3 Description

The single-channel high voltage amplifiers HA2B5-S / HA3B3-S with bipolar output voltage are
designed to drive capacitive and resistive-capacitive loads.
The amplifiers are 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.
For HA2B5-S output voltages of -2000V to +2000V at load currents of up to ±5mA and >7mA
provided. The signal gain is 200, the input voltage range is -10V...+10V.
For HA3B3-S output voltages of -3000V to +3000V at load currents of up to ±3mA and >5mA
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.
HA2B5-S and HA3B3-S are 3U plug-in cards intended to be mounted in a suitable subrack.
The deviced incorporate the high voltage amplifier itself, high voltage sources for the output stage,
measuring functions as well as monitoring and protective functions.
The amplifier's output is protected against overload, short circuit, overtemperature, transient
overvoltage and high voltage flashover. LEDs on the front panel indicate operation and error statuses.
The HAR42-4 is a tabletop subrack to accommodate up to 4 high voltage amplifier modules HA2B5-S
or HA3B3-S. Both models can be combined in a single subrack.
It features internal power supplies, cooling fans, a common Interlock input for all channels and a HV
OFF button. Customized and full custom models are available on request.
