E-482.00: Operating limits (open loop) with various piezo loads, capacitance values in µF

PICA high-performance piezo amplifier

For dynamic continuous operation of PICA piezo actuators with high electrical capacitance. Analog control. Output voltage to 1050 V, bipolar can be set. 6 A peak current, 2 A continuous current.

Energy saving of up to 80 percent due to switched amplifier principle

Switching amplifier with pulse width modulation (PWM) of the piezo output voltage. When the piezo actuator is discharged, a circuitry for energy recovery stores part of the returning energy in a capacitor and makes it reusable for the next charging cycle. The amplifier runs cooler and provides better stability.

Application fields
