Description
The Netvox wireless three-phase current detector is used to detect three-phase electrical input current. The device is compatible with the LoRaWAN® protocol, and integrates a chip module that conforms to the LoRaWAN® wireless protocol, and joins the gateway to display the collected data in the gateway. The device is powered by a battery and receives AC current through a current transformer. This device adopts open-loop current transformer, which can be easily connected to the device to be tested. The A phase line, the B phase line and the C phase line of the three-phase electric power are respectively connected to the corresponding current transformers.
Features
- LoRaWAN® Class A compatible
- Requires 2 x ER14505 AA Lithium batteries
- Frequency Hopping Spread Spectrum (FHSS)
- Improved interference immunity
