BK Precision’s 9805 Power Supply’s maximum output of 1500 VA can be varied from 0 to 300 V with a programming resolution of o.1 V. The output frequency can be altered from 45 Hz to 500 Hz with a start and stop phase angle from 0 to 360 degrees.
BK Precision has equipped with 9805 with features such a power line disturbance (PLD) simulator and the ability to imitate common power grid disturbances and faults with the sweep mode. The available built-in dimmer function is ideal for testing LEDs and motors. Designed with efficiency in mind, the bright VFD display shows elapsed output time, Irms, Vrms, Ipeak, frequency, power factor (PF), true power and apparent power.

* 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.
