Friends,
I am working in african country, we are about to install Siemens S7-400 PLC in our process plant. We have severe power breakdown / fluctuation / under voltage problems from local electric co. The OEM who is supplying turnkey process plant has only considered Voltage stablizer for PLC system.
I am looking for suggestion as till now my experiance is in Cement Plants and there we always had UPS system for PLC's. I am now in a edible oil refinary. So somehow I feel uncomfortable with the idea of using only voltage stablizer. Just few days before power supply card of four PID controllers got blown due to flctuation. So considering the situation I am awaiting your suggestions.
