Elgar SW5250 AC Power Supply
The Elgar SW5250 uses transformerless, direct coupled amplifiers and a true arbitrary waveform generator based controller. This technology allows the user to create, edit and generate complex SmartWave™ waveforms with high DC content for critical ATE and power line disturbance simulation testing.
The SW5250 can create complex waveforms with high DC content for simulating real world power irregularities, including phase controlled sub-cycle or multi-cycle dropouts, spikes, sags, surges, frequency excursions, plus frequency and voltage ramps (sweeps). The unit can also generate clipped waveforms, harmonic distortion, high current inrush and other complex waveshapes.
