About this manual
This user manual is an integral part of the
Falco Systems WMA-IB-LN ultra-low noise
phase inverter - buffer product. Please
read it carefully and pay attention to the
recommendations and instructions for safe
use.
Operation of the phase inverter
The WMA-IB-LN is an ultra-low noise
phase inverter – buffer designed to drive
one or two Falco Systems WMA-200 high
voltage amplifiers. It can be used:
To drive two amplifiers in bridge mode by
using both the buffered output and the
inverting output, or
As a buffer between a signal source
and the amplifier
The BNC and differential input can be
used with signals up to ±10V input voltage.
The signal on the BNC connector is
converted to a differential signal to drive
the
high
voltage
amplifier(s).
The
differential outputs have a low impedance
and are short-circuit protected.
The WMA-IB-LN ships with a customized
Mean Well GS25B28-P1J power supply.
The power supply connector, 315mAT
fuse and on-off switch are on the rear
panel of the WMA-IB-LN enclosure. A blue
led indicates that the WMA-IB-LN is on.
The outputs are on the left of the front
panel to accommodate neat cabling to
high voltage amplifiers that typically have
their inputs on the left side too.
Bridge mode
The WMA-IB-LN can be used to double
the maximum output voltage driving a
load, such as a piezo actuator, EO
(electro-optical) modulator, or MEMS
(electromechanical
systems)
device,
among many others. This is achieved by
driving two high voltage amplifiers both
