Product Description
The EM540 is a direct-connection energy analyser, for dual- and triple-phase systems up to 415 V L-L and current up to 65 A. In addition to a digital input, the unit can be equipped with a static output (pulse or alarm), a Modbus RTU communication port or an M-bus communication port (depending on the model).
- Measures active, reactive and apparent energy
- Measures the main electrical parameters
- Measure the load hours and analyser hours
- Measure the total harmonic distortion (THD) of current and voltages
- Data can be transmitted to other systems via Modbus RTU or M-Bus
- Manage a digital output for pulses or alarm transmission
- System and phase variables (V L-L, V L-N, A, W/var, VA, PF, Hz)
- Displays the consumed active energy with a resolution of 0.001 kWh
- Frequency value is available with a resolution of 0.001 Hz via Modbus
- Average value calculation (DMD) for current and power (kW/kVA)
- Modbus RTU RS485 (data repetition every 100 ms)
- Continuous sampling of each voltage and current
- Conforms to the performance requirements specified in EN IEC 61557-12-1
