DJF-10A Big-Power IP& Resistivity Transmitter
 
DJF-10A induced polarization transmitter, an induced polarization sending system composed of DJF-10A main set and DZ-10A commutation supply, is an automatic power supply device matched with DWJ-3B microcomputer induced polarization instrument.
 
Feature:

• Duty ratio of 1:1 with periods of 4″、8″、16″、32″、64″.
•  An external controller where the power-on time and period is controlled by the DWJ-3B, which especially applies to IP Groundwater Prospecting, IP sounding, IP in near field sourer, IP oil finding, even in strong interference environment.
• The high voltage power supply can be provided by the DC from DZ-10A(dummy load equipped with balancing generator), or by dry cell and storage cell in case of low power, which indicates a strong adaptability.
• The main circuit works steadily and reliably by reason that it has adopted silicon controlled rectifier Commutation Bridge and DC switch without mechanic contacts.
