Model 801RP / 1251RP

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 of the UUT (Unit Under Test)
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 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 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.

801RP / 1251RP - Easy Transient Programming

Drop transient causes output voltage to
drop to zero for a user specified period.

Voltage Surge transient causes output
voltage to surge

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.

Remote or Local Operation

For automated test equipment (ATE) applications, the RP Series
units can be outfitted with both IEEE-488 and RS232C 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.

SCPI Protocol Programming Commands

All functions of the 801RP and 1251RP are completely program­mable over the IEEE-488 or RS232C 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

Frequency Sweep transient at a user
specified rate.

Voltage Sweep transient causes output
voltage to change at a programmed rate.

Application Software

Windows 98™ or Windows 2000™ application software is included
with the remote control interface option. This easy to use graphical
interface program provides complete control over all instrument func­tions using either the RS232C or IEEE-488 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.

Free Windows™ Graphical User Interface
software included with interface option.
