The BK9803 from B&K Precision, and available from Farnell element14, is a 9800 series programmable AC power source.

This fully programmable linear AC source delivers a maximum of 750VA through the universal line output terminals on the front and the output connector on the rear. The output can be varied from 0 to 300V with 0.1V programming resolution and 0A to 6A current. The output frequency can also be adjusted from 45Hz to 500Hz with start and stop phase angle from 0 to 360 degrees. The bright VFD display shows Vrms, Irms, Ipeak, frequency, power factor (PF), apparent power, true power and elapsed output time. The AC sources provide a power line disturbance simulator, list mode and sweep mode for simulation of common power grid faults and disturbances.

A built-in dimmer function is 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.
