Type: Enertex 1149-85-RT KNX SmartMeter with converter up to 85A with RT (real time)

The KNX SmartMeter 85A RT 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 a three-phase system 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
- Plug-in current sensors for measurement range from 2 mA to 85 A per phase and power from 0.5 W to 58 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 down to 0.002% of nominal current (= 2 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 is from 0.5 W to 19,550 W or 58,650 W (three-phase)
- 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 electricity
- Real-time analysis of network-related electrical equipment failures, malfunctions, and damage
- Special energy meters for monitoring photovoltaic systems (balance, production and consumption meters)
- DIN rail case with 4M

The KNX Smartmeter 85A RT can also be operated without the KNX bus. For this purpose, a 24 V DC power supply must be connected to the KNX terminal. In this mode, all measured data without mains harmonics are recorded on the SD card every minute

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