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.
A(+) B(-)

Structure of the MPR-15S-22 Terminal:
DOC terminals is referred to digital output common, digital output reference connection is done
with this terminal.DO1 and DO2 is also referred to 1st and 2nd digital output terminals.
INC terminal is referred to Input Common and it is the digital input reference. IN1 and IN2 are also
referred 1st and 2nd digital input terminals.
Digital Input Terminals: INC, IN1, IN2
As the INC terminal will be the joint point (reference), the IN1 and IN2 inputs are used
as digital inputs between 5-30V. Inputs have 1kV insulation level.
Digital Output Terminals: OC, O1, O2
As the OC terminal will be the joint point (reference), the O1 and O2 terminals are used
as insulated outputs. As it can be seen from the following gure, these Open Collector
outputs should be fed by an external supply for operation.

Structure of the MPR-16S-21 Terminal:
Different from the MPR-16S-21’den these terminals which are used for relay output are the
terminals next to the voltage terminals. They are indicated with the key symbol on the front view.
The terminal structure of the MPR16S-21 model is as in the following:
Digital Input Terminals: INC, IN1, IN2
As the INC terminal will be the joint point (reference), the IN1 and IN2 inputs are used
as digital inputs between 5-30V. Inputs have 1kV insulation level.
