Applications
This is a MPR-1 series 3-phase mains analyzer. It is a microprocessor based device which
is designed for measuring all parameters of an electricity main; calculate consumptions and
transferring desired parameters with Modbus and I/O outputs.
Thanks to the RTC clock chip and ash memory of 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 it to a 1A or 5A secondary current
transformer.

Terminal Structures
The terminal structures according to the models are described in this section:
Structure of the MPR-14S Terminal:
Current Terminals: K1, L1, K2, L2, K3, L3
An external current transformer must be used for the 3-phase system connection to these terminals
where the current up to 5A can be input.
Supply Terminals: A1, A2
Please, apply 95-270 VAC/DC (12-50 VDC for MPR-1X-D series) supply connection through
these terminals.
Voltage Terminals: N, L1, L2, L3
Please, apply 3-phase voltage connection through these terminals.
Communication Terminals: A(+), B(-), GND, TR
RS-485 communication terminals are used for Modbus RTU communication connection. A (+)
and B (-) terminals are connected in parallel between devices.
When the communication distance exceeds 10 meters and there are more than one device on
the line, communication instability may occur. In this case;
• A 120 Ohm connection resistor from the device box is installed between the A (+) terminal and
the B (-) terminal,
• Short circuit between the TR terminal and the A (+) terminal.
In this way, line balancing is done.

CONNECTION TYPES
As there are shunts at the current measurement inputs of the device, it is mandatory to use
a current transformer except for the connections of current inputs. If, the device will be used
on the same current line by means of analyzers with other shunts, it is recommended that the
device is located at the extreme point.
The device has 5 different connection types. These connection types are described in the
following schemes:
3P4W (Three-Phase Four-Wire) Connection
As it is seen below, four voltage and three current connections including the neutral line are
established in this connection type.

13
3P3W (Three-Phase Three-Wire) Connection
As it is seen below, three voltage and three current connections are established in this
connection type.
ARON Connection
Three voltage and two current connections are established in this connection type. As it is

RS-485 communication terminals are used for Modbus RTU communication connection. A
(+) and B (-) terminals are connected in parallel between devices. When the communication
distance exceeds 10 meters and there are more than one device on the line, communication
instability may occur. In this case;
• 120 Ohm line coming out of the device box between A (+) terminal and B (-) terminal.
