DCS系统的供电系统是其运行的基础，电源负荷不要超过60%，以免电源高负荷运行。同时要考虑用高品质的电源，一般笔者采用UPS电源，采用两台UPS互为备用最好，一台出现故障后备用机能够无扰切换，提高电源的可靠性。UPS输入电源不要采用电气的同一母线，要根据电气厂用接线取可靠性高的不同母线段电源，这样保证电气一段母线出现问题后不会影响DCS系统的电源。
DCS电源系统(UPS、电源柜等)在现场安装时要安装在满足无尘、无振动、防腐等要求的电子设备间内，同时安装完毕通电前把电缆孔封堵，以防泄漏蒸汽从电缆孔进入电源系统造成电源短路。在DCS电源上电后，要在UPS、电源柜等设备上挂“设备带电运行禁止操作”标识牌，更不准可以在DCS电源系统上接入与DCS系统无关的负载，如检修电源、检修照明、充电设备、空调等。
