Should UPS use a high-frequency unit or a low-frequency unit?
Thread Content
As the title indicates, it usually refers to DCS systems or PLC systems: several computers plus several cabinets. The required capacity for UPS power can be calculated, but I’m not very familiar with the difference between line-frequency and high-frequency UPS units. I hope experts can offer some guidance on whether line-frequency or high-frequency UPS units should be used for DCS or PLC systems
If it is for civilian use, it is recommended to use high-frequency units, as the voltage in the power grid is relatively stable, and the price is also lower. However, in factories, where the power grid is not very stable and there is a lot of noise, industrial-frequency machines are recommended, as they offer much better stability and a longer service life compared to high-frequency machines! :)
UPS – are there also high-frequency and low-frequency types? Some new problems have arisen again, right? ........
Not sure what to buy, so I’ll draw lots. . . .
A few computers and some cabinets – it’s really not cost-effective to use power-frequency machines. If you really have the money, go for high-end power frequency machines like AEG/GUTOR. Actually, the Suntak Castle series alone is sufficient.
