Precise current transducers

Precision Current Transformers

Precision current transformers are dedicated to electronic measurements of current, both alternating and direct, in the range from 12.5 A to even 24 kA. Thanks to excellent linearity and high accuracy, these transformers are used in industrial and energy applications, including laboratories, medical research, industrial automation systems, and network parameter monitoring. Available in PCB-mounted versions, with a cable hole, and also with galvanic isolation, allowing safe integration into analog and digital circuits.

Precision Current Transformer - What You Need to Know?

The transformer outputs can be in the standard 0–10 V, current, or digital with RS-485 interface and Modbus protocol, allowing easy integration with control and monitoring systems. These transformers generate a signal proportional to the RMS current value, enabling precise current measurement in power electronics applications, electrical networks, and automation systems.

Our offer includes a precision current transformer tailored to various needs - we warmly invite you!
