General description
The Falco Systems WMA-280 is an ultra-low noise, high-
voltage linear laboratory
applications. Its extreme voltage precision (2mV output
offset voltage), ultra-low output noise (300µV
voltage range (-150 to +150V) make it an excellent choice
for measurements where high precision is important. The
bandwidth is DC - 100kHz. It can be used for precise
positioning of MEMS devices (micromachines), with EO-
modulators, PZT (piezo) driver positioning systems, beam
steering components, ultrasonics, and many more.
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 20x ±0.1% (fixed). A fast current limit
of ±300mA (typical) and a fast short-circuit protection
make this amplifier suitable for both the normal daily

Safety
- This product is able to produce over 150V 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-280 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-280 from the mains power
before cleaning.
