Description
Arbiter Systems®, Inc.
Models 931A, 930A, and 929A, with state-of-the-art
PowerDSA™ Digital Signal Analysis, make more
measurements, more accurately, more easily, and at a lower
price than ever before. Basic accuracy of 0.05% of reading
and 0.05° phase, harmonic analysis, and full three-phase
capability are standard on all three models. The 930A and
931A also incorporate full two way serial communication for
use in power quality trend monitoring, and for complete
power system analysis the 931A also includes a transducer
calibration and timer features.
The Arbiter Systems®,
Inc. Model 930A Three Phase Power Analyzer is an economical
alternative to the Model 931A Power System Analyzer when the
dc voltage measurement, transducer calibration and timer
features are not required. The Model 930A has the same ac
accuracy as the Model 931A with PowerDSA™ Digital Signal
Analysis. The Model 930A with serial communication
capability and available application software, in
conjunction with a laptop computer, is a valuable tool for
use in power quality trend monitoring, as well as being a
complete diagnostic tool for use in the substation and
industrial power environment.
The Arbiter Systems®,
Inc. Model 929A Three Phase Power Meter is an economical
alternative to both the Model 931A Power System Analyzer and
the Model 930A Three Phase Power Analyzer when serial
communication, dc voltage measurement, transducer
calibration and timer features are not required. The Model
929A has the same ac accuracy as the Model 931A with
PowerDSA™ Digital Signal Analysis, and is a complete
diagnostic tool for use in the substation and industrial
power environment.
Portability
Thanks to the high level of
integration made possible with PowerDSA™, our
instruments are lighter, smaller, and run longer on a charge
than any others in this class. Smaller than a lunchbox and
weighing only 5.8 kg (12.8 pounds), you can take any of our
PowerDSA™ instruments with you wherever you go,
operate it continuously for a full 8-hour shift from its
internal sealed lead-acid battery, and then recharge it
completely in eight hours.
Safety
Built in a rugged, non-conductive
high-impact polyethylene case, and with all inputs isolated
from instrument common by transformers, optical isolators or
high-value series resistors, these instruments were designed
with safety in mind. A front-panel ground terminal provides
a sink for leakage currents.
Convenience
The outstanding features do not end with light weight,
measurement flexibility, or unprecedented accuracy. Many
other user conveniences have been added to ease your
workload.

memory (or an RS-232 printer with Models 931A and 930A),
time and date tagged from the internal real-time clock.
Options
and Accessories
Available options include an
additional 16 megabytes of internal data memory to provide
storage for data logging (not available for the Model 929A),
931A Application Software, 930A Application Software, an
adjustable tilt handle/bail assembly for the transit case.
Available
accessories include a 400 Amp 20:1 precision CT, mounting
brackets to provide for mounting of CT's inside the cover of
the transit case, a wide selection of test leads, and an
RS-232 cable.
All of this, and
more, is ready to help you do your job better and in less
time. Put an Arbiter Systems® Model 931A, Model
930A, or Model 929A, all with PowerDSA™ Digital Signal
Analysis to work for you soon! |
