E-619 High-Power Amplifier for Piezo Actuators
Modular System for Continuous Dynamic Applications
High-power amplifier for piezo actuators
High peak current, >5 A continuous current. High bandwidth for high dynamics. Suitable for PICMA® piezo actuators with special electrodes. Output voltage -30 to 130 V. Analog control. Evaluation of temperature sensor protects the piezo actuator against overheating

Optional servo controller upgrade
Optional control module for nanopositioning systems with integrated position sensors (SGS, capacitive). Optional interface module with wave generator, data recorder, digital interfaces (TCP/IP, USB, RS-232, SPI). Optional driver set for use with D/A converter boards from National Instruments and NI LabVIEW software

High degree of efficiency
Class-D switched amplifier with capacitor for energy recovery. Low influence of the application thanks to reduced heat dissipation

Application fields
Mechanical engineering: High dynamics placement, vibration absorber, noncircular grinding, valve control, materials testing, test equipment
High dynamics tip/tilt mirror applications
