The Cellular Electricity Power IoT RTU is a powerful smart meter used for power internet of things solution, is special using for remote monitoring 100~400VAC of 3-Phase electricity power distribution safety and measurement, can measuring the 3-phase 3-wire, 3-phase 4-wire distribution power voltage, current, factor, watts, frequency, apparent power, active power, reactive power, active energy, reactive energy. Also, it provides Dual SIM, 2 digital inputs, 2 relay outputs, 1 ambient sensor input for monitoring onsite temperature and humidity, also 1 RS485 for extend I/O to monitoring oil level and temperature or read meters.
