| NK Technologies - DT Series, DC Current Transducers |
| |
| DT Series Current Transducers combine a Hall effect sensor and signal conditioner into a single package for use in DC current applications up to 400A. The DT Series has jumper selectable current input ranges and industry standard 0–20mA, 4–20mA, 0–5VDC or 0–10VDC outputs. Available in solidor split-core enclosures. |

Battery Banks
- Monitors load current.
- Monitors charging current.
- Verifies operation.
|
Transportation
Measures traction power or auxiliary loads. |
Electric Heating Elements
- Monitors heater loads.
- Faster response than temperature
sensors.
|
|
- Three Jumper Selectable Ranges
- Reduces inventory.
- Eliminates zero and span pots.
- Isolation
- 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.
