Communication function: rectifier can CAN and monitoring unit communication. Rectifier module output voltage and current, rectifier protection and alarm information is sent to the monitoring unit, to accept and carry out the control commands issued by the monitoring unit, as follows. Rectifier module communication functions, remote signaling: the rectifier protection signal (AC input voltage, output over voltage, rectifier module temperature and other signals) and fault signal to the monitoring unit; telemetry: Measuring rectifier output voltage of the output voltage, current, reported to the monitoring unit; 3, remote control: according to the command of the monitoring unit, rectifier on / off all / float conversion; 4, remote adjustment: according to the command of the monitoring unit, adjust the rectifier module , according to the command of the monitoring unit, adjust the rectifier output current in the range of 10% to 100% limit;
