Hello all,
We are working on a power solution design for an IT rack in an industrial environment, where they are trying to avoid the use of traditional UPS w/ batteries.
The IT enclosures have dual 30A input power. The input power sources are not in-phase, which causes issues with reverse power surge in current design when power transfers between sources.
The current design has input power coming into a dual-input Power Transfer Switch, with single output to a UPS for conditioning. Due to input sources being out of phase, power transition between input sources causes breaker trips because the UPS is not aware of the input change and so does not put inrush limiter in-line during transition.
We are trying to figure out if there is a dual-input power conditioner, or dual-input PTS that can handle the transition between out-of-phase sources without a battery to maintain power during the transition. There are dual-input UPS that can handle this scenario, but only with a battery to allow transition to on-battery condition temporarily during the input transition.
Any thoughts or help would be greatly appreciated!
