PI News: E-617 High-Power Piezo Driver & Amplifier OEM Modules with Energy Recovery for High-Dynamics 24/7 Operation ; E617

E-617 OEM Module: High-Power Piezo Driver / Voltage Amplifier with Energy Recovery for High-Dynamics 24/7 Operation

  • Very Low Power Consumption due to Energy Recovery Principle
  • Extremely High Power Compared to the Compact Design: to 280 Watts
  • High Source & Sink Currents to 2 Amps
  • Output voltage -30 to +135 Volts
  • OEM Module and Top-Hat-Rail Versions
  • Amplifier bandwidth, small signal 3.5 kHz
  • Short-circuit-proof
  • Two Versions: Open Card & Enclosed for Top-hat-Rail Mounting in Switching Cabinets

Energy Recovery Operating Principle
The E-617 piezo driver modules provide significantly higher power than conventinal piezo amplifiers of similar size. The working principle of the E-617 series is ideally suited for high-dynamics scanning and switching applications.

The innovative, efficient circuitry reduces power consumption and heat dissipation, especially in dynamic applications. Charge is transferred to the piezo actuator using low-loss PWM techniques. When the actuator is discharged, the energy not consumed is fed through the energy recovery circuitry for reuse in the next charging cycle.

PI has introduced piezo amplifiers with energy recovery several years ago. An even more powerful high voltage amplifier (2000 Watts of peak power) is available as model number E-481.

High Performance with High Capacitive Loads
The E-617 amplifiers provide precision control of piezo actuators and positioning systems in open-loop operation with an analog control voltage amplified by the factor 12. Such analog operation is ideal for applications where fast response and very high resolution with maximum bandwidth are essential, but where commanding and reading the target position absolutely is either not important or carried out by external position sensors.
