E-481 PICA™ Piezo High-Power Amplifier/Controller, 2000 W and Energy Recovery for High Efficiency

 
  • Peak Power 2000 W
  • Energy Recovery
  • Output Voltage 0 to ±1000 V or Bipolar

  • Computer Interface & Display Modules

The E-481 high-power piezo amplifier/controller is specifically designed for dynamic operation of high-capacitance PICA™ PZT actuators.

The E-481 is based on a novel design combining pulse width modulation and energy recovery. Instead of dissipating the reactive power in heat sinks, this energy is temporarily stored in inductive elements. Only the active power used by the piezo actuator has to be delivered. The energy not used by the actuator is returned to the amplifier and reused as supply voltage via a step-up transforming process. A peak sink and source current of up to 2000 mA is possible.
