MPR-3 series analyzers are 3 phase network analyzers. They are microprocessor-based devices designed to measure all parameters of an electrical network, calculate consumption and display them on the LCD screen.
Thanks to the RTC clock chip and flash memory on the device, the operations performed by the operator such as interruption records, time and setting changes, reset operations are recorded in real time. These records can be remotely read and monitored with Modbus RTU protocol over RS-485 communication line.
The current connection is made by connecting to a 1A or 5A secondary current transformer, depending on the selected model, or to a current transformer with mV voltage output with RJ-45 connector.
The connection control function should be used against the problem of exposed live ends that may occur due to possible rupture in the terminals.
