B&K Precision 9833B AC Power Supply

Overview

The B&K Precision 9833B is a programmable AC power source that delivers 0–300V, 0–30A, and up to 3000VA in a compact 3U form factor. It supports AC, DC, and AC+DC output coupling modes with low total harmonic distortion meeting IEC 61000-3-2. The unit features comprehensive measurement capabilities including Vrms, Arms, Vdc, power factor, and true power.

The 9833B can be configured for 3-phase power by connecting multiple units with optional 3-Phase sync adapters. It supports a wide frequency range of 45–600 Hz in 3-phase mode and offers multiple waveform options including sine, square, clipped sine, and custom user-defined arbitrary waveforms.
