Principle introduction The principle of IPS30000-8U300A embedded power supply system is shown as follows:

The power supply of the system is switched between the mains and the oil generator through the AC input circuit breaker to supply power to the rectifier module; at the same time, L1, L2, L3, and N are sampled and processed and then sent to the monitoring signal interface for AC voltage detection.After the output of the rectifier 第 3 页 共 11 页

The first route is output to the secondary load DC input terminal through the user's first shunt and the primary power-off DC contactor.

The second route Output to the important load DC input terminal through the first user shunt, the third output to the secondary load DC input terminal through the second user shunt and the primary power-down DC contactor, and the fourth output to the important load DC through the second user shunt Input terminal, the 5th channel outputs to the secondary load DC input terminal through the user-shunt and the primary power-down DC contactor, the 6th channel outputs to the important load DC input terminal through the user-1 shunt, and the 7th channel passes through the user-shunt output to the DC input terminal of the secondary load, the 8th channel outputs to the DC input terminal of the important load through the user-shunt, the 9th channel passes through the shunt and the DC contactor to the negative pole of the battery input, all DC The contactor realizes battery over-discharge protection for the battery under the control of monitoring.

All shunts send signals to the monitoring board, and the monitoring board calculates and processes the current collected from user 1 to user 4, and at the same time performs metering as required and sends it out through the display screen. 5.
