SEM

Smart Energy Manager

Device Description

SEM is a compact and highly capable monitoring and control device for commercial, industrial and utility based energy management applications. It supports most of the common industrial communication protocols ( Modbus, IEC104, IEC62056 etc.) as well as those being used for IoT applications (REST, MQTT, CoAP etc.). Owing to its embedded click-on communication board, you can choose any type of media over GSM, Wi-fi, Ethernet, Zigbee or Lora. SEM’s power measurement feature provides monitoring of two three-phase circuits simultaneously with a sampling rate of 3.2kHz. Besides, it has an SD Card option up to 32GB to restore data even if there is a loss of communication. Its embedded and expandable digital inputs and outputs make it very easy to have more information from other communicable devices
opening the door to a world of connectivity and control.
