The power distribution unit has a critical task to ensure that the 115 VAC 400Hz power in the aircraft. 115VAC PDU has three phase inputs. There are voltage and current measurement units in the 115VAC PDU device. The 115VAC PDU saves space and reduce cable harness. It can also perform detailed tasks such as soft start, over current protection, short circuit protection, sequential opening, energizing the desired loads for power saving according to working scenarios. PD100370005AA and PD100190005AA models has different design approach to reducing sizes with different specs.
