Product Overview
The Smart Wave (SW) series of AC power sources offers powerful waveform creation for ATE and power line disturbance simulation testing. Three separate arbitrary waveform generators enable the Smart Wave to create independent, complex waveforms on all three phases simultaneously. The Smart Wave is designed to meet waveform requirements including DC contents (up to 312V), low distortion (THD 0.25% to 100Hz), low noise and ripple, plus full compliance testing to EMC standards. At only 8-3/4 inches high for the SW 5250A, the Smart Wave delivers the most power in the smallest package. It weighs only 127 pounds, and offers the highest power density in the industry. The SW Series is expandable from 1.75kVA to 21kVA. Unlike other AC power sources, the Smart Wave delivers full rated power to 45C.
AC AND/OR DC
A direct coupled, transformerless design allows AC and DC on separate phases or on the same phase. The Smart Wave can be used as a true DC power supply. High DC content waveforms (up to 312 volts) can be created with no de-rating of output power, even with 100% reactive loads. This can eliminate the need for a separate DC supply.
GRAPHIC LCD DISPLAY
Display The Smart Wave has a graphic LCD display for previewing and confirming the waveforms before connecting the output to the load. The menus are easy to follow with the overlay paging format. Users can select menus, slew voltage and frequency with a handy knob on the front panel. Front panel signal and sync outputs allow three phase scope viewing.
Features and Benefits
Powerful Wave Shape and Waveform CreationThe Smart Wave can easily create fractional or multi-cycle dropouts, spikes, surges, sags and distorted waveforms from the front panel. To simulate these complex real-world power occurrences, the Smart Wave comes with a library of 50 built-in wave shapes of their own design. Output voltages are created by adding amplitude, frequency and other parameters to the wave shapes. The user can also create over 50 custom front panel setups with all parameters included and store them for quick recall, making the Smart Wave ideal for manual testing.
POWERFUL DSP2 WAVEFORM PROGRAMMING
Waveform programming is easily accomplished using the optional DSP PC software. The software allows freehand creation of waveforms, using a mouse or mathematical expressions. Real-world waveforms can be uploaded and modified when using a digital scope. The waveforms can then be downloaded to the Smart Wave via GPIB and output to exactly simulate real-world conditions.
SEQUENCE PROGRAMMING
Complex sequence or event programming is easy with time or cycle based transient segments. The sequence library is made up of a total of 1000 segments stored as labeled sequences. A sequences of up to 100 segments using up to 32 different wave shapes, arranged in any combination, can be run at any one time The 32 wave shapes can be selected from the 50 factory supplied and 50 user created wave shapes. By setting the time or number of cycles for each segments, the user can create waveform sequences that allow automatic testing for most any standards.

FLEXIBILITY IN POWER RANGES
The Smart Wave 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 upgradeable 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 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. The Smart Wave is designed for testing today's complex electronics, including 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
WAVESHAPE LIBRARY
There are 50 factory-supplied wave shapes in the Smart Wave. Following are examples of the types of wave shapes 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
Smart Wave Control Suite (SWCS)
SWCS is a Windows based software package for computer control of the Smart Wave 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 Smart Wave features with an additional harmonic waveform analysis capability with data logging features for all measurements.
