3-Phase Electric Measuring RTU monitoring transformer M2M Remotely monitoring electric unit
Model:S253 (For Transformer Monitoring)
Name:Cellular Transformer Remote Monitoring Oil level and liquid level application
The Cellular(GSM/GPRS/3G/4G/NB-IoT) 3-Phase Electric Measuring RTU is special designed for remote monitoring transformer, and measuring the 3-phase 3-wire, 3-phase 4-wire distribution power voltage, current, factor, watts, frequency, active power, reactive power, when overload or loss phase or exceed the pre-set value, then it will alert by SMS, Voice call, Cloud, APP, HMI, DSC immediately.
The Cellular 3-Phase Electric Measuring RTU is an industrial class, high reliability, high stability, and programmable Remote Terminal Unit (RTU). It embedded 32-Bit High Performance Microprocessor MCU, integrated special measurement chip and inbuilt industrial Cellular module. It provides 4 digital inputs, 2 relay outputs, 1 ambient sensor input for monitoring onsite temperature and humidity.
The Cellular 3-Phase Electric Measuring RTU also can be used for monitoring the safety and security of the transformer, e.g. overload, phase loss, oil temperature, oil level, burglarproof, fall down etc.
The Cellular 3-Phase Electric Measuring RTU can monitoring and operates the I/O ports by SMS, APP, Web Server, internet, timers and programmed inter-lock events automatically.
The Cellular 3-Phase Electric Measuring RTU inbuilt TCP/IP protocol stack over cellular network or Ethernet to make it suitable for internet of things (IoT) applications, it can be easily to operate by the provided cloud, app, and web server, or integrated to you IoT applications according to the TCP/UDP protocol, or integrated to SCADA systems by standard Modbus TCP protocol, too. This is very useful if you need remote control onsite devices with low cost solution.
