Principle introduction
The principle of TRSS-48300 embedded power supply system is as follows:
The system is powered by three-phase AC mains power through the AC input circuit breaker, all the way to supply power to the rectifier module; at the same time, the three-phase samples are sent to the monitoring board for AC voltage detection. After the output of the rectifier module is combined, the negative pole is divided into two channels. The first channel is output to the negative input terminal of the DC load through the DC contactor and the circuit breaker respectively, and the second channel is connected to the negative input terminal of the battery through the main shunt and the circuit breaker;The DC contactor protects the battery from over-discharge under the control of monitoring; the positive pole of the output of the rectifier module is connected to the positive pole of the load and the positive pole of the battery is connected to the output positive row.
