With a one-to-three design, the current transformer can be
applied to measuring up to three different objects' electricity.
The user-friendly current clamp probe is designed for non-invasive and quick installation, eliminating the risk of circuit damage or power interruptions.
The CT3xx is designed to derive power directly from the measured circuit, eliminating the constraints of batteries while ensuring seamless operation
Outperform other competitors on the market, CT3xx boasts an impressive high sampling frequency of up to 3.3kHz, guaranteeing unparalleled accuracy and detail.
At One-Second Interval
Calculate accumulated ampere hour in real-time at a one-second interval. This enables precise current consumption monitoring
and analysis, achieving goals such as energy conservation and reduced operational costs.
Current Threshold Alert
Set minimum and maximum current thresholds, and receive instant alarms upon threshold triggers for swift action.
Over-Current Alert
Receive instant alerts when the actual current exceeds the rated limit, accompanied by a smart LED indicator flashing every 2 seconds for swift visual confirmation of the alarm status.
Temperature Threshold Alert
An external wire temperature sensor is available, triggering alerts when the wire temperature reaches a set threshold.
Say goodbye to the hassle of wires. This simplifies the installation process, reduces labor costs, and allows for more flexible placement.
By utilizing the global IoT standards of LoRaWAN®, the CT3xx enables seamless communication from electrical distribution panels across multiple stories of commercial and industrial buildings. It ensures uninterrupted wireless transmission which is also featuring strong stability, penetrability, and compatibility.
CT3xx is equipped with a high-gain antenna, ensuring stable signal transmission. Moreover, the mini stubby antenna and magnetic antenna are also offered as optional choices to meet your specific needs.
