±500V to 6000Vpp, 15W – 20W, Programmable High Speed High Voltage Amplifiers
Programmierbare, schnelle Hochspannungsverstärker - HA51U
Programmierbare, schnelle Hochspannungsverstärker - HA51U

The HA51U series is a family of single channel, bipolar, unipolar and unsymmetrical high voltage amplifiers. They feature high speed, high precision and high stability as well as very low ripple and noise. They are designed to drive capacitive and resistive loads. High peak output current facilitates easy driving of capacitive loads.
Each amplifier of the HA51U series is equipped with voltage and current monitor outputs, a TTL-compatible INHIBIT input and further monitoring outputs. The output stage is fed by internal high voltage sources. The amplifier output is protected against overcurrent, short circuit, overvoltage, overtemperature and high voltage flashover. A safety interlock feature is provided to integrate the unit into a safety circuit.
An isolated USB interface is provided to control the amplifier by means of a simple command interface (setting of the output voltage, monitoring of output voltage, current, temperature and further operational parameters, configuring the amplifier). Alternatively, the internal microcontroller can be used to run the user's own application code. This can be simple arbitrary waveform generation or direct control of the output voltage via USB.
More complex applications are possible too. General Purpose I/O lines and a separate analog input are provided to connect additional components to the amplifier that can be controlled.
Programming of the controller is possible e.g. by means of the free Arduino IDE.
The amplifiers are available in a robust modular metal case or as 3U cassette versions. The modular units can be used as a table-top device or built into an appliance.
Up to four 3U cassette version units can be plugged into a 19" subrack. Subracks with internal power supplies, cooling fans and a fast-off button are available on request. Customized and full custom models are available on request.

-200V to +600V, ±10mA, 64 Channel Precision High Voltage Amplifier
64-Kanal Präzisions-Hochspannungsverstärker HAR8x8A

Rack mountable Precision High Voltage Amplifier in a 19" 7U high subrack. Sixty-four independent amplifier channels provide output voltages in the range of -200V and +600V at output currents of ±10mAp. The output voltage of each channel can be controlled by means of a setpoint input. Differential amplifiers on the setpoint inputs prevent any ground loops and provide excellent noise suppression. Each channel is equipped with an output voltage monitor.
The unit consists of 8 amplifier modules with 8 channels each. The amplifier channels feature high precision, high stability as well as very low ripple and noise. The amplifier outputs are protected against overload, short circuit and over-temperature.
The amplifier is optimized for driving multi-channel capacitive or resistive-capacitive loads. It can easily drive electroactive polymer actuators, piezo elements, electrorheological fluids, ion beam deflectors and many other loads.
The high voltage outputs are protected against overload, short circuit and overvoltage. Operating states and fault conditions are displayed on the front panels.
A safety interlock circuit is provided to integrate the unit into an emergency shutdown circuit.
The standard output voltage range is -200V to +600V. Versions with output voltage ranges of ±500V or 0 to +1000V are available. Output voltage ranges can be installed mixed in a single mainframe in groups of eight.
Customized and full custom models are available on request.

9400 Amplifier

High voltage signal amplifiers are a must in applications requiring both complex signals as well as high voltage throughput. Such a combination is rare in high performance instrumentation and therefore external amplification devices must be used to achieve this task. The Tabor line of wideband amplifiers was designed to operate in conjunction with its series of waveform generators thus providing the ultimate solution for high-voltage, wideband applications.
