![CDATA[The KNX Smartmeter (4TE DIN rail) is a bidirectional meter for active and reactive energy/power as well as network quality monitoring. Accuracy class 1, measurement in a three-phase system or three single-phase systems. All measured values (current, voltage, power, energy, factor, THD, harmonics) are displayed on the KNX bus and recorded on an SD card. Lossless measurement with external push-through current sensors (2mA to 85A/phase). Voltage range 0 to 460VAC, active power range 0.5W to 19550W or 58650W (three-phase). ETS application offers various functions for load control, self-energy optimization with PV, tariff switching, monitoring functions for network quality and event messages when limit values are exceeded. Network quality: harmonics up to the 50th harmonic of current and voltage. Operation exclusively via KNX bus. Note: 3 x current sensor (Rogowski transducer) each with 1.5 m measuring cable and centering clip included.]]>
