Because my loads are well under the unit power rating these unit will allow me up to about 90 minutes to get the electronics completely off if the power get real erratic.

My building is next to an expressway - when they were expanding said expressway, there were several instances where the whole campus lost power.

This spring we've been having power issues (bad for computers obviously) and I took the dive to protect my hardware

Outstanding product, working perfectly for our power poor area.
