VF-90-30150 Piezo Amplifier Description DSM's VF-90 linear piezoelectric amplifier module provides functionality for driving piezoelectric (capacitive) loads in an extremely compact form factor. The single channel module is designed into National Instruments' CompactRIO format for use in a CompactRIO and CompactDAQ chassis or for use outside of the chassis environment. The VF-90 is powered by a 5.5V AC/DC adapter (included). Electrical connections for power, input signal, and output voltage are made through the module's screw terminals. The VF-90 features overcurrent, over-temperature, and short-circuit protection as well as protection against over/under voltage conditions on the power line. • Over-current protecƟon • Over-temperature protecƟon • Short-circuit protecƟon • ProtecƟon against over/under voltage conditions on the power line • RoHS compliant • FCC compliant • CE Compliant • NaƟonal Instruments' CompactRIO format (communication and power is external). • 5.5V AC/DC adapter included Output Voltage (V): Input Voltage Signal (V): Max Peak Current (mAp): Dimensions (in): Dimensions (mm): Operating Voltage (VDC): Bandwidth (kHz): Noise (mVrms): Gain (V/V): Recommended Min.

Do not allow the input signal to exceed the prescribed input voltage range, or damage to the piezo load can occur. (2) Under certain operating conditions, the VF- 90's power capabilities can exceed the maximum heat dissipation allowable by NI's CompactRIO and CompactDAQ specifications.
