hpower actuators combine fast response times in µs, superior kHz dynamics, high force generation in the range of tens of kN, and nanometer precision. The HPA 1000/10 is a switching amplifier specifically designed for use with standard hpower piezo stack and ring actuators or other capacitance loads with at least 1 µF capacitance. With an output power of <4 kW and its energy recovery design, the HPA 1000/10 amplifier provides high performance in dynamic applications such as modal analysis, vibration control and material testing.
