E-482 PICA High-Performance Piezo Amplifier / Servo Controller
High Energy Efficiency due to Energy Recovery
- Peak current 6 A
- Output voltage to 1050 V
- Integrated energy recovery
- Temperature sensor protects piezo actuator from overheating
- Position control (optional)
- Interface / display modules (optional)
PICA high-performance piezo amplifier
19-inch benchtop device 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 % 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.
