The EMU Professional II 3/5 Modbus is an electronic 3x 230/400VAC three-phase kWh meter for DIN rail mounting and direct measurement up to 5A. The meter has various functions including measuring actual and reactive consumption, calculating the power factor (cos phi), and providing a clear insight into consumed and generated energy (import/export). The transformation ratio can be adjusted multiple times, with the changes being saved in an internal logbook. The meter is equipped with an integrated Modbus RTU (RS485) + ASCII interface.
The meter is MID B & D approved for billing purposes, certified for PV systems (according to DIN CLC / TR 50579: 2012), and suitable for energy management systems according to ISO50001. It is fully compatible with the EMU Joulio-Web energy management system software for monitoring and obtaining a clear view of all consumption data. The meter is protected against tampering and has a sealable connection cover. Additionally, all configurations are logged and archived.
