ISKRA MT174 CT - 3-ph CT Operated Generation Meter
The ISKRA MT174 CT - 3-ph CT Operated Generation Meter is a MID-certified three-phase electronic meter designed for accurate measurement and registration of active, reactive, and apparent energy in solar PV and generation systems, with CT operation for high-current applications.
Product Description
The Iskra MT174 CT is a polyphase multi-tariff meter suitable for import/export metering in three-phase networks. It features CT operation with a 200/5A ratio, making it ideal for larger installations where direct connection is not feasible. With photovoltaic readiness and anti-tampering protection, it ensures reliable performance in renewable energy setups. The meter supports up to four tariffs, RS485 communication, and pulse outputs for integration with energy management systems.
Key Features
- MID certified: Compliant for billing and accurate energy metering.
- Import/export metering: Measures bidirectional energy flow for generation and consumption.
- CT operated: 200/5A ratio for high-current applications without direct wiring.
- Multi-tariff support: Up to four tariffs with external changeover.
- Communication interfaces: RS485 and optical port for data retrieval.
- Pulse outputs: Two configurable outputs for energy or demand.
- Anti-tampering package: Extensive protection against fraud.
- Photovoltaic ready: Designed for solar PV integration.
