PURPOSE: An uninterruptable power supply-integrated motor control center is provided to reduce the usage of cables by integrating devices into the control center. CONSTITUTION: A motor control center (100) includes a motor controller (110) and an uninterruptable power supply (120). The motor controller divides the low voltage electricity to each load and prevents the excess current flowing. The uninterruptable power supply is integrated in the motor controller, converts the power supplied from a cabinet panel (130) into a constant voltage, and provides the voltage to the motor controller. The uninterruptable power supply includes a rectifier, an inverter, a transformer, and a battery. |
