Insulatior for a multi-power system

摘要

This invention relates to an insulator for a multi-power system, which is used to resolve the current leakage which comes from each power supplied to the corresponding devices which are not being correctly operated. The isolating device includes: a first power supply for providing an operating power to the isolating device; a level detector for detecting the voltage level of the operating power; a signal isolation controller for changing the output level of the circuit supplied by the operating power based on the operating power detected; and a second power for supplying a real-time power to circuit for power saving operation based on the changed output level.
