Carlo Gavazzi’s EM210 series has been upgraded with technological enhancements such as THD, Neutral current and hour counter to link the energy consumption to the relevant working hours as well as, the new CTV versions available in 2 input voltage ranges MV53 or MV63 and 333mV current signal.
Installation is fast and simple, thanks to the meter’s self-power supply from the voltage reference inputs, automatic phase detection with wrong-phase-sequence warning and fast application-oriented programming procedure.
Current measurements can be carried out by means of the external split core current sensor which when fitted restricts the voltage to the meter to 333mV; making it a favourable solution for the installer. By using split core current sensor technology, no primary wiring disturbances are needed in existing installations therefore it eliminates the need to disconnect or modify the power cables during installation.
A selection of variables can be programmed providing for active and reactive energy measurement or a complete set from 6 sets of 3-phase variables. Options include: system variables such as W, var, PF, Hz and phase-sequence; single-phase variables including A, PF and THD (A, V, up to 15th Harmonic); relevant phase to phase and phase to neutral voltages and phase currents. The THD can be enabled or disabled by the user. The EM210 can also calculate and display the neutral current instantaneous value.
