High-power amplifier for low-voltage piezo actuators
Peak power up to 280 W, average output power up to 100 W. Output and absorption of peak current up to 2000 mA. Dynamic operation of piezo actuators with high capacity at a bandwidth up to the kilohertz range.
High performance with heavy loads
An analog input voltage is amplified in the E-617 amplifier by a factor of 10 and provides precision control of piezo actuators and piezo positioning systems. This analog mode is ideal for applications where fast response times are essential at maximum bandwidth. The specification or position feedback in absolute values is either not significant or is done by external position sensors.
Energy recovery
The efficient switching principle reduces the power consumption and heat dissipation considerably, especially in dynamic applications. In this way, the energy is coupled into the piezo with low loss via pulse width modulation (PWM). The energy generated by the discharging piezo is recovered and made available for the next charge. A unipolar supply voltage between 23 to 26 V DC is sufficient for operation.
Application fields
Industry, automation. High dynamics scanning or switching applications.
