Milesight Smart Current Transformer CT101 & CT103
The CT101 and CT103 are LoRaWAN® Smart Current Transformers for monitoring energy and analyzing consumption remotely.
The CT101/CT103 provide multiple current options to suit energy monitoring and support sending threshold alarms.
The compact size and clamp design allow them to be installed in any indoor space quickly and safely without de-energizing a facility, simplifying the installation and saving costs.
The CT101 and CT103 can be used with any LoRaWAN gateway or network server. When used with Milesight LoRaWAN gateways and the Milesight IoT Cloud solution, CT101 and CT103 CTs can be monitored via webpage or mobile app remotely, without any code or additional server installation.
The CT101 and CT103 are widely used for energy motoring and billing of smart buildings, machine failure detection and prevention, etc.
