Cellular 5-CH DC Power Measuring RTU
The Cellular (GSM/GPRS/3G/4G/NB-IoT) DC Power Measuring RTU is a smart power meter, special designed for remote monitoring 5-channel DC electricity power.
Measure each channel voltage, current, active power, active energy. When overload or exceed the pre-set value, then it will alert by SMS, Voice call, Cloud, APP, Wechat, Web Server, SCADA, HMI, DSC immediately.
