Features

• 3-phase bidirectional counter for measuring active and reactive power
• Energy meter of accuracy class 1 (1% for active and reactive energy)
• Lossless current measurement via included, calibrated external current sensors
• Two current sensor variants available for different measurment ranges: 85 A or 630 A per phase
• Measures: Active and reactive power, active and reactive energy, voltage, current, power factor, unbalanced load, zero system current, THD, harmonics
• Output of all counter readings and measured values at KNX bus via group objects
• Recording of all measured values on microSD card in standard csv format with time stamp
• Special energy meters for supervision of solar collectors (balance, generation and consumption meter)
• Condition monitoring function: Indication of overload overvoltage, power failure, voltage distortion, current distortion, unbalanced load, zero system current
• Current sensors for a measurement range from 10 mA to 630 A per phase and power between 7.5 W and 293 kW
• Can also be used without KNX bus, as a battery-buffered real-time clock is built in. When operating without KNX bus, all data with time stamp are recorded every minute on the SD card.
