A new development in emergency power for small to mid sized CPE telephone systems

Research and engineering for a new development in small emergency power systems are described. Insight is provided into the problems and solutions of providing clean stable power for small telephone and computer systems from small emergency generators. While large telephone systems have carefully engineered emergency power systems, the small user has had very few choices in powering a PABX or key system in the event of a long-term power outage. An alternative to very large battery back-up systems is discussed. This is an interruptible transfer switch that provides an interface to a small inexpensive generator.<>
