POWER SOURCE CONTROL SWITCHING SYSTEM

摘要

Each digital module in a network is provided with a local power switching control subsystem wherein the local module uses a local power switching control logic card which controls main power and subordinate power units in a predetermined sequence. Power up/down conditions or incremental/decremental voltage conditions can be effected by a local operator or by an instruction from a remote master logic unit. The power subsystem can sense failure conditions and communicate this information to the remote master unit or to a local operator.
