1149-630 KNX SmartMeter with converter up to 630A

Type: Enertex 1149-630 KNX SmartMeter with converter up to 630A

The KNX SmartMeter 630A is a bidirectional meter for measuring active and reactive energy or power, as well as for network quality analysis. The measurement is performed either in three-phase systems or in three independent single-phase systems with accuracy class 1 (1%). Thanks to the battery-powered real-time clock, operation is also possible without the KNX bus.

Features of the device:
- Integrated real-time clock with battery for operation without KNX bus
- Measured data is saved to the SD card every minute
- Current sensors for a measurement range from 10 mA to 630 A per phase and power between 7.5 W and 293 kW
- Electricity meters of accuracy class 1 (1% for active and reactive energy)
- Use of high-precision current sensors (Rogowski coils), which are calibrated to the device in the factory
- Accurate measurements of very low currents up to 10 mA
- Low-loss current measurement (< 2 mW loss)
- The supplied current sensors are suitable for surface mounting and can be installed directly at the point of power supply from the mains
- Since it is powered exclusively via the KNX bus, the device can measure currents and voltages even if there is no 230 V mains voltage at the voltage measurement inputs or if the voltage has been enabled
- The active power measurement range ranges from 7.5 W to 293 kW
- All measured values (current, voltage, active power, reactive power, active energy, reactive energy, power factor, THD-U, THD-I, network harmonics, unbalanced load, zero current, network frequency) are displayed on the KNX bus
- All meter values and measured quantities are also recorded in text form (standard csv format) with a time stamp on an SD card for further data processing
- In addition to specialized functions for power-based load management, optimization of own energy needs with PV systems, user or feed-in tariff calculation with tariff switching and to avoid load peaks, the ETS application also provides various monitoring functions
- Condition monitoring: exceeding limit values, events such as voltage failures, high voltage peaks, large network distortion, high reactive power consumption, very uneven 3-phase load (unbalanced load) or high neutral conductor load can be reported via KNX telegram
- Measurement of harmonics up to the 50th harmonic of current and voltage to assess the quality of electrical energy
- Real-time analysis of network-related electrical equipment failures, malfunctions, and damage
- Special energy meters for monitoring photovoltaic systems (balance, production and consumption meters)
- Case for DIN rail 4M

Power supply / connection:
- Power supply from the KNX bus or external 24 V DC power supply
Display and operation:
- LED for energy measurement 1 to 3, Power/SD-Write and programming mode
- Programming button
