The meter is compliant with Directive MID Certificate number 2014/32/EU 0120/SGS0216.
The purpose of the LE-03MQ CT is to measure consumed and supplied active energy, inductive and capacitive reactive energy, phase voltages, phase currents, frequency, active power, reactive power, apparent power, power factor, AE+/AE- [kWh], RE+/RE- [kvarh], U1, U2, U3 [V], I1, I2, I3 [A], [Hz], P [W], Q [var], S [VA], cos, THD harmonic %, and demand for power and electricity (kW, kvar, kVA, I).
The meter also has a pulse output (SO+/SO-) which can be used to connect a pulse meter for reading pulses generated by the counter. The input and output terminal covers of the meter are sealable to prevent any attempts to bypass the meter. Each meter is marked with an individual serial number that allows for unambiguous identification.
