E-481 PICA Piezo High-Power Amplifier/Controller
2000 W and high efficiency due to energy recovery
- Peak power 2000 W
- Integrated energy recovery
- Output voltage 0 to ±1100 V or bipolar
- Overheat protection for piezo actuators with temperature sensor
- 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 1100 V, bipolar can be set.
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.
