The BK Precision 9803 has a supplies a maximum output of 750 V that can be varied from 0 to 300 V with a 0.1 V programming resolution. Adjustments to the output frequency can be made from 45 Hz to 500 Hz with a start and stop phase angle from 0 to 360 degrees.
The 9803 is not just a power supply, but acts as a measurement tool as well. Users can analyze apparent power, power factor (PF), true power, Ipeak, elapsed output time, Vrms, frequency and Irms on the illuminated VFD display. The sweep mode is vital for applications that need to simulate common power grid faults and disturbances. Even applications that test motors and LEDs are suited with the available built-in dimmer function.

* The current range switches from low to mid range or mid to high range when Ipeak > 300
% of the present range.
When Ipeak is <80 % of the high range, the current range switches from high to mid range.
When Ipeak is <20 % of the mid range, the current range switches from mid to low range.
