Custom Power Amplifiers
VT3 High voltage amplifier for
driving piezo stack
The VT3 model shown below is custom made to drive piezo
stacks of 40uF with 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 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.
Monitor outputs for output current and output voltage.

Inside view of the VT3:

Dimensions of the VT3 is 17"wide, 3.5" high and 12" deep.
Rack mount adapter available.
We can also make similar amplifiers for lower/higher voltage and
current.
