DCS system UPS frequency

2016-02-16View Original

Thread Content

The power supply frequency in the DCS system is 60Hz; therefore, the input frequency for selecting the UPS should also be 60Hz. 1) Should the frequency supplied to the DCS be 60Hz or 50Hz? 2) What should be the power supply frequency for the instruments powered on-site? Some experienced expert could please give some guidance.
