DESCRIPTION

The VT3 model shown below is custom made to drive piezo stacks of up to 40uF with up to 200V square waves. This amplifier can drive a 40uF load with 200V square wave at 120Hz. Rise/fall time is 400uS for a 200V step and 40uF load (2 V/uS). The max. charging current is 20A. Output is protected for short circuits, so if the stack shorts out the amplifier just shuts down. Amplifier also protected agains overtemperature.
