CT310 is widely used for energy monitoring in smart buildings, machine failure detection and prevention, etc. Perfect for smart buildings, smart city deployments or industrial use-cases.
- Self-Powered Operation
- Superior Accuracy with Up to 3.3kHz Frequency
- Real-time Accumulated Ampere Hour Calculation
- Non-invasive Installation
- Irregular Current/Temperature Status Alert
- Innovative One-to-Three Design
- LoRaWAN® Wireless Deployment
Multi-Target Current Measurement
With a one-to-three design, the current transformer can be applied to measuring up to three different objects' electricity.
Self-Powered: No Batteries, No Limits
The CT3xx is designed to derive power directly from the measured circuit, eliminating the constraints of batteries while ensuring seamless operation.
Superior Accuracy
Outperform other competitors on the market, CT3xx boasts an impressive high sampling frequency of up to 3.3kHz, guaranteeing unparalleled accuracy and detail.
Efficient Energy Tracking 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.
