The Vega M-BUS-2 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 with 6400 mAh capacity.
Converter M-BUS-2 may operate in the independent poll mode of the metering devices and can be used only with the next supported devices:
• Heat meter «Teplouchet-1»
• Heat meter «STE 21 «Berill»
• Heat meter «Danfoss Sonometer 500»
• Heat meter «ELF-M Тепловодомер»
• Heat meter «WESER Heat Meter»
• Heat meter «Kamstrup Multical 801»
• Heat meter «Kamstrup Multical 402»
• Heat meter «Landis Gir T230 ULTRAHEAT» (support is possible by individual order)
• Heat meter «Sharky 775» (support is possible by individual order)
The list of supported meters is depend on firmware version, so you should clarify the issue of support for a particular meter when ordering.
