About this manual
This user manual is an integral part of the Falco Systems
WMA-320 amplifier product. Please read it carefully and
pay attention to the recommendations and the instructions
for safe use.
General description
The Falco Systems WMA-320 is a high speed, high-
voltage linear laboratory amplifier for demanding
applications. Its wide bandwidth and large voltage range
make it an excellent choice for use with MEMS devices,
EO-modulators, PZT positioning systems, beam steering,
ultrasonics, dielectric studies, and many others.
Through the extensive use of computer modelling and
state-of-the-art design concepts, this amplifier can be used
in many applications, including those where conventional
amplifiers are difficult to apply. It is designed to be
absolutely stable and free of spurious signals with any
capacitive load.
The amplification is 50x (fixed). With a range of –100V to
+100V, a 5MHz @ - 3dB large signal bandwidth and a
typical slew rate of 1300V/
µ
s, this amplifier will enable
many measurements in different applications. Its
frequency response is essentially flat up to 2MHz.
A fast current limit of ±300mA (typical) and a fast short-
circuit protection make this amplifier suitable for both the
normal daily laboratory use (and abuse), and automated
measurement systems.
Safety
- This product is able to produce over 100V at
more than 300mA at its output, which is a
dangerously high level (risk of electric shock). Safety
measures should be taken accordingly.
- Only use this appliance with a mains connection with
protective earth
- The internal circuitry of the amplifier operates at high
voltage. Only qualified personnel from Falco Systems
should service this amplifier.
- When the amplifier is turned on or off, a short voltage
spike may appear at the output which may damage
circuitry already connected to it.
- Replace fuses with 250V 630mA 5x20mm slow blow
rated fuses only.
- The Falco Systems WMA-320 is only suitable for indoor
use in a class II environment (domestic, light industrial).
- This product should only be cleaned with a soft, slightly
moist cloth. Unplug the WMA-320 from the mains power
before cleaning.
