The invention provides a modular AC power conversion device. By optimizing the volume, reliability and protection of the switching power supply, two redundant core power boards are used to independently realize the AC 220V to ship power supply. The conversion of DC 24V power supply for working; and can realize autonomous current sharing, and when one of the external devices has internal fault (such as short circuit), it will not affect the normal operation of other external devices; realize the input voltage range 176VAC ~ 264VAC, frequency range 50Hz ±5% AC power conversion, the output voltage range is 24VDC±5%, providing 1 channel of AC 220V input, 1 channel of air plug DC 24V output and 6 channels of European plug DC 24V output; realizes the working environment of the ship cabin. The device connected to the European plug or aviation plug interface provides the function of DC power supply. |
