SHORT CIRCUIT STATE DISPLAY DEVICE FOR POWER SUPPLY FOR BS CONVERTER

摘要

PURPOSE:To prevent an output terminal of a converter power supply for a BS antenna being in a state of short circuit or close thereto and in the overload state for a long time with respect to the short circuit state display device for an output terminal of a converter power supply in an equipment provided with the converter power supply of the BS antenna. CONSTITUTION:A voltage at an output terminal 1 of a converter power supply of a BS antenna and a preset reference voltage are compared with each other and the state of a terminal voltage lower than the reference voltage due to a short circuit at the output terminal is detected and display by a light emitting element 6 or a character display on a video screen 12 is implemented to inform the user of the fault state.
