+If you are considering using an Uninterruptible Power Supply (UPS) to guarantee operation of your Vescent products through a brown out or black out, great care should be taken in choosing the model.  Lower cost models tend to produce modified square wave voltage profiles.  The high-frequency components of such a voltage profile may interact poorly with the D2-005 (and down-stream active Vescent modules).  If you do choose to use a UPS, select a model that will provide a sine wave voltage profile without higher harmonic components to avoid potential damage to your high-value equipment.
