Applications MPR-4 Series devices are microprocessor-based devices which are designed to measure all parameters of an electrical network, calculate the consumption values and display these on its LCD screen. Measured parameters will be recorded in real-time thanks to internal flash memory and Real Time Clock chip. These recorded values then can be accessed and monitored remotely via RS-485 line with Modbus RTU protocol. Ethernet feature can be used instead of RS-485.
Terminals Front Panel 6
