HA51U - Programmable High Speed High Voltage Amplifiers

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.
The HAR-51-4M is a 19"/3U subrack for up to 4 high voltage amplifier cassette modules HA51...-3.
It features internal power supplies, cooling fans, a common Interlock input for all channels and an HV OFF button.
