Abstract
A conditioning circuit for providing a reliable source of supply power has a source of interruptible power, a source of uninterruptible power, a first voltage limiting circuit supplied with power from the interruptible source, a normally off second voltage limiting circuit supplied with power from the uninterruptible source and a monitoring circuit for detecting interruptions in the power supplied by the interruptible source and triggering the second limiting circuit to an on condition. An adjustable timing circuit is associated with the monitoring circuit to control the on condition of the second limiting circuit to restrict its on condition to a predetermined desired period.
