The SmartWave™ Series (SW) of AC power sources offers powerful waveform creation for ATE and power line disturbance simulation testing. Three separate arbitrary waveform generators enable the SmartWave™ to create independent, complex waveforms on all three phases simultaneously. The SmartWave™ is designed to meet waveform requirements including DC content (up to 312V), low distortion (THD 0.25% to 100 Hz), low noise and ripple, plus full compliance testing to EMC standards.

At only 8-3/4 inches high for the SW5250A, the SmartWave™ 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 1.75 kVA to 21 kVA. Unlike other AC power sources, the SmartWave™ delivers full rated power to 45°C.
