phase), and SW5550. The 5250A three phase
unit can be switched to single phase or vice
versa, simply by menu selection (and appropriate
output wiring changes). The SW Series is factory
upgradable from 1750 VA to 3500 VA or 5250
VA. Utilizing a master/slave arrangement,
SW5250A can be paralleled for incrementally
higher power requirements, e.g. one master/one
slave= SW10500 (10.5 kVA). As many as 3 slave
chassis may be paralleled with a master to form
a 21 kVA system. Options include input power
factor correction, measurement capability, plus 5
and 26 VAC auxiliary outputs.
Waveshape Library
There are 50 factory-supplied waveshapes in the
SmartWave. Following are examples of the types
of waveshapes in the library:
• Sine wave
• Square wave
• Triangle wave
• Clipped sine waves
• Sine waves with spikes
• Fractional dropouts
• Sine wave with dropout (0V from 0° to 90°)
• Sine waves with ±1-50% DC offset
• ±DC with 3% and 10% ripple
• Fourier square waves with harmonics
• Taylor series waves
• Sine wave with noise at zero crossing
As shown by this photo, the SmartWave can create time coincident spikes on 3 phases, fractional or multi-cycle dropouts, sags and surges,
waveforms distortion, DC and noise.

APPLICATIONS
The SmartWave is designed for testing today’s
complex electronics, including avionics,
telecommunications and commercial electronics
requiring low profile, light weight power supplies.
Other applications include:
• Testing for real world power conditions using
different waveforms on all 3 phases (including
DC)
• Load susceptibility testing with sequence or
event programming and multiple voltage
harmonics
• Power line disturbance simulation testing
• MIL-STD-704, DO-160 and ABD100 avionics
testing
• Power supply testing for AC-DC, DC-DC
converters and UPS’s
• Fluorescent lighting characteristics testing (IES
LM-41-1985)
• Transients on 12 & 24 VDC for automotive
applications

SMARTWAVE CONTROL SUITE (SWCS)
The SmartWave™ Control Suite is a complete
Windows®-based graphical GPIB control software
package for the Elgar SmartWave (SW) and SWAE
product lines. It provides a simple, yet powerful,
method to actively control the SW, create and
edit waveforms and sequences, as well as log
measurements to your PC. Comprised of six
interactive windows (or tabs) SWCS provides the
following SW control features:
Program Settings: Direct setting of most common
parameters such as voltage, frequency, current
limit, phase angle and waveform type.
Measurements: Provides a strip-chart like
recording of up to four measurements. Results
may be viewed and logged to a file.
Waveform: Allows creation and editing of
waveforms using several powerful methods,
including defining a waveform by harmonic
content.
Sequence: Simplifies setup, debugging and
running of waveform sequences.
Instrument: Provides setting and modifications
to configuration changes such as voltage range,
coupling and shutdown method.
System: Gives user access to less common
features of the SW, as well as allowing direct GPIB
command control.
System Requirements:
• Pentium II 500Hz or greater
• 256MB RAM
• 500GB available hard disk space
• Microsoft Windows 95/98/NT/W2K/XP
• National Instruments GPIB card or GPIB-ENET
(GPIB to Ethernet converter box) or GPIBPCMCIA
