Flexibility in Power Ranges
The SmartWave series includes the SW 1750 (single
phase only), SW 3500 (single or dual phase), and SW
5250A. 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, SW 5250A can be paralleled for
incrementally higher power requirements, e.g. one
master/one slave = SW 10500 (10.5 kVA). As many
as 3 slave chassis may be paralled 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
Applications
The SmartWave is designed for testing today’s
complex electronics, including avionics,
telecommunications and commercial electronics
requiring low profi le, 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)
SWCS is a Windows based
software package for computer
control of the SmartWave Series
and SWAE AC power sources.
With the SWCS you have
complete control of the instrument
including programming, waveform
selection, creation and sequencing.
SWCS enhances the standard
SmartWave features with an
additional harmonic waveform
analysis capability with data logging
features for all measurements.
