The WMA-01 high voltage
amplifier: general description
The Falco Systems WMA-01 and WMA-
01LF are high voltage amplifiers that run
from an 24V DC power supply and can be
battery powered if required, e.g. for use in
a Faraday cage. Its internal high voltage
generator is inductor-free and hence does
not spread magnetic
sensitive experimental setups. Its large

modulators, piezo actuator positioning
systems, beam steering components, and
many more.
The
response has a -3dB corner frequency at
20kHz. The input impedance is 100kΩ and
the output 50kΩ.
The output noise of the WMA-01 is

applications where bandwidth is not an
issue, the dedicated WMA-01LF version is
available. This amplifier contains an output
low pass filter capacitor which reduces the
bandwidth to 50Hz, but makes the noise
drop to 0.1mVrms. This bandwidth-limited
amplifier is ideal for MEMS or piezo
