description of the voltage amplifier
7.1. common introduction
The voltage amplifier system ENT / ENV was specifically developed for
positioning tasks.
The voltage amplifier system ENV was developed for one or more dimensional
positioning requirements in optics, laser physics, microbiology, machining, etc..
With an output noise lower than 0.3mV, it is well suited for positioning in the sub-
nm range. This amplifier can also be manufactured for the 19” casing.
The system consists of various modules, which can combined. This allows you to
customise your set of electronics. A complete system consists of at least one
main supply ENT and one amplifier module ENV, wired in the casing.
It is possible to operate the amplifier module remotely by using the MOD
(modulation input) socket. There is safety wiring integrated, which is helpful in
avoiding voltage peaks during switching. Another safety guard avoids high
voltages to the piezo actuator to prevent the damaging of the piezo-element.
The digital EDA board is available with RS232 and/or IEEE488 interface line.
Manual control can be done by using a 10-turn potentiometer for each channel.
The ENV voltage amplifiers have an excellent low noise behavior which allows
fine positioning tasks in the sub-nm range.
Please note: when using a module
“EDA” to remote the amplifier, the modulation
input and the offset potentiometer will be disabled during the remote mode is
active.
