Battery Powered TDEM (TEM) Current Source

The AT-3000 transmitter is lightweight, portable, battery powered geophysical current source specialized for Time Domain EM (TDEM, TEM) and Time Domain Induced Polarization (TDIP) methods with various field arrays (gradient, dipole-dipole, pole-dipole, etc.) and is intended for solving wide range of mining exploration, prospecting and mapping tasks in 20 – 1000m depth interval.

AT-3000 is powered by 12V-150V DC external supply or BAT-60 battery pack, has 3kW/ 40A maximum output (square wave, 50% duty cycle), very fast output turn-off times and current waveform recording function with AT-Tx10 controller. Output loops have flexible configuration and are assembled with quick-mate insulated connectors which allow robust construction of various size Tx loops. Recommended Tx loop sizes – 50 x 50m, 100 x 100m, 200 x 200m, 400 x 400m. Custom sizes are available upon request.

AT-3000 is easy to use Stand-Alone TDEM/TDIP transmitter which does not require any other external devices (PC, tablets, etc.) for field operation. AT-3000 set includes AT-Tx10 controller with intuitive GUI touchscreen user interface, manual and automatic operation modes, real-time parameters monitoring, operator notifications and fault detection, numerous build-in safety features (reverse polarity, line break detection, emergency stop, etc.), GPS and cable synchronization options and fully realizes resolution capabilities of TDEM (TEM) and TDIP methods in the field.
