The choice of a 1000V-7A Amplifier / Piezo Amplifier :
1000V Amplifiers are devided in two choices : Linear (LE) or Recharging (RCV). Of course both have their advantages and disadvantages :
The linear 1000V -1A Amplifier type needs semiconductors ,able to change the resistance to operate from 0 to 1000V under the full level of output-current , : so 1000V with 1A means a lot of (pulsed ) power (UxI), so this power has to get absorbed by ..heatsinks and fans , even with relatively low currents. The advantage of the linear 1000V Piezo Amplifier is a good low noise behaviour , also bandwith and phaselag can get adapted to smaller piezos.
The Recharging 1000V 7A Amplifier works in switched mode , this means much less powerloss (appr. n=10..20%).
So its possible to build rather big recharging 1000V Amplifiers in the same housing like a linear 1000V Amplifier
but 7 times bigger in current (linear Amplifiers 1A 1000V; recharging Amplifier 7A 1000V).
So the Recharging 1000V Piezo Amplifier is good to drive big piezos and capacitive loads in the range of 1 and 20uF , with a good bandwith for this range of load. The maximum
power is up to 10kW for a time reasonable limited (1...2 SEKONDS)
High Power Piezo Driver; HV Amplifier; 1000V -7A Amplifier, Recharging Amplifier:
This is a rare to find 1000V (500V,200V) recharging piezo amplifier at the competitors:
Piezo Driver for high power demands , optional with 1050+ and 200V- , or +/-500V.
I maxpeak >7A,Sinus peak continuously , not only for some milliseconds
Bandwith >1kHz .Charge Recovery : I-line consumption < 3A at full load.
Line voltage 240VAC , or 110VAC.
Other versions : 500V/15A.
Adaption to the application is necessary and possible to reduce noise and power if needed.
Linear Amplifier 1000V -1A; HV Amplifier ; Piezo Driver HV ;Linear Piezo Amplifier Type PAV LE1 and PAV
For lower currents and voltages <1000V a linear piezo amplifier is a good choice to drive piezos.
New design 2017!!!:
Type PAV LE1:
Type PAV LE2:

- 100V- 4A ...>8kHz BW
- 1000V -1Ap; ...>8kHz BW.
- 300Vmax- 5Ap ...>8kHz BW
- the circuit works , perhaps adaption needed, till appr 30kHz
Shortage proofed , wide safe operating area (SOA)
no limitation of current versus time (reasonable limited)
good reliability , low noise, good thermal behaviour.
It is possible to adapt it to 200V , 500V and 800V piezos

Glow Discharge Driver ; HV- DC Generator ;
GD (Glow Discharge):
Glow discharge Generator 1200V DC 100mA , Interface , U-,I-Controll , Arc-detector,stable
This module drives a stable voltage into a glow discharge with an ignition voltage under 1200V.
If the conditions in the discharge changes , the current rises up to an external adjustable value , so its voltage- and
current- controlled .It works with 240V and 110V AC.
Application :spectral analysis of the glow discharge zone on the surface of conductive material.
This picture shows a glow discharge spectrum analyser (Swiss Product , 1980) , updated with SG1200, it replaces the old fashioned (but good) tube generator to assure future functionality to save this reliable equipment.
