Generators TLT-1200 and TLT-1400 are an instruments for geophysical prospecting by means IP, Resistivity and Excitation-at-the-mass methods.These generators produce alternate polarity impulses to transmit them into grounded electrical supply line АВ. The current forms in the line АВ alternate polarity impulses with pauses between them (mode RPI-2) or without pauses (mode RPI-1). A value of the current can be automatically stabilized.Generators provide these conditions when the total resistance of the supply line AB (consisting of the resistance wire and grounding resistances lines A and B) in the range 25 - 1000 Om.

Commutation mode current and adaptation to changing load resistance: automatic.

The current in the line AB is reflected in the digital display. Operating current values from 150 to 2500 mA. The current value can be stabilized.

Electric generators have full protection on the output (short circuit, open circuit) and have the opportunity to work at any load (capacitance, inductance, resistance, in any combination).
