A-310
High Voltage, High power Amplifier/ Piezo Driver
The A-310 piezo Driver/Piezo Amplifier is a high Voltage, fast
Piezo Driver / Linear Amplifier for high power applications.
It was especially designed as a Linear Amplifier / Driver for high capacitance PIEZO Electric
Actuators (also known as "Piezo Amplifier"), stacks,piezo sheets, bimorph elements
and other devices.
The Piezo Driver / Piezo Amplifier is based on a high voltage, high frequency
and high current MOSFET amplifier which is capable of driving up to ±100V
(200V ptp) at ±2.5A at frequencies from DC to 250 kHz.
The A-310 amplifier is available in 2 configurations:
1. Single amplifier +/-100V output, +/-2.5A output current,DC- 250KHz. Frequency Bandwidth.
2. Dual amplifier - 2 independent amplifiers with independent inputs and outputs., +/-100V
outputs, +/-1.2A output current capability, DC-250 KHz. Frequency bandwidth.
By connecting 2 amplifiers in inverting, differential connection to a floating load, up to +/-200V @ +/-1.2A can be delivered to the load (240W peak or 120W RMS).
The amplifier section is very stable and has a very low
electrical noise - Compare Our Specifications!
This High speed Amplifier / Driver can be used for Various applications

The amplifier/s are housed in a standard 19" rack enclosure, 4U height.
Weight: 24 Kg.
Applications:
2 amplifiers can be connected in series or in parallel
in order to double the Output Voltage or Output Current.
Series connection (+/- 400V into a floating load = 800V ptp).
Calulating the estimated current needed to drive your load:
| In order to purchase the right amplifier to drive your load, you must calulate the peak current needed. | |||
| For Capacitive load: | |||
|
Ipeak(A) = 2 π F C Vpeak (for a Sine Wave) Ipeak(A) = 4 F C Vpeak (for a triangular wave) Ipeak(A) = C dV / dt (for a square wave or sharp rise time) |
||
| F=Maximum frequency (Hz.) π=3.1415927 |
C=Capacitance in Farads Vpeak=Maximum Voltage you need to drive your Load. |
||
| For Resistive Load: | |||
| I = Vpeak/R | |||
| where R is the resistance of your load in Ohms. | |||
The current, Voltage and Frequency must be less or equal to the amplifier's specifications.
This amplifier is NOT SUITABLE for driving pure inductive loads
(i.e. speakers, solenoides, electromagnets etc.)
You must connect your load with thick wires to minimize inductance (like speaker wires). Coaxial cable is not recommended for cables over 2m (6.5 Ft.) because the capacitance of the cable (15-50 pF/Ft) will load your amplifier at high frequencies.
| Example: The active impedance of a capacitive load is given by the equation: Z=1/(2*Pi*F*C) where Pi=3.1415, C in Farads, F in Hz.The user must check that under the peak operation Voltage, at maximum frequency, the current will not exceed 2500mA (2.5A). Example: Output Voltage is +/-100V, Maximum Frequency=20KHz. Load is 100nF. Z=1/(2*3.1415*20,000*100EE-9) =79.6 Ohms. 100[V]/80[Ohm] =1250[mA] ===>The single channel amplifier will drive that load at an amplitude of 100V (200V ptp). For the dual channel amplifier, this load is marginal because the current capacity is only 1200mA. |
