Rack Mountable Type High Voltage Amplifier
AMS/AMT series are a rack-mountable, fast response, high voltage operational amplifier that has been developed based on our many years of experience and expertise in high voltage. With a fast response up to 100 kHz, the AMS/AMT series can output high voltage in sine, triangle, sawtooth, and square waves proportional to the input waveform.
We have eight models with output voltage ranging from ±0.6 kV to ±10 kV, which are all solid-state.

Tech Notes
Capacitive Load
When a capacitive load is more than 100 pF (including a stray capacitance of output wire), the resonance in the output may occur. In that case, install 100 Ω (at 0.1 μF) to 1000 Ω (at 1000 pF) of high-voltage resistance in the output in series. Please note that the frequency band is limited when using an amplifier with a capacitive load, as shown in the formula on the right.
In addition, when an amplifier is used for a corona discharge, a current higher than its rating will flow, and it will affect the amplifier badly. In this case, as well as when using an amplifier with a capacitive load, please install the output resistance and limit the current.
* Please avoid continuous input of the high-frequency signal, which reduces the output frequency of an amplifier. An amplifier will break because of an increase in internal loss.
