DT Series, 4-Wire DC Current Transducer

Product Description
NK Technologies DT Series of DC Current Transducers combine a Hall effect sensor and signal conditioner into a single package for use in DC current applications up to 400 A. The DT Series DC Current Transducers unipolar and bipolar models have jumper-selectable current input ranges and industry standard 0–20 mA, 4–20 mA, 0–5 VDC or 0–10 VDC outputs. DT transducers are available in a split-core case.
DC Current Transducer Applications
  • Battery Banks
    • Monitors load current.
    • Monitors charging current.
    • Verifies operation.
  • Transportation
    • Measures traction power or auxiliary loads.
  • Welding Processes
    • Measures the current used while welding.
    • Log processing time and number of operations.
  • Photovoltaic Panels
    • Monitor panel or string current output.
    • Monitor combiner box output.


Three Jumper-selectable Ranges
  • Reduces set-up time.
  • Reduces inventory.
  • Eliminates zero and span pots.
  • Output is magnetically isolated from the input for safety.
  • Eliminates insertion loss (voltage drop).
Internal Power Regulation
  • Works well, even with unregulated power.
  • Cuts installation cost.
Split-core Design/Built-in Mounting Brackets
  • Makes installation a snap.
