POWER SUPPLY DEVICE

摘要

PURPOSE: A power supply device is provided to prevent a safety accident due to stoppage by automatically intercepting a power supply when an electronic component is escaped from a set location or water is sensed. CONSTITUTION: A relay(11) supplies/intercepts a supply voltage of 220 volts from a plug to an electronic component(1). A voltage generator(12) generates a voltage of 12 volts. A foot switch(13) is mechanically turned on/off according to the location change of the electronic component(1). A controller(14) provides the voltage of 12 volts from the voltage generator(12) to the foot switch(13). The controller(14) turns on the relay(11) when the foot switch(13) returns to an initial status and intercepts a power supply to the electronic component(1). The relay(11), the voltage generator(12), and the controller(14) are installed at an inside of a case.
