Product introduction



Wismans high voltage amplifier AMY40R600, output voltage ±40kV, output current 15mA, type is a high voltage power amplifier, used in industrial and research applications. All solid-state high voltage insulation design can achieve high conversion rate, wide bandwidth and low noise operation. The four-quadrant active output sinks or outputs current to reactive or resistive loads within the entire output voltage range. This type of output is essential for achieving accurate output response and the high slew rate required for various loads, such as high capacitive or reactive loads. The amplifier is a non-inverting amplifier.
