AAE Energy Sources, CSP-SNv 1250

High-Speed Seismic Energy Source for Ultra-High Resolution (UHR) Surveys

Product Overview The Applied Acoustic Engineering (AAE) CSP-SNv 1250 is a high-performance seismic power supply engineered specifically for demanding Ultra-High Resolution (UHR) geophysical surveys. Building on the proven architecture of the CSP-Nv series, the "SNv" variant is distinguished by its significantly higher charging rate—4000 Joules per second—enabling the extremely fast repetition rates (up to 3.3 shots per second at 1000J) required for high-density data acquisition.

It is the primary power source for the dual-deck Dura-Spark UHD 400+400, providing the specialized Flip-Flop and Fire-Delay modes necessary to manage complex sound signatures and minimize bubble collapse.

Why Choose the CSP-SNv 1250?

• Industry-Leading Charge Rate: With a peak charge rate of 4000 J/s, the SNv 1250 is double the speed of the standard CSP-Nv 1200. This allows for a shot interval of ≤1m even at high vessel speeds, ensuring no gaps in critical sub-bottom data.
• Advanced Firing Modes: Specifically designed to control dual-source arrays.
  • Flip-Flop Mode: Fires two separate sparker decks alternately to increase horizontal resolution.
  • Fire-Delay Mode: Staggers the firing of two decks to "bubble form" the acoustic signature, creating a cleaner, more stable pulse.
• AVIP Technology: Features Automatic Variable Input Power, a "soft start" circuitry that reduces the initial demand on generators, allowing for the use of smaller, more fuel-efficient power sources on small survey launches.
• Microprocessor Precision: Full digital control allows the operator to tune the voltage and energy output in precise increments, matching the power to the specific sub-bottom conditions and sound source (Sparker vs. Boomer).
• Rugged Reliability: Housed in a shock-mounted, IP-rated transit case with comprehensive safety interlocks, including high-speed dump resistors and over-voltage shutdown.
