Description
The single-channel high voltage amplifier HA51U-3B2 with bipolar output voltage is designed to drive
capacitive and ohmic-capacitive loads.
The amplifier is characterized by high speed, good stability and low noise. Piezo elements,
electroactive polymers, electrorheological fluids, electrostatic deflecting electrodes and many other
loads can be driven by this amplifier easily.
Output voltages of -3000V to +3000V at load currents of up to ±2.5mA and >5mA
P
are provided. The
signal gain is 300, the input voltage range is -10V…+10V.
The output voltage can be monitored by a high-speed voltage monitor; a current monitor provides a
representation of the output current.
The amplifier’s output is protected against overload, short circuit, overtemperature, transient
overvoltage and high voltage flashover. The LEDs on the front panel indicate operation and error
statuses.
An isolated USB interface is provided, allowing the user to control the amplifier via a simple command
interface (output voltage setting, voltage and current back reading, readout of temperatures and other
operating parameters, amplifier configuration, I/O lines setting and readout, ...).
Alternatively, the internal microcontroller can be utilized to allow the user to run his own application
programs. For example, to generate simple, arbitrary waveforms. It is also possible to run more
complex applications. For this purpose, additional free I/O lines and a separate analog input are
provided.
The internal microcontroller can be programmed via the free Arduino IDE. The entire application
software of the amplifier is available as open source.
The HA51U is housed in a sturdy aluminium case. It can be operated as a tabletop unit or be built in a
device housing.
