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.

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 LE 1000/035 is an analog amplifier with 350 mA output current, specifically designed for use with standard hpower piezo stack and ring actuators that need to work at high frequencies.

The power amplifier LE 150/100 EBW has an idle bandwidth of 70,000 Hz and 1 A output current. This amplifier is specially designed to be used with hpower actuators at highest working frequencies. The high bandwidth, high current and low noise features make it perfect for high-frequency vibration excitation testing and modal analysis.

The HVP 1000/200 power amplifier is designed to drive hpower actuators with a high charging currents for pulse operation in “on-off” square-wave mode. In this operation a current of 200 amps flows for a short time. The voltage increases in the hpower actuator a few μs. The rise time and the discharge time can be modified based on specific requirements. Applications for this system include model analysis, vibration control, material testing and mechanical engineering.
