PURPOSE: A low voltage distribution board system and a power supply controller of a low voltage distribution board quickly and accurately supply stable power to a customer by appropriately switching power dually supplied, thereby maximizing efficiency. CONSTITUTION: A low voltage distribution board system includes a first potential transformer (212), a second potential transformer (222), a first air circuit breaker (213), a second air circuit breaker (223), a third air circuit breaker, and a power supply controller (240). The first potential transformer and the first air circuit breaker are arranged on a first power line (201), and the second potential transformer and the second air circuit breaker are arranged on a second power line (202). The third air circuit breaker is connected to the first power line and the second power line in parallel to make a tie shape with the first air circuit breaker and the second air circuit breaker.
