PowerDrive Multi-channel drive systems
Modular platform enabling between 4 and 32 channels of waveform synthesis and amplification targeted at high power applications.
Overview
The Precision Acoustics PowerDrive system is a modular platform enabling between 4 and 32 channels of waveform synthesis and amplification targeted at high power applications, which is scalable and configurable with up to 8 stacked units utilising a rack mountable design to provide scalable performance to suit different needs.
With up to 20 W electrical power per channel available for indefinite continuous wave (CW), pulsed, or arbitrary waveform capability, the driver offers a robust solution for use with high-power transducers and arrays.
All channels are individually controllable via PC and synchronised for accurate phase control to < 0.03 λ precision over the whole 250 kHz to 20 MHz bandwidth, allowing use as a phased array controller for beam steering and focusing.

Product
The Precision Acoustics PowerDrive System provides a modular approach to controlling high-power transducer arrays.
Supplied as a 32-channel control system linked to individual blocks of 4-channel signal synthesis and amplification, the driver can be configured in 4, 8, 12… 32-channel options for the ultimate choice in modularity.
Capable of supplying a continuous or pulsed sinusoidal drive or an arbitrary waveform input, the multi-channel driver is software-controlled. Once connected to a PC, waveform and timing commands can be sent through the Array-Drive software supplied.
High-frequency digital clock signals from the control box allow precise timing and synchronization of the waveforms supplied to each channel, allowing signal phase to be accurately controlled to within fractions of a wavelength. [Figure 3]
With integrated thermal overload protection and all channels rated for simultaneous and continuous use at maximum power, the phased array driver is one of the most robust systems on the market for user-configurable multi-channel transducer driving and control.
Combining its modular approach and robust construction, the Precision Acoustics PowerDrive System is the ideal choice where flexibility and versatility are key for both research and development applications and for industrial users targeting reliability in a demanding environment
