Carlo Gavazzi’s EM210MV and ROG4K is faster to install than other Rogowski cables
Energy management specialist, Carlo Gavazzi has launched a Rogowski coil solution for the popular EM210MV 3 phase energy meter for retrofit applications. The ROG4K Rogowski solution which most importantly does not require an external power supply or external integrator makes installations faster and simpler, 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 are carried out by means of a ROG4K flexible current sensor which has a hole diameter from 115mm to 275mm and can measure a primary current from 20 to 4000Amps and guarantees Class 1 accuracy. It includes 3 coils in different colours to simplify the work of the installer and a secondary cable terminal with tag of the same coil colour to simplify and minimize wiring errors.
The EM210MV series offers single phase variables such as THD, Neutral current and hour counter to link the energy consumption to the relevant working hours as well as, compatibility with the CTV versions. Available in 2 input voltage ranges MV53 or MV63 and 333mV current signal as well as the new Rogowski cables.
