Identification apparatus for back-up type power supply systems has signal detector that determines coupling and installation conditions of real and dummy power supply devices based on identification signals from potential detection points

摘要

Potential detection points are installed on a real power supply device (10) and a dummy power supply device (20) to generate a real identification signal and a dummy identification signal having a different signal level. A signal detector (31) located on a power integration back panel (30) receives the identification signals to determine coupling and installation conditions of the real power supply device and the dummy power supply device of the backup-type power supply system. A display lamp set (40) displays the installation conditions of the real and dummy power supply devices.
