the peak current measurement function, enables inrush current analysis of a unit under test.
AC Transient Generation
Transient programming is supported by the GUI program with user defined transient lists of up to 100 steps. Available transient functions are voltage step, voltage drop, voltage sweep, voltage surge/sag, frequency step, frequency sweep, frequency surge/sag as well as functions that combine both voltage and frequency changes. The intuitive Windows ¢â interface greatly facilitates creating and storing often used transient programs. Transient programs can be recalled from disk and executed once, continuously or a specified number of times. Editing functions such as delete and insert make it easy to modify or expand existing programs. This capability makes it easy to evaluate products for immunity to common AC line disturbances such as brownouts, surges, swells, sags and frequency variations.

Compact AC Power
Offering simple rotary front panel controls, the 2003RP programmable AC power source is ideally suited for a wide range of three phase AC power 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.
In addition, the frequency range extends to 5000 Hz, making this product ideal for a wide range of avionics and defense 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 for each individual phase output can be read on the large LCD display or over the bus. A programmable current limit function provides overload protection of the unit under test.
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 and measurements are read directly on the large, high contrast LCD displays.
Dual output voltage ranges of 135 V RMS L-N and 270 VRMS L-N, provide maximum current at the required voltage.
The output frequency can be varied from 16 Hz up to 5000 Hz to cover commercial, avionics and defense power applications.
Product Development
The precise voltage regulation and wide frequency range of the 2003RP, combined with its easy-touse front panel, make it a great three phase AC source for lab use.
Built in measurements may be added (option -OP1) to extend the unit’s usefulness for design applications of three phase AC products.
Avionics Applications
As an affordable and reliable source of three phase, 400 Hz power, the 2003RP is well suited for commercial and defense avionics applications. In addition to the standard 2003RP, a special avionics version is available (-AV option).
This version increases output current from 5.0 A RMS to 5.8 ARMS per phase at 115 V RMS. The 2003RP-AV uses high frequency output transformers and offers a lowest output frequency of 360 Hz. The weight of the 2003RP-AV is 10 % less than that of the standard unit.
Functional Design
The small form factor of the 2003RP makes it 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 low 5.25 inch height also saves valuable rack space when used in a rack and stack system.
Extensive Transient Control1
With the addition of option package -OP1, the 2003RP 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 1 to 40 ms, depending on the transient type. Maximum transient time intervals are 9999 seconds.
Transient programming allows the effects of common line disturbances such as phase loss, voltage surges, sags, drop-outs and frequency fluctuations on the unit under test to be evaluated.
Precision Measurements
For bench or automated test equipment (ATE) applications, the 2003RP can be ordered with the -OP1 option, offering both IEEE-488 and RS232C remote control interfaces as well as extended measurements.
These measurements are available from the front panel and over the bus. The 2003RP measurements can be calibrated over the bus, lowering cost of ownership.
SCPI Protocol Programming Commands
All functions of the 2003RP are programmable over the available IEEE-488 or RS232C interface. For example, the following tasks can be performed over the bus:
-
Set voltage and frequency to any level
-
Generate voltage dropouts, sags or surges
-
Measure TRMS current, peak current, crest factor, TRMS voltage, true power, apparent power and power factor
