Description
Iskra MT174-MID Three-phase Smart Meter 200/5A
This meter is NOT suitable for use with Economy 7 tariffs Requires current transformers to operate. |
Product Overview:
The MT174 electronic three-phase meters are designed for measurement and registration of active, reactive and apparent energy and demand in three-phase four-wire networks. They can be connected directly to the network. The Polyphase MT174 features an RS communication interface that enables automated meter reading and readies the meter for use in AMI systems. Extensive anti-tampering functionalities provide maximum security for valuable metering data. High quality manufacturing process enables the meter to deliver the performance, expected in residential and small commercial environments.
The metering and technical properties of the meters comply with the EN 50470-1 and -3 European standards for active energy meters, classes A and B, as well as with the IEC 62053- 21 and IEC 62052-11 international standards for electronic meters of active energy for classes 1 and 2, and optionally with the IEC 62053-23 international standard for electronic meters of reactive energy for classes 2 and 3. A built-in time-switch complies with the IEC 62054-21 and IEC 62052-21 standards.
It enables energy registration in up to four tariffs. The meter software complies with WELMEC 7.2 Issue 1 Software Guide (Measuring Instruments Directive 2004/22/EC). The MT174 meters are designed for mechanical environment M1, electromagnetic environment E2 and climatic environment -40°C ... +60°C, relative humidity 95%
non-condensing, closed location. The meters can be installed in any position. The meters are designed and manufactured in compliance with the ISO 9001 (2000) standard.
Key Features:
- Solar PV Generation meter to collect FIT payments
- 120 Amp Three-phase kWh meter
- OFGEM/MID Approved No SI 12-11-007, latest generation ISKRA meter
- Equivalent specification to Elster A1100 three phase meter
- Import/Export Energy
- Tariff control input
- Small size modern design
- Pulse output
- Cost Effective
Photovoltaic Use:
The MT174 complies with the requirements of the »Leitfaden zur Bewertung der Zuverlässigkeit und Messbeständigkeit von Elektrizitätszählern und Zusatzeinrichtungen« published by the German VDE (Verband der Elektrotechnik Elektronik Informationstechnik) in March 2011. This means that the meter is resistant to the symmetrical perturbation currents emitted by PV converters in the range 2 - 150 kHz and may therefore safely be used in a photovoltaic installation.
Owing to periodical improvements of this product, the supplied product can differ in some details from data stated in this description.
