The Vega M-BUS-1 converter is designed for reading data from devices with M-BUS interface with subsequent accumulation and transfer of this information via LoRaWAN™ protocol to the gateway by means of radio communication at frequencies of the range 860-1000 MHz. The battery for the converter is an irreplaceable battery, designed for a lifetime of up to 10 years. With battery power, the converter operates as Class A LoRaWAN™ device. The converter can operate from an external power source with a voltage of 10 ... 36 V. In that case, the converter operates as Class C device. In addition, the M-BUS-1 converter has two security inputs that trigger the alarm message to the gateway.
