The Applied Acoustic CSP-P Seismic Energy Source is the lightest and most compact capacitor discharge 4kV power supply available from GoSubsea. This unit contains Variable Input Power Circuitry (AVIP) enabling the CSP-P to operate from the smallest of Generators. No internal adjustments are required as all controls are on the front panel. Use with surface tow or sub tow boomer sub bottom profiling systems. The unit is supplied within a hard transit case and a high voltage junction box. CSP-P now incorporates dual-voltage technology that allows the operator to tune the sound source to a particular application for improved data quality.
