The ECA2 single-phase meter is one of the world’s most compact metering units, ideal for a utility’s single-rate meter requirements or as a generation meter for Solar PV and micro-generation installations where feed-in tariff claims apply. It measures active energy (kWh) in both import and export directions, with clear registers shown on a large, easy-to-read LCD display. The meter is highly reliable, designed to withstand high voltage events and overcurrent, and is fully MID approved for accuracy and compliance. For security, the ECA2 is tamper-resistant with reverse energy fraud detection and a sealed-for-life design. An optical port compliant with IEC 62056-21 allows electronic meter reading and configuration using standard industry tools. A pulsed output version is also available for connection to BMS or other monitoring systems. The meter can be supplied with either a standard terminal cover or an extended cover to provide additional wiring space.
