NK Technologies AT Series
|
Features:
- Accurate
Factory matched and calibrated single piece transducer is more accurate than traditional two-piece field installed solutions.
- Average Responding
"Average responding" algorithm gives a RMS output on pure sine waves. Perfect for constant speed (linear) loads.
- 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).
- UL, CUL and CE Approval
Accepted worldwide.
Applications:
- Automation Systems
Analog current reading for remote monitoring and software alarms.
- Data Loggers
Self-powered transducer does not drain data logger batteries.
- Panel Meters
Simple connection displays power consumption.

AT Current Transducers from NK Technologies combine a current transformer and signal conditioner into a single package. The AT Series has jumper selected current input ranges and industry standard 4–20mA, 0–5VDC or 0-10VDC outputs. The AT Series is designed for application on 'linear' or sinusoidal AC loads. Available in a split core case or two types of solid core cases.
