0-10, 0-20, 0-50 Amp Ranges, Top Terminals

Accurate
- Factory matched and calibrated single piece transducer is more accurate than traditional two-piece field installed solutions
Average Responding
- “Average Responding” algorithm gives an 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 helps conserve data logger batteries
Panel Meters
- Simple connection displays power consumption

AT Series Current Transducers 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.

Designed to provide an analog current reading for monitoring, data logging and panel meter applications, these transducers offer a choice of 0–5VDC, 0–10VDC or 4–20mA average responding or True RMS outputs. Self-powered and split-core options make these a cost-effective choice as a PLC input in motor status applications or where VFDs are involved

5.0

These are great inexpensive current transmitters. The hinged format allows for easy installation and you don't have to remove any existing wiring. The 4-20mA output easily integrates into a PLC, saving a lot of money on having to install a power monitor.

Faster Than Expected Delivery,

5.0

I have been using this same model of current transducer for many years in the R&D lab at my manufacturing company. So, if I were rating the equipment alone, I would give it 4 stars. Its a great transducer, but they do fail from time to time. Overall, the best current transducer for my needs (temps up to 200F and 2 to 50 amp range I require. However, I was expecting a couple weeks for them to arrive at my company and it only took four business days. Flex Core makes a solid product.
