200 / 400 V Amplifier
The aixACCT High Voltage DC-stable power amplifier is designed to provide precise
control of bi-polar output voltages. It is available as a 200 V or 400 V output
voltage. The 200 V version operates with an output voltage in the range of 0 to
±200 V DC or peak AC. The 400 V version operates in the range of 0 to ±400 V DC
or peak AC. Applications for the High-Voltage Amplifier include AC and DC biasing
for piezoelectric material characterization.
The High-Voltage Amplifier is configured as a noninverting amplifier with a fixed gain
of 40 V/V. Features include an all-solid-state design for a slew rate greater than
100 V/μs, a large signal bandwidth (-3dB) of DC to greater than 100 kHz. The
active output stage sinks or sources current into small reactive or resistive loads
throughout the output voltage range which is essential for achieving the accurate
output responses and high slew rates demanded by reactive loads.
The voltage monitor provides low-voltage output signals for monitoring purposes. A Digital
Enable feature provides a connection for a remote device to turn the high voltage on and off.
