The BK Precision 9803B Programmable AC Power Source, 300V/6A, 750 VA, 120VAC Line Input delivers up to 750 VA through its universal line output terminal on the front and output connector on the rear. The output can be varied from 0 to 300V with 0.1V resolution, with adjustable start and stop phase angles from 0 to 360 degrees and maximum current of 6A. The output frequency can be adjusted from 45 Hz to 500 Hz. The bright VFD display shows Vrms, Irms, Ipeak, frequency, power factor (PF), apparent power, true power and elapsed output time.

These AC sources provide a power line disturbance (PLD) simulator, list mode, and sweep mode for simulation of common power grid faults and disturbances. A built-in dimmer function is also available for testing motors and LEDs.

List mode can be used to generate sequences of waveforms such as surges, sags, and frequency disturbances. The programmed list can be triggered from the front panel or via BNC connector on the rear. Standard USB, RS232 and LAN interfaces can be used to remotely control the source via a PC. Free application software and LabVIEW driver are available to reduce programming time and increase productivity.
