Milesight CT305 Three-Phase Smart Current Transformer EU868
Milesight's CT305 is a self-powered LoRaWAN Smart Current Sensor for the monitoring of energy usage in a 3-phase electrical circuit. The CT305 works on circuits carrying up to 500A - providing current consumption data though periodic and threshold (min/max) triggered messages.
CT305 can be easily installed next to an existing meter, and in distribution boards by a qualified electrician. CT305 can be widely used for energy motoring in domestic, commercial and industrial settings, as well as for machine run time and failure detection.
CT305 is battery-free as it's parasitically powered from the current passing through the cables being measured. This removes any need for ongoing maintenance.
The three current clamps provided are large enough to accommodate up to 36mm diameter cables, and feature a 1m cables back to the sensor itself for installation flexibility. The sensor antenna connects via a standard SMA connector - we can also supply external antennae to aid installations inside steel cabinets.
Key Features:
- Report the RMS current and accumulated current data periodically
- High measuring accuracy with a sampling frequency of up to 3.3 kHz
- Parasitic powered super capacitor means no batteries or external supply required
- Utilise a sampling rate of up to 1s for real-time monitoring and quick alarm response
- Compact size allows for installation in narrow spaces
- Non-invasive clamp design ensures easy and safe installation without the need for electrical power downs
- Equipped with LED indicator to indicate working status and alarms
- External SMA antenna
- Configuration via Downlinks or Milesight Toolbox app
- Sensor size: 38 × 39.7 × 16mm
- CT Clamp size: 65.52 × 90 × 43mm
- CTs accept Ф 36.6 mm cable
