Battery backup should be used to supply emergency power for
those areas subject to frequent power outages or when operation
of the power window system must be maintained for a period of
time should a power outage occur.
Truth recommends the use of a UPS (uninterruptable power
supply) as a battery backup. They are widely available through a
variety of retail and commercial outlets and are primarily used to
supply emergency backup for computer equipment.
To determine the proper VA rating for a UPS, take 50 times
the number of transformers to be backed up by a given UPS.
Below is a list of the manufacturers who produce uninterrupt-
able power supplies which we have approved as compatible with
our power window systems. If you are considering using a UPS
not listed, please be sure the UPS is suitable for inductive (trans-
former) loads.
