The TXM-22 is a highly efficient multi-purpose geophysical power source. It is designed for use in connection with the TXB-07 controller unit. The TXM-22 and TXB-07 form a powerful and flexible transmitter for geophysical applications such as Controlled Source Audio Magnetotellurics (CSAMT), Controlled Source Electro magnetics (CSEM) or Long Offset Transient Electromagnetics (LOTEM).

It can be operated in a wide frequency range between 0.001 Hz and 8,192 Hz. The output current is adjustable up to a maximum of +/-40A. The nominal output voltage is +/-560V.

The TXM-22 is powered by a 50/60Hz, 3-phase, 400V generator. In order to unleash the full capabilities of the system, a generator of min. 40 kVA should be used.
