The E-481 four-quadrant high-voltage amplifier provides up to 2,000 W of dynamic output power with power consumption similar to a conventional 50-W piezo amplifier.
The output voltage range can be set by the user, up to 1100 V or ±550 V. Source/sink currents reach 2,000 mA and bandwidth is 5 kHz. These give the amp short response times and high slew rates, even with large capacitive piezoelectric loads.
