Power supplies Jack ensure the operation of electrosparking and electrodynamic sources used in geophysical surveys in boreholes by methods of crosshole seismic testing (CST), vertical seismic profiling (VSP), vertical seismoacoustic profiling (VSaP) and others.


Jack design deploys a reliable thyristor key, that enables obtaining a really short high-voltage electric pulse. The power supply is operated from ас system with 110 / 220 V voltage.


In Jack-500 and Jack-1200 models, pulse chargers provide an average charge rate of 500 J/s. Jack‑2500HP version is equipped with a fast charger that is capable to regulate the charging speed (500 / 1000 / 1500 J/s). Thus, all Jack power supplies allow operation with compact portable generators (with power of 0,8 kW and more).


Jack power supplies allow one to work with three triggering modes:

  • triggering from an external device (seismic station, synchronization system, etc.)

  • a series with a given number of pulses and a period of their repetition

  • infinite series of pulses with a given period.


Power supplies Jack can be equipped with a portable remote control unit JackPad.


Compact dimensions, impact-resistant leakproof Pelicase casing, light weight, well-conceived and intuitive user interface, remote control unit, allow to consider Jack power supplies as the most modern and truly mobile devices among all the analogues available on the market.


The standard set of Jack power supply consists of:

  • Jack Unit

  • Sync connector (2 pc.)

  • Power cable

  • Universal switching module for connecting the source

  • Documentation Kit.


In addition to Jack power supplies the following items can be purchased:


As may be agreed, it is possible to manufacture a power supply and a source of the required power and configuration. For the correct preparation of technical design specification, please contact us using any method indicated on the website.


For performance of high-resolution marine seismic operations, the specialized power supplies MultiJack are available.
