To accommodate industry demands for power output, Applied Acoustics manufactures a range of CSP units that provide the energy to the sound source, a Boomer or Sparker, deployed at sea. Each compact design CSP energy source converts mains voltage to high voltage to energise the sound source and conforms to EU specifications for electromagnetic compatibility.

The CSP-Nv differs from the previous range of CSPs in that it supplies a negative-going pulse and can therefore be used with various negative pulse sparker systems. They incorporate microprocessor control and configuration for greater flexibility band reliability whilst retaining a fail-safe logic design. It has an intuitive user interface with LCD display and LED indicators to provide enhanced operator feedback.

Programmable voltage technology allows operator tuning to suit the application with all settings externally selectable.

The CSP-Nv is the driving force behind the negative pulse Dura-Spark range but is also suitable for use with the S-Boom system and single plate boomer systems.
