Applications
This is a MPR-2 series 3-phase mains analyzer. It is a microprocessor based device which is designed
for measuring all parameters of an electricity mains, calculate consumptions and reflect these values on
the LCD display.
Thanks to its clock chip and flash memory of the device, the blackout logs and the processes performed
by the operator such as the time and setting changes, resets and etc. are saved in real time. These logs
can be read and followed by the Modbus RTU protocol through the RS-485 communication port.
Current connection is done according to the selected model through 5A direct connection to the current
transformer with CT25 and RJ-45 connector and mV voltage output.
The connection control function which is described in detail in the 15th page should be used against
open live ends due to possible fractures at terminals.
