EMU Professional II 3/100 LoRa ext. Ant.
Product information
Der EMU Professional II 3/100 LoRa ext.Ant is a 3-phase
energy meter with MID approval and LoRa radio interface and is equipped
with an internal LoRa antenna as well as an external antenna connection
(SMA socket).Switching between the internal and external antenna is carried out on the display of the energy meter. The external antenna is not included in the scope of delivery.
The LoRa interface of the 3-phase energy meter EMU Professional II LoRa is based on the LoRa radio standard.
This means the energy meter can reliably transmit data over long distances, in areas without permanent communication or as a roaming device.
To ensure a stable and high-performance connection to the LoRa gateway, the LoRa interface continuously adapts the optimal transmission and reception parameters.
For easy integration of the energy meter, the status of the LoRa network connection can be viewed on the display at any time.
- Frequency band EU 863-870MHz
- Type: Class C device
- Two-way communication.
- LoRa interface is ready to receive at all times (Class C).
- The internal LoRa antenna has a signal strength of 14 dBm.
Note:
If the LoRa energy meter EMU Professional II is
operated in a LoRa network that does not support Class C devices,
the energy meter EMU Professional II acts like a
Class A device.
LoRa Decoder
The EMU Professional II LoRa is available directly as a template in the TTN network.
For integration into other systems, we provide the decoder on GITHUB. Link: GITHUB LoRa Decoder
LCD Display
A large 38x28 mm graphical LC display with LED backlighting enables the reading of parameters and settings with excellent visibility of the digits.LoRa Energy Meter Configuration
Each energy meter is supplied from the factory with the following configuration:
- Join mode: OTAA
- DevEUI (starts with 102CEF)
- Appkey
- AppEUI (10 2C EF 00 00 00 00 00)
The DevEUI and the AppKey can be read on the display; the AppEUI is always 10 2C EF 00 00 00 00 00
