Cellular BTS Electricity Measuring RTU
The Cellular (GSM/GPRS/3G/4G/NB-IoT) BTS Electricity Measuring RTU is a powerful smart meter used for power internet of things solution, special designed for remote monitoring BTS (Base Transceiver Station) electricity power. It can separately measure the diesel generator power and electricity power parameters.
