SW 5250A•SW 3500A•SW 1750A General Description
Operation Manual 1-3
The SmartWave sources are true DC as well as AC power supplies. Up to 312 VRMS
are available in AC or AC+DC modes. Multi-phase models can be switched to single or
three-phased operation via the front panel or the GPIB.
A wide frequency range of DC or 40 Hz to 5 kHz is available for a broad array of
applications. Utilizing the latest in AC switch mode technology, the SmartWave has
less than -60 dB of noise and ripple with total harmonic distortion (THD) of <0.5% to
500 Hz. A crest factor of 4.0 provides high peak-to-RMS current capability. An optional
power factor correction (PFC) of .99 is also available.
