DESCRIPTION
MC750ATH is an important device for permanent monitoring measuring and analysing single-phase or three-phase electrical power network.
The meter measures RMS value according to the principle of fast sampling of voltage and current signals. A built-in microprocessor calculates measurands (voltage, current, frequency, energy, power, power factor, THD phase angles, etc.) from the measured signals.
MC750ATH performs measurements in compliance with regulatory requested standard EN 61000-4-30.
All required measurements and alarms can also be stored locally in an internal memory. With the RS232/RS485 or Ethernet/USB communication the meter can be set, measurements checked and stored data downloaded.
APPLICATION AND BENEFITS
MC750ATH Network recorder is intended for monitoring, measuring and recording of electrical quantities of a three-phase electric-energy distribution system.
Identifying relevant fixed measuring points is the most important task prior to complete system installation. This system itself will not prevent disturbances in network but it will help diagnose their origin and effects. This is possible only with system approach by using time synchronized meters with wide range of measuring parameters.
Technical Documentation
MC750ATH Network Recorder 3
Database records can involve numerous parameters of three-phase system, power quality parameters, physical parameters (temp., pressure, wind speed …) as well as alarms and detailed time-stamped event logs.
NOTE!
Stored data depends on device type and settings.

DESCRIPTION OF PROPERTIES
Measurands
RMS values of currents and voltages.
Measurements of energy, power and power factors in all 4 quadrants.
Minimal/maximal values.
Average values of measurands per interval.
Measurement of THD values of current and voltage (from 0 to 400 %).
Harmonic analysis of phase, phase-to-phase voltages and currents up to the 63rd harmonic.
Recorder
A built-in recorder (8 Mb) enables storing of up to 128 measurements and detected alarms (up to 32).
Memory card
The meter is provided with a slot for a full size SD* (128 MB to 2 GB) memory card formatted to FAT16 that can be used for transfer of measurements from the internal memory, meter setting and software updating.
* - Please note that not all SD memory cards are supported. Order at Iskra, d.o.o. to assure functionality.
Alarms
Alarms are powerful tool for MC750ATH Network recorder control and supervision features.
MC750ATH Network recorder supports recording and storing of 32 alarms in four groups. A time constant of maximal values in a thermal mode, a delay time and switch-off hysteresis are defined for each group of alarms.
For each parameter is possible to set limit value, condition and alarm activation action (sound signal and/or digital output switch if available).

Real time synchronisation
Network time protocol (NTP):
MC750ATH Network recorder supports NTP time synchronisation. Ethernet access to NTP server is required for proper operation.
NOTE!
NTP can usually maintain time to within tens of milliseconds over the public Internet, but the accuracy depends on infrastructure properties - asymmetry in outgoing and incoming communication delay affects systematic bias. It is recommended that dedicated network rather than public network is used for synchronisation purposes.
Communication
MC750ATH Network recorder has a wide variety of communication possibilities to suit specific demands. The meter is equipped with RS232/RS485 (DB9 or terminal connection) or Ethernet (RJ-45 terminal) and USB (USB-B type) communication. It can also be equipped with communication port for EX104 extension unit.
COM2 port is optional and can be ordered as one of I/O modules.
Different configurations are possible (to be specified with an order). Configuration COM1 COM2

RS232/485
/ 2 RS232/485 RS232 or 485
3(1)
Ethernet & USB
/ 4(1) Ethernet & USB RS232 or RS485
(1) Galvanic separation between Eth. and USB is 1 kVACRMS
Table 2: List of communication configurations
MC750ATH Network recorder supports standard communication protocols MODBUS RTU, MODBUS TCP and DNP3.
Analogue extender EX104 (accessory)
If there is a demand for additional analogue outputs analogue extender EX104 can be used.
It is a standalone unit, connected to meter via module 2 (module for communication with EX104 needs to be specified at order). Up to 4 analogue outputs can be used with one meter. More information can be found in Analogue extender EX104 data sheet (E P22.495.400).
Supply
Power supply connection of the meters is adaptive. A universal power supply enables connection of the meter to DC (20 V−300 V) or AC voltage (48 V − 276 V, 40 Hz ... 70 Hz).
AC power supply enables connection of the meter to AC voltage.
Handling the costs
A special meter function is cost evaluation of energy (active, reactive and total) per tariffs. The meter itself enables tracing the costs in optional currency and calculates consumption by means of the adjustable tariff clock and electric energy price.

MEASUREMENTS
Online measurements
NOTE!
In MiQen settings, software device will represent itself as MC 750A.
Online measurements are available on display or can be monitored with setting and monitoring software MiQen.
Readings on display are performed continuously with refresh time dependent on set average interval whereas rate of readings monitored with MiQen is fixed and refreshed approx. each second.
For better overview over numerous readings, they are divided into several groups, which contain basic measurements, min. and max. values, harmonics and alarms.
Each group can represent data in visually favored graphical form or detailed tabelaric form. Latter allows freezing readings and/or copying data into various report generation software tools.
Interactive instrument
Additional communication feature of a device allows interactive handling with a dislocated device as if it would be operational in front of user.
This feature is useful for presentations or product training.
Selection of available quantities
Available online measuring quantities and their appearance can vary according to set type of power network and other settings such as; average interval, max. demand mode, reactive power calculation method.
Complete selection of available online measuring quantities is shown in a table on the next page.

Real time clock
A built-in real time clock is also without external synchronization very stable when device is connected to auxiliary power supply. For handling shorter power interruptions without influence on RTC, device uses high capacity capacitor battery. It ensures auxiliary supply (for internal RTC only) for more than two days of operation (6 years with battery).
To enable clock operation backup supercap is built-in.
Supercap life span approx. 2 days
Type Low power embedded RTC
RTC stability < 1 sec/day
Battery life span approx.. 6 years (at 23 °C)
Connection cables
MC750ATH Network recorder is equipped with European style pluggable terminals for measuring voltages, auxiliary supply, communication and I/O modules.
Measuring current cables can be connected in two ways. They shall be attached as through-hole connection without screwing or as detachable screw terminals.
NOTE!
Stranded wire must be used with insulated end sleeve to assure firm connection.

Technical Documentation
MC750ATH Network Recorder 17
Example of ordering:
MC750ATH with a universal supply is connected to 230 V voltage and 5 A secondary current on 50 Hz network. Ethernet & USB communication, watchdog output (plus one relay output) as I/O 1/2 and two pulse outputs as I/O 3/4. Through-hole type current transformers. RTC with supercap supply.
Voltage and current nominal value are due to auto-range fixed to max. nominal value and are therefore omitted from ordering code.
Connection type is user programmable and is therefore omitted from ordering code. Default is 4u connection.
