EM210 3-Phase Energy Analyser
Three-phase energy meter with removable front LCD display unit. The same unit can be used either as a DIN-rail mounting or a panel mounting energy meter. This general purpose three-phase energy meter is suitable for both active and reactive energy metering for cost allocation but also for main electrical parameter measurement and retransmission (transducer function).
Possibility to display also exported active energy (e.g. in case of regenerated energy in lifts or similar applications) harmonic distortion information are available for the voltages and the currents, up to the 15th harmonic. An hourcounter meter is available to link the energy consumption to the relevant working hours and an hourcounter to link the exported energy to production hours. Housing for DINrail mounting with IP40 (front) protection degree.
Current measurements carried out by means of external current transformers transformers, 5A or 333mV (CTV series), or ROG4K, Rogowski coil solution without external integrator. Voltage measurements carried out either by means of direct connection or by means of potential transformers. EM210 is provided, as standard, with a pulsating output for active energy retransmission. In addition a 2-wire RS485 communication port is available as an option.
