Electrical Exploration transmitter VP-1000

Specifications

Under the load, the transmitter produces bipolar rectangular current pulses and is capable of operating in two modes:
- RPI-1 – rectangular current pulses without intervals (AC mode);
- RPI-2 - rectangular current pulses with intervals, having the same duration as the pulses.
The set values of constant current amplitudes under a load are: 0.01; 0.015; 0.02; 0.03; 0.05; 0.075; 0.1; 0.15; 0.2; 0.3; 0.4; 0.5; 0.6; 0.7; 0.8; 0.9; 1.,0; 1.1; 1.2; 1.3; 1.4; 1.5; 1.,6; 1.7; 1.8; 1.9; 2.0 A.
Current pulse amplitude assignment error – 2%, maximum.
Output voltage range – 50-800 V
Duration of output current pulses in RPI-2 mode: 1; 2; 4; 8; 16; 32; 64 s.
Frequencies of output current in RPI-1 mode: 19.6; 9.8; 4.88; 2.44; 1.22; 0.61; 0.3 Hz.
Maximum output current peak power – 1000 W.
Load resistance range within which constant-current regulation is performed – 25-80 kohms.
The transmitter is power supplied from the external AC source of 220 V, 50 Hz.
Weight - 10 kg.
