Power amplifier provides 6A peak for high-voltage piezo actuators

18 December 2012

PI's (Physik Instrumente's) new E-482 high-power piezo amplifier/controller provides a 6A peak current at 1,050V in a 19in bench-top unit. The amplifier is suitable for the operation of piezo actuators with high electrical capacitance, such as the PICA piezo actuator series P-225 and P-235.

This class D switching amplifier modulates the pulse width of the control signal and thus controls the piezo output voltage.

When the piezo actuator is discharged, a patented circuitry for energy recovery stores the returning energy in a capacitor and makes it reusable for the next charging cycle. Thus, the E-482 achieves high efficiency with peak currents of up to 6A and average currents of up to 2A. 

The power amplifier will also accept the E-509 sensor-/servo-controller module for closed-loop operation.
