The system power supply of Zhejiang University central control DCS card esc-100 is divided into DC power supply (DC) and AC power supply (AC). DC power supply mainly refers to the power supply of 5V and 24V power modules of the system. According to different models, the power module can be divided into:
Power module: output 5V voltage o24v power module: output 24V voltage o5v / 24V power module: output 5V and 24V voltage, mainly used in remote cabinet.
电源模块的作用是将220Ｖ ＡＣ转化成5Ｖ ＤＣ或24Ｖ ＤＣ。电源模块的面板上都有故障指示灯，当供电模块出现故障时，相应的电压指示灯会熄灭，故障指示灯会亮红灯。
The function of the power module is to convert 220VAC into 5VDC or 24VDC. There are fault indicators on the panel of the power supply module. When the power supply module fails, the corresponding voltage indicator will go out and the fault indicator will light red.
In order to ensure the safe and reliable operation of the system, we require that the AC power distribution must be redundant, that is, two power supplies are required to supply power to the system. The recommended power supply mode is: 2 ways of 220VAC redundant power distribution, one way of power supply through ups and one way of direct power supply to the system through municipal power supply.
