| 摘要 |
The present invention relates to a power distribution device and more specifically, to a power distribution device comprising a first power input unit receiving main power, a second power input unit receiving secondary power, a double switch unit which connects the first power input unit or the second power input unit and a power supply device, a capacitor which is charged and discharged by power applied from the main power, a bidirectional diode which is connected to the capacitor, and a relay coil which generates fundamental force for the double switch unit when the power supply from the main power is normal to rapidly perform the voltage source change to the secondary power when power supply from the main power is stopped. [Reference numerals] (206) Main power; (207) Secondary power; (AA) Load |
