Hi everyone I was hoping if people here much smarter than me could help me out.
I'm a maintenance tech for a data center and I've been wondering how a UPS manufacturer decides what rectified voltage the DC bus runs at.
We use Toshiba/Mits 2MW UPS' and they both give out ~560vdc readings from the HMI. Is this a set in stone formula for the conversion? (Similar to how a full bridge rectifier will give ~670vdc when converting from 480vac for a VFD)
