AC Series: Quick Install, Precise Readings

Current Precision

Signal Stability

Rapid Response

High Accuracy AC Transducer

It directly converts AC current from the main circuit into standard DC output signals such as 4–20mA, 1–5V, and 0–10V, enabling easy integration with PLC, instruments, and control systems.

 

The integrated structure combines a current transformer and transmitter into one compact rail-mounted design, featuring high precision, fast response, low power consumption, and stable performance.

 

It is equipped with overload, over-current, over-voltage, reverse polarity, short-circuit, and surge protection functions, ensuring reliable operation in complex industrial environments.
