9830B Series Programmable AC Power Sources
Conducting pre-compliance testing? Simulating common grid faults, voltage sags, frequency and phase disturbances or evaluating transformers, TRIACs, SCRs, and passive components? If so, B&K Precision’s 9830B Series programmable AC power sources have the reliability and features you need. With an easy-to-use interface in a compact 3U form factor, these power sources deliver high performance with low total harmonic distortion.

Positive and negative DC offset voltages expand the AC capabilities to operate in DC and AC+DC output coupling modes. Users can select built-in and user-defined harmonic waveforms or select from standard sine, square or clipped sine outputs.

Achieve 3-phase power by connecting 3 units of the same model in a master-and-slave configuration using optional 3-phase sync adapters. The frequency range is adjustable from 45 to 600 Hz in 3-phase mode.

Choose from two models and an adapter kit.
