A, product overview
With the rapid development of China's communication, electric power, UPS industry, quantity of accumulator is rapidly increasing. At present we battery usage conditions, often there will be some beat all the situation, in order to secure the use of batteries, the country has issued relevant standard, in some occasions the need to install the necessary device for battery monitoring, the products are mainly used in the above situations.
Two, function introduction
1, the battery voltage monitoring.
2, the temperature real-time monitoring.
3, can simultaneously monitor 254 batteries.
4, automatic sampling channel correction.
5, take the reverse voltage protection measures.
Three, installation
Sampling module, communication interface module is connected in series between the RJ11 interface, via communication lines, up to 254 module series.
Four, communication
The main control unit according to each module address access to it. Module default address is 0, ask for the main control unit in the power distribution for the address.
