MCS301 meter - product Manual 1.25 MetCom Solutions GmbH
3 Basic functionality
The basic functionality of the meter is described below:
• High accuracy
Digital measured data processing with a digital signal processor (DSP) and high
sample rate for accurate, flexible measured-value processing the energy and
demand in all 4 quadrants. Additionally, Power Quality data are provided
• Configuration
User-friendly readout and configuration tool Blue
2
Link, enabling users to define their
own different function variants.
• Load profile for billing and power quality purpose
Providing an extended load profile functionality all billing data as well as the Power
quality data, like voltage, current, harmonics and THD can be stored over a longer
time period and can be readout by the connected HES system.
• Anti-Tampering features
The meter supports a lot of Anti tampering features like
• terminal and main cover detection
• communication module removal detection
• magnetic field detection
• Communication modules for AMI application
The MCS301 meter is prepared for AMI application by using communication
modules (GSM / GPRS / LTE, Ethernet …), which can be exchanged in the field.
• Power supply
The meter's power supply is available for 2 different application
• Transformer rated power supply for dedicated nominal voltage level, like
3x220/380V–3x240/415V or 3x58/100V-3x63/110V
• Wide range power supply working from 3x58/100V – 3x277/480V
i.e. if two phases fail, or one phase and the neutral, the meter will remain fully
functional. If phase and neutral conductor will be connected in a wrong way the
meter displays an alarm. All meter types of the MCS301 are earth fault protected; in
that case the meter can handle a voltage of 1.9Un for more than 12h.
• Readout during power outage (only with external battery support)
The behavior during power outage is described below.
• After pressing the alternate button the LCD will be switched ON.
o All data can be displayed on the LCD.
o All data can be readout through the optical interface.
• The LCD will be switched OFF after the following events:
o Without pressing the push button within 10s.
o At reaching the end of the data readout list
• Auxiliary power supply
The CT meter can be supported with an auxiliary power supply from 48 – 230V
AC/DC. In case the auxiliary power supply is connected, the meter is powered from
the aux.power supply, otherwise the meter power supply is used
