Product introduction



Wisman's  AMU series is a high-voltage power amplifier for industrial and research applications. The unique 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.
