Proposed Wiring Diagram for VF-90 Linear Amplifier

This document provides a wiring schematic intended for use with the VF-90 Linear Amplifier, specifically designed to drive piezoelectric loads.

Key Components and Connections

• Piezoelectric Load: The load device should be rated for voltage operation within either –30V to +150V or –30V to +200V.
• Power Supply: An AC/DC wall transformer, which is included with the VF-90 amplifier, supplies the necessary power.
• Input Signal: An analog input signal, such as from a function generator or D/A card, is used to drive the amplifier.
• Output: The amplifier provides power and ground connections to the piezoelectric (capacitive) load, for example, the FPA-500E FlexFrame PiezoActuator™.
• Voltage Supply: A +5.5V supply line is indicated as part of the wiring setup.

Critical Specifications and Recommendations

• The piezoelectric load must be compatible with the specified voltage limits to ensure safe and effective operation.
• Proper wiring according to the diagram is essential to maintain device integrity and performance.
• The use of the supplied AC/DC wall transformer is recommended to guarantee correct power delivery.

This wiring configuration ensures that the VF-90 amplifier can effectively drive piezoelectric actuators within the specified voltage ranges, maintaining device safety and performance.
